Changelog

* Sat Apr 16 2022 Luigi Baldoni <aloisio@gmx.com>
  - Update to version 67.0.0
    New features and enhancements:
    * all: IETF BCP 47/RFC 5646 language tags: when deriving the
      legacy language element codes to use a language tag's ISO
      639 code is also potentially interpreted as an & its prefix
      is used as the legacy language code. For example, "Yue
      Chinese" = `yue` is not part of ISO 639-2. However, there is
      an extlang subtag `yue` with a valid prefix of `zh`
      ("Chinese"), and for "Chinese" there is an ISO 639-2
      language code: `chi`. In this example the IETF language
      element would be set to `yue` and the corresponding legacy
      element to `chi`.
    * all: IETF BCP 47/RFC 5646 language tags: grandfathered
      language tags are now supported.
    * all: IETF BCP 47/RFC 5646 language tags: all deprecated
      subtags from the IANA language subtag registry are now
      supported.
    * all: IETF BCP 47/RFC 5646 language tags: all lists of valid
      subtags have been updated from their respective
      authoritative sources.
    * all: IETF BCP 47/RFC 5646 language tags: all in the IANA
      language subtag registry are now supported, even those
      marked as deprecated and of type 'grandfathered'.
    * all: IETF BCP 47/RFC 5646 language tags: reduced the maximum
      number of extended language subtags that are present in a
      valid tag from 3 to 1 in compliance with RFC 5646 section
      2.2.2.
    * all: IETF BCP 47/RFC 5646 language tags: all language codes
      reserved for private/local use (`qaa`–`qtz`) are now
      supported.
    * all: IETF BCP 47/RFC 5646 language tags: Digital Cinema
      Naming Convention language codes that fall into the IETF BCP
      47 range of "private use" tags (`qaa`–`qtz`) are now
      replaced by their IETF BCP 47 equivalents during
      normalization (e.g. `QMS` → `cmn-Hans`).
    * all: added a new translation to Chinese Simplified
      (Singapore) by Dian Li.
    * mkvmerge, mkvpropedit: added a new command line option called
      `--enable-legacy-font-mime-types`. With this option on the
      two programs will use the same legacy MIME types for fonts
      whenever new attachments are added (both programs), when
      reading existing attachments (only `mkvmerge`) or when
      replacing existing ones (only `mkvpropedit`).
    * mkvmerge, mkvpropedit: IETF BCP 47/RFC 5646 language tags:
      added a command line option `--normalize-language-ietf
      <mode>` which turns on normalization of IETF BCP 47 language
      tags to either their canonical (mode `canonical`) or
      extended language subtags form (mode `extlang`) or turns it
      off (mode `off`). If the option isn't given, language tags
      will now be normalized to the canonical form.
    * MKVToolNix GUI: IETF BCP 47/RFC 5646 language tags: ISO
      639-3 and 639-5 languages will now be used by default.
    * MKVToolNix GUI: IETF BCP 47/RFC 5646 language tags: the
      language editor dialog will now show warnings in several
      cases: when deprecated tags are used; when the tag's
      canonical and/or extlang forms differ from the user input.
    * MKVToolNix GUI: IETF BCP 47/RFC 5646 language tags: the
      language editor now has a button to replace the current tag
      with a normalized form (canonical or extlang) if those
      differ from the current tag.
    * MKVToolNix GUI: IETF BCP 47/RFC 5646 language tags: added an
      option in the preferences to always normalize all language
      tags to their canonical or extlang forms or to turn
      normalization off. Can also be enabled from the language
      editor dialog.
    * MKVToolNix GUI: IETF BCP 47/RFC 5646 language tags: the
      language dialog now shows a warning if a variant is used
      with a prefix that isn't in the variant's list of suitable
      prefixes. It'll also say if the corresponding
      canonical/extlang forms would have a suitable prefix.
    * MKVToolNix GUI: IETF BCP 47/RFC 5646 language tags: the
      language dialog now shows a warning if a script is used with
      a language for which it should be suppressed.
    * MKVToolNix GUI: multiplexer: the track property group boxes
      in the scrollable pane are now collapsible & expandable,
      saving their state over restarts of the GUI. This is in
      preparation of adding many more track properties in future
      releases, allowing the user to hide parts they don't use all
      that often.
    * MKVToolNix GUI: multiplexer: if the option "use legacy font
      MIME types" is enabled in the preferences, the new command
      line option `--enable-legacy-font-mime-types` will be passed
      to `mkvmerge` in order to have it remap the MIME types of
      existing attachments, too.
    Bug fixes:
    * all: IETF BCP 47/RFC 5646 language tags: variants aren't
      validated wrt. to prefixes anymore as BCP 47 doesn't
      actually pose restrictions on them, saying only that
      prefixes "are suitable sequences" for use with the variants.
      What is now verified, though, is that no variant is used
      multiple times within the same language tag.
    * build system & MKVToolNix GUI: fixed detecting the presence
      of & the compilation with the multimedia module of Qt
      version 6.2.0 and newer.
    * MKVToolNix GUI: job queue: fixed compiling in the audio
      player code for the the "play audio" end-of-job action.
    * MKVToolNix GUI: multiplexer: recognizing added XML chapter,
      segment info or chapter files required the XML declaration &
      root node (e.g. `<?xml…?> … <Chapters>` for chapters) be
      located within the first 1 KB, which wasn't enough for files
      that contain a lot of comments at the start like the
      included `example-chapters-2.xml`. The detection range was
      extended to 10 KB.
    Build system changes:
    * The bundled `fmt` library was updated to v8.1.1.
    * The bundled `nlohmann-json` library was updated to v3.10.5.
    * The bundled `pugixml` library was updated to v1.12.1.
* Sun Mar 13 2022 Luigi Baldoni <aloisio@gmx.com>
  - Update to version 66.0.0
    New features and enhancements:
    * mkvpropedit: added a new option `--chapter-charset` allowing
      the user to specify the character set to use when reading
      the following chapter file.
    * MKVToolNix GUI: each language shortcut can now be associated
      with an optional track name that is set along with the
      language when the shortcut is used.
    Bug fixes:
    * mkvmerge: Ogg/OGM reader: mkvmerge will no longer abort with
      an exception when it encounters Vorbis comments that contain
      data that isn't valid UTF-8.
    * MKVToolNix GUI: multiplexer: fixed several issues with the
      tab order of elements in the "properties" pane and the
      "output" tab. Also fixed the language display widgets (e.g.
      "track language" in the "properties" pane) never receiving
      tab focus.
    * MKVToolNix GUI: multiplexer: the chapter name template will
      now be passed to `mkvmerge` if a chapter file is selected on
      the "output" tab.
* Sun Feb 06 2022 Luigi Baldoni <aloisio@gmx.com>
  - Update to version 65.0.0
    New features and enhancements:
    * mkvmerge: the options `--default-track` and `--forced-track`
      have been renamed to `--default-track-flag` and
      `--forced-display-flag` respectively
      for improved consistency with other option names & the
      wording used in the GUI. However, the old names will be
      supported and recognized
      indefinitely. What will remain unchanged is the property
      names for those flags in mkvmerge's identification output.
      Existing third-party programs will continue working as they
      are.
    * mkvmerge: added a new option `--track-enabled-flag` to set
      or unset the "track enabled" track header flag.
    * mkvmerge: MP4 reader: `mkvmerge` will now evaluate the
      `flags` field of the track header atom (`tkhd`) and set the
      track's "enabled" flag accordingly.
    * MKVToolNix GUI: multiplexer: added support for the "track
      enabled" track header flag.
    * MKVToolNix GUI: multiplexer, header editor: added several
      menu entries & keyboard shortcuts for toggling various track
      flags of the currently selected tracks, e.g. `Ctrl+Alt+F, D`
      (that's `Ctrl` and `Alt` with `F` simultaneously followed by
      `D` without any other key pressed) for toggling the "default
      track" flag.
    * MKVToolNix GUI: multiplexer, header editor: added menu
      entries & keyboard shortcuts for setting the language of the
      currently selected tracks to one from a configurable list of
      languages. The shortcuts used are `Ctrl+Alt+A, 1` through
      `Ctrl+Alt+A, 0` for the first ten entries of that list
      (that's `Ctrl` and `Alt` with `A` simultaneously followed by
      a digit without any other key pressed).
    * MKVToolNix GUI: chapter editor: if the user enters commas in
      start or end timestamps they will automatically be changed
      to points as the decimal separator, allowing for easier copy
      & paste from other programs/sources.
    * MKVToolNix: header editor: the selected track or attached
      file can now be moved up & down with the keyboard shortcuts
      `Ctrl+Up` & `Ctrl+Down` respectively.
    Bug fixes:
    * mkvmerge: Matroska reader: DVB subtitle tracks with a codec
      private data size of more than five bytes are accepted now,
      too.
* Mon Jan 10 2022 Guillaume GARDET <guillaume.gardet@opensuse.org>
  - Update _constraints to cover all architectures, not only ppc64
* Mon Dec 27 2021 Luigi Baldoni <aloisio@gmx.com>
  - Update to version 64.0.0
    New features and enhancements:
    * MKVToolNix GUI: language dialog: when the user switches
      between the two edit modes, the mode's corresponding first
      control is automatically focussed.
    Bug fixes:
    * all: language lists: the entries for "Ancient Greek (to
      1453)" and "Modern Greek (1453-)" have been renamed to
      "Greek (ancient, -1453)" and "Greek (modern, 1453-)"
      respectively in order to be easier to find.
    * mkvmerge: VobSub reader: files containing `id: --` lines to
      indicate that the track language isn't known were rejected
      by `mkvmerge`. Now they're accepted, and `und`
      (undetermined) is used as the language.
    * MKVToolNix GUI: chapter editor: the "Save to Matroska or
      WebM file" function was using the wrong standard file dialog
      (the "open file" one instead of "save"), leading to
      confusing button names.
    * MKVToolNix GUI: high DPI scaling: fixed the icons in the
      tool selector having the wrong size for scaling factors
      other than 100% or 200%.
    Build system changes:
    * The bundled `fmt` library was updated to v8.0.1.
    * The bundled `nlohmann-json` library was updated to v3.9.1.
    * The bundled `pugixml` library was updated to v1.11 revision
      6a76cac.
    * The bundled `utf8-cpp` library was updated to v3.2 revision
      b85efd6.
* Sun Nov 14 2021 Luigi Baldoni <aloisio@gmx.com>
  - Update to version 63.0.0
    New features and enhancements:
    * mkvmerge: AC-3 parser: E-AC-3 with BSID values > 10 and ≤ 15
      are recognized now, too.
    * mkvmerge: when using language codes for track selection
      (e.g. `-a und,en`) all tracks that do not have a language
      property (due to their container not providing one, e.g.
      AVIs) will be treated as if they did have one set to `und`
      ("undetermined") as that is the language the track will have
      in the Matroska file anyway. Before this change it wasn't
      possible to match such tracks via language codes.
    * MKVToolNix GUI: the spinner in the bottom right corner will
      now be hidden when no jobs are currently running.
    * MKVToolNix GUI: header editor: a new column has been added
      to the tree view showing the status of the "track enabled"
      flag. The information is also shown on the track overview
      page on the right.
    * MKVToolNix GUI: header editor: users can now reorder tracks
      by dragging & dropping.
    Bug fixes:
    * mkvmerge: AVI reader: fixed reading AVI files that contain
      `vprp` video properties header chunks; reading aborted too
      early.
* Sun Oct 10 2021 Luigi Baldoni <aloisio@gmx.com>
  - Update to version 62.0.0
    New features and enhancements:
    * all: IETF BCP 47/TFC 5646 language tags: all ISO 639
      languages are now available, even the ones that aren't of
      types "Constructed", "Living" or "Special".
    * mkvmerge, mkvpropedit: chapters: both programs will now
      write elements set to their default value, too (e.g. the
      legacy language element if it's set to `eng`). This is done
      to be more consistent with how MKVToolNix GUI writes chapters.
    * MKVToolNix GUI: multiplexer: when adding new files as
      attachments the GUI checks if there are other attachments with
      the same name. If so, the GUI would ask whether to skip the
      affected files or add them anyway. There's now an option in
      the preferences to always skip such files, and it's enabled
      by default.
    * MKVToolNix GUI: chapter editor: removed the support for
      explicitly setting the legacy country elements. Instead the
      legacy country elements are derived from the region parts of
      the IETF BCP 47 languages.
    Bug fixes:
    * mkvmerge: fixed a crash when splitting by chapters is
      enabled but there are no chapters at all.
    * mkvmerge: the error message when trying to split by a
      chapter number that doesn't exist contained the wrong
      number of chapters that actually do exist.
    * mkvmerge: AVC ES parser: fixed mkvmerge aborting due to
      uncaught exception when encountering bad SPS data.
    * mkvmerge: AVC/H.264 parser: re-added the hack `--engage
      all_i_slices_are_key_frames` which was accidentally removed
      in release v61.
    * mkvmerge: AVI reader: fixed a crash trying to allocate too
      big of a memory chunk due to an integer overflows in check
      conditions.
    * mkvmerge: HEVC ES parser: fixed another issue with frame type
      recognition. Certain frames were marked as B
      frames/discardable on the container level even though they
      could be reference pictures. Now only SLNR pictures
      (sub-layer non-reference) are marked that way.
    * mkvmerge: HEVC ES reader: improved file content detection
      for HEVC ES files with wrong file name extensions (e.g.
      `.mkv`), which fixes them being mis-detected as something
      else, e.g. DTS.
    * mkvmerge: HEVC ES parser: "end of sequence" NALUs are kept
      now, and no superfluous flushing will be done when one is
      found. This prevents splitting NALUs into two different
      Matroska blocks when they should really be part of a single
      one, also causing problems with erroneous timestamps. Mostly
      affects DoVi NALUs.
    * mkvmerge: Matroska reader, TrueHD: mkvmerge will now probe
      much more TrueHD frames trying to find the first sync frame.
      This fixes track detection in situations when a TrueHD
      doesn't start with a sync frame, e.g. when the source file's
      the result of splitting between sync frames.
    * mkvmerge, MKVToolNix GUI's chapter editor: IETF BCP 47/RFC
      5646 language tags: when reading chapters from MPLS playlist
      files, the `ChapLanguageIETF` element will now be set to the
      configured default chapter language, not just the legacy
      `ChapterLanguage` element.
    * mkvmerge, mkvpropedit, MKVToolNix GUI's chapter editor: IETF
      BCP 47 elements will now always be created before writing
      chapters unless IETF BCP 47 elements are disabled.
    * mkvmerge, mkvpropedit, MKVToolNix GUI's chapter editor: when
      a chapter display element contains legacy language & country
      elements but no IETF BCP 47 elements and IETF BCP 47 elements
      aren't disabled, the IETF BCP 47 elements created will
      contain the region from the legacy element.
    * mkvmerge, mkvpropedit, MKVToolNix GUI's chapter editor:
      Legacy country elements are now created when IETF BCP 47
      elements are present & contain a region code allowed in
      legacy country elements.
    Build system changes:
    * The `tools` sub-directory is now always built. The
      corresponding `configure` option `--with-tools` has been
      removed. The `install` target still doesn't install them,
      though.
  - Add tools subpackage
* Mon Aug 30 2021 Luigi Baldoni <aloisio@gmx.com>
  - Update to version 61.0.0
    New features and enhancements:
    * all: IETF BCP 47/RFC 5646 language tags: implemented support
      for officially registered IANA language tag extensions.
    * mkvmerge: track selection: when using language tags for
      selecting which tracks to keep, mkvmerge will now use
      component-based language tag matching instead of comparing
      them verbatim. This means that only those components
      (language, region etc.) the user specified will be required
      to exist and be equal. For example, if a file contains three
      subtitle tracks with languages `es` (generic Spanish),
      `es-MX` (Spanish as spoken in Mexico) and `es-ES` (Spanish as
      spoken in Spain), the user can use `--stracks es` to match
      all three tracks or be more specific with e.g. `--stracks
      es-MX` which would only match one track. Similarly inverting
      the selection with e.g. `--stracks !es` would get rid of all
      three tracks, not just the one for the generic Spanish.
    * MKVToolNix GUI: multiplexer: deriving track languages from
      file names: the GUI can now detect full BCP 47/RFC 5646
      language tags in file names.
    * MKVToolNix GUI: multiplexer: deriving track languages from
      file names: the default list of boundary characters now
      includes `-`.
    * MKVToolNix GUI: multiplexer: the GUI now defaults to the
      "lower" process priority setting for new installations in
      order to leave more room for other applications, especially
      interactive ones. Up to and including v59 the default was
      the "normal" process priority. v60 changed that to "lowest",
      which turned out to be much slower on Windows for no real
      gain over "lower". The setting will be auto-corrected by the
      GUI if the settings file were saved last with a version
      between v60.0.0.0 & v60.0.0.17 & "lowest" & it is still set
      to "lowest".
    * HEVC dumper development tool: the tool has been renamed to
      `xvc_dump` and extended to be able to dump AVC/H.264
      bitstreams, too. It now also detects the type of bitstream
      framing (ISO 14496-15 vs. ITU-T H.264/H.265 Annex B).
    Bug fixes:
    * all: IETF BCP 47/RFC 5646 language tags: fixed a corner case
      of wrongfully allowing scripts/variants not listed in any of
      the entries in the prefix list when the prefix list contains
      prefixes restricting scripts/variants and a prefix solely
      with the language at the same time (example: the variant
      `ekavsk` with its prefixes `sr`, `sr-Cyrl` and `sr-Latn`
      where e.g. `sr-ekavsk` and `sr-Cyrl-ekavsk` should be
      allowed but not `sr-Bali-ekavsk`).
    * mkvmerge: HEVC/H.265: the frame type of B frames was often
      wrongfully signalled as P frames instead, both with
      `BlockGroup` (missing second references) and `SimpleBlock`
      ("discardable" flag not set) elements.
    * mkvmerge: SSA/ASS packetizer: the frame numbers will now be
      re-calculated when appending SSA/ASS tracks so that frame
      numbers of appended tracks are always strictly higher than
      frame numbers of the track they're appended to.
    * mkvmerge, MKVToolNix GUI's chapter editor: BCP 47/RFC 5646
      language tags: when BCP 47 language tags are used with a
      language code that isn't part of ISO 639-2, the programs
      will now write a legacy language element set to `und`
      ("undetermined") instead of not writing such an element at
      all or writing one with an invalid code.
    * mkvmerge, MKVToolNix GUI's chapter editor: BCP 47/RFC 5646
      language tags: the programs will ensure that the legacy and
      IETF language elements written will be unique within the
      scope of the same "chapter display" element.
    * mkvinfo, MKVToolNix GUI's info tool: in summary mode the
      frame type was reported wrong for `BlockGroup` elements in
      which the `ReferenceBlock` elements were located behind the
      `Block` element.
    Build system changes:
    * all: `std::codecvt_utf8` is now used instead of Boost's
      `utf8_codecvt_facet`. The bundled copy the latter in
      `lib/boost` has therefore been removed.
  - Drop mkvtoolnix-use-system-boost.patch (no longer necessary)
* Sat Jul 31 2021 Luigi Baldoni <aloisio@gmx.com>
  - Update to version 60.0.0
    New features and enhancements:
    * all: IETF BCP 47/RFC 5646 language tags: added support for
      language families from ISO 639-5 that aren't part of 639-2.
    * all: IETF BCP 47/RFC 5646 language tags: implemented support
      for Alpha 2 country codes of the "user-defined" category:
      `AA`, `QM`–`QZ`, `XA`–`XZ` and `ZZ`.
    * all: IETF BCP 47/RFC 5646 language tags: updated the various
      lists of valid subtags from the official specs.
    * MKVToolNix GUI: multiplexer: pressing the keyboard shortcut
      for the track's "Language" label (Alt+L for English) will
      now open the language dialog.
    * MKVToolNix GUI: multiplexer: added an option in the
      preferences for turning off the colored boxes indicating
      which file each track belongs to.
    Bug fixes:
    * all: IETF BCP 47/RFC 5646 language tags: fixed validating
      extended language & variant subtags against their allowed
      prefixes (e.g. a valid tag with a country code as in
      `de-CH-1996` is recognized as valid while two generally
      known variants that aren't allowed together as in
    `de-1901-1996` is recognized as invalid).
    * all: IETF BCP 47/RFC 5646 language tags: when looking up a
      language for a two- or three-letter code, the programs will
      no longer compare that code with language names as that was
      unintended, ambiguous (e.g. the code "Ga" could be
      interpreted as the 639-2 alpha-2 code for "Irish" or as the
      name of the language called "Ga") and only worked with
      languages whose name was at most three letters long.
    * mkvmerge: HEVC/H.265: appending Matroska files with HEVC
      tracks might lead to the loss of the first couple of frames
      from each of the second and all following files.
    * mkvmerge, mkvextract: HEVC/H.265 parser: fixed the programs
      aborting when parsing VPS or SPS NALUs with invalid content
      due to unhandled exceptions.
    * MKVToolNix GUI: multiplexer: when the option "use legacy
      MIME types for font attachments" is enabled, the GUI will
      now use `application/x-truetype-font` for font collection
      files.
    * MKVToolNix GUI: multiplexer: when adding multiple files at
      once, the GUI will sort file names with numbers the way a
      human would expect it to. For example, `1.mp4`, `9.aac`,
      `10.srt`, `11.srt` are now sorted exactly that order instead
      of `1.mp4`, `10.srt`, `11.srt`, `9.aac`.
    * MKVToolNix GUI: header editor: the header editor will now
      honor the "use legacy MIME types when adding font
      attachments" setting when adding new attachments.
* Sat Jul 10 2021 Luigi Baldoni <aloisio@gmx.com>
  - Update to version 59.0.0
    New features and enhancements:
    * mkvmerge: WebVTT parser: the parser now follows the specs'
      rules for parsing timestamps more closely by being more
      lenient: it allows arbitrary number of spaces & tabs at the
      start of the line & around the arrow; it allows any number
      of digits for the hours.
    * MKVToolNix GUI: multiplexer: when adding a Blu-ray playlist
      without scanning for other playlists the GUI will now look
      for disc library information & let the user select which one
      to use if there's more than one entry.
    * MKVToolNix GUI: multiplexer: added an option for sorting
      files & tracks by track types when adding them to multiplex
      settings. The order is: video first followed by audio,
      subtitles and other types. Files & tracks can still be
      reordered manually later. The option is enabled by default &
      can be found in the preferences → "Multiplexer" page →
      "Adding files" section.
    * MKVToolNix GUI: multiplexer: added an option for recognizing
      file name sequences such as `movie.001.mp4`, `movie.002.mp4`,
      `movie.003.mp4` when adding multiple files at once. If a
      sequence is detected, the only first file will be added while
      the second and following file names will be appended to the
      first one. The option is enabled by default & can be found
      in the preferences → "Multiplexer" page → "Adding files"
      section.
    * MKVToolNix GUI: multiplexer: added small colored boxes for
      each file & track in order to indicate from which file each
      track is read. The colors used can be configured in the
      preferences → "Multiplexer" page → "File & track colors"
      section.
    Bug fixes:
    * build system: fixed compilation with fmt v8. Fixes #3151.
    * mkvmerge: SRT subtitle reader: characters that aren't valid
      according to the assumed encoding of the file will now be
      replaced by the Unicode "Replacement Character" U+FFFD
      instead of keeping the invalid characters, potentially
      violating the Matroska specs.
    * mkvmerge: WebVTT parser: the parser now accepts timestamps
      with hours larger than 99.
    * mkvextract: TTA extraction, only on Windows: fixed removing
      the temporary file created during extraction.
    * mkvmerge, mkvpropedit, MKVToolNix GUI's multiplexer & header
      editor: MIME type detection is now done using Qt instead of
      the `magic` library. The main impact is the MIME types of
      TrueType & OpenType fonts are now detected correctly.
    * MKVToolNix GUI: multiplexer: when adding files to the
      multiplexer by running the GUI's executable with file names
      as command line arguments, the source directory will be
      remembered as the "last open directory" again, causing
      subsequent uses of the "open file" dialog to start in the
      same directory.
    * MKVToolNix GUI: multiplexer: the "default track flag" column
      in the track list was missing its icons. Additionally it
      contained text even for things that aren't regular tracks
      and therefore do not actually have that flag (e.g. chapters
      or tags).
    * MKVToolNix GUI: multiplexer: the default for the dialog
      asking the user what to do with dragged & dropped files if
      they've never seen the dialog is back to adding the files to
      the current multiplex settings instead of "add as additional
      parts" which was an unintentional default.
    * MKVToolNix GUI: multiplexer: the "show command line" dialog
      will now always use backward slashes for the "Windows
      (cmd.exe)" mode and forward slashes for the "Linux/Unix
      shells" mode, regardless of the operating system it's
      currently running on.
    Build system changes:
    * The Qt library is now required for building all
      applications, even the command-line ones, as they use Qt's
      MIME type detection capabilities. In turn this means that
      you cannot disable the Qt usage anymore; either Qt5 or Qt 6
      is required. You can still chose not to build MKVToolNix
      GUI, though. A new option has been added to `configure`
      for this purpose: `--disable-gui`.
    * The `gmp` library is now required.
    * The `magic` library is not used anymore.
    * The `PCRE2` & `JPCRE2` libraries are not used anymore. The
      bundled version of `JPCRE2` was removed.
    * Boost's "rational" library is not used anymore.
    * `configure`: the option `--enable-appimage` has been
      removed. The location of the relevant directories within an
      AppImage is now detected automatically.
    * The bundled `fmt` library was updated to v8.0.0.
  - Use system version of utfcpp
* Sun Jun 13 2021 Luigi Baldoni <aloisio@gmx.com>
  - Update to version 58.0.0
    New features and enhancements:
    * mkvmerge, MKVToolNix GUI's multiplexer: the handling of the
      "default track" flag has been changed to match the recent
      changes to the Matroska specifications. The new semantics
      are that if it is set, it is supposed to signal to the
      player that this track is eligible for being played by
      default, potentially taking other factors such as user
      preferences regarding languages into account.
      This implies that more than one track of each type can have
      this flag set. For example, a Blu-ray disc with three audio
      tracks might have the main audio in both English and
      Japanese, whereas the third audio track contains the
      director's comments. In such a case the first two tracks
      should have the "default track" flag set, the third one
      shouldn't.
      Earlier `mkvmerge` was enforcing that only one track of each
      type could have the flag set. This restriction has been
      removed, both in `mkvmerge` and in the GUI's multiplexer.
      `mkvpropedit` and the GUI's header editor are unaffected as
      they've always allowed to set the flag on as many tracks as
      the user wanted.
    * mkvmerge: AVC/H.264 & HEVC/H.265 identification: added the
      stream's pixel dimensions (AVC only; were present for HEVC
      already) & default duration.
    * mkvmerge, mkvextract: HEVC/H.265: added support for reading
      single-layer Dolby Vision from Annex B type bitstreams
      (elementary streams, MPEG transport streams).
    * mkvinfo: the option `-X`/`--full-hexdump` now affects all
      binary elements, not just the frame data in `SimpleBlock`
      and `BlockGroup` elements.
    * MKVToolNix GUI: multiplexer: the "delay" and "sync" options
      can now be used for chapters in source files, too.
    * MKVToolNix GUI: when moving list entries up & down with the
      optional buttons or the keyboard shortcuts (instead of using
      drag & drop), the GUI ensures that the top-most selected
      entry remains visible after the move.
    * MKVToolNix GUI: added an option in the preference to use
      legacy MIME types for font attachments instead of the current
      standard ones (e.g. 'application/x-truetype-font' instead of
      'font/sfnt' and 'font/ttf').
    Bug fixes:
    * build system: fixed filtering out optimization options when
      compiling the file `iso639_language_list.cpp` (before only
      numeric optimization levels were filtered out and only if it
      wasn't the last option in the list of flags).
    * build system: when libmagic was detected via `pkg-config`,
      MKVToolNix was actually compiled without support for
      libmagic due to a preprocessor symbol not being defined.
    * mkvmerge: MP4 reader: fixed an issue with timestamps
      overflowing when the file's or the track's time scale is
      large.
    * mkvmerge, mkvextract: fixed key frame handling for
      `BlockGroup` elements with a forward reference but no
      backward references.
    * mkvmerge, mkvpropedit, MKVToolNix GUI's chapter editor: the
      programs will no longer omit writing mandatory elements set
      to their default value if other elements of the same type
      are present in the same master. This affects mostly the
      "chapter language" element which may occur multiple times
      within the same "chapter display" master. If it does occur
      multiple times and one of them is set to "English" (which is
      that element's default value), that element will now be
      written, too.
    * mkvmerge, mkvpropedit, MKVToolNix GUI's chapter editor: when
      parsing chapter files IETF & legacy language elements as
      well as legacy country elements will now be properly
      generated depending on which exist already, especially when
      there's more than one language and/or country element
      in a "chapter display" element.
    * mkvmerge, mkvpropedit, MKVToolNix GUI's chapter editor:
      fixed reading OGM-style chapter files with timestamps that
      don't have exactly three decimal places. Any number of
      decimal places between one and nine is now supported for
      nanosecond precision.
    * MKVToolNix GUI: chapter editor: added/fixed support for
      "chapter display" elements with multiple languages or
      countries.
    Build system changes:
    * Qt 6: added support for building with Qt 6. `configure` will
      look for Qt 6 first and only continue looking for Qt 5 if Qt
      6 isn't found or disabled via `--disable-qt6`.
      Qt 6 detection works by first looking for the `qmake6`
      binary. Its location can be specified with the
      `--with-qmake6=…` option.
      All other Qt 6 related facts (such as compiler & linker
      flags or the position of the other required tools such as
      `lconvert`, `moc`, `rcc` and `uic`) will be derived from
      the output generated by `qmake6`.
      Note that at this point Qt 6 is not yet supported for the
      cross-compilation  build to Windows, nor is a static Qt 6
      build supported yet. Note that the command line options
      `--enable-static-qt`, `--with-qt-pkg-config-modules` and
      `--without-qt-pkg-config` only apply to the Qt 5 and have
      no effect on Qt 6.
    * Qt 5: the options for specifying the position of the tools
      (`--with-moc=…`,`--with-rcc=…` and `--with-uic=…`) have been
      removed. Their position will now be derived from the output
      generated by `qmake`.
    * `configure`: completely disabling the GUI now requires
      passing both `--disable-qt6` and `--disable-qt` options.
    * Boost's multi-precision library is now required.
    * Boost v1.66 or newer is now required.
* Sat May 22 2021 Luigi Baldoni <aloisio@gmx.com>
  - Up date to version 57.0.0
    New features and enhancements:
    * mkvmerge: MP4 reader: added support for reading Dolby Vision
      from MP4 files (FourCCs `dvh1` and `dvhe`; configuration
      records `dvcC`, `dvvC` and `hvcE` will be converted into
      block addition mappings).
    * mkvmerge: SRT subtitles: mkvmerge now accepts empty text
      files with the extension `.srt` as SRT subtitle files,
      enabling the creation of empty SRT tracks.
    * mkvmerge, mkvextract: HEVC/H.265: access unit delimiter
      NALUs will no longer be discarded, neither during muxing nor
      during extraction.
    * MKVToolNix GUI: preferences: switched the order & wording of
      controls in the "enabling items" panel to make it clearer
      that certain controls define exceptions.
    Bug fixes:
    * mkvmerge: HEVC/H.265 parser: several NALU types, notably the
      Dolby Vision-specific NALUs ("unspecified 62" and
      "unspecified 63") and suffix SEI NALUs, are now stored with
      the frame they belong to instead of with the next frame.
    * mkvmerge: HEVC/H.265 packetizer: fixed setting the track's
      default duration when reading HEVC/H.265 from Matroska files
      that don't have a default duration set.
    * mkvmerge: HEVC/H.265 packetizer: fixed the calculation of
      the duration of frames so that `SimpleBlock` elements can be
      used again instead of `BlockGroups` with `BlockDuration`
      elements.
    * mkvmerge, mkvextract: HEVC/H.265 parser: fixed issues with
      ordering & duplication of certain NALUs (parameter set &
      prefix SEI NALUs).
    * MKVToolNix GUI: multiplexer: when dragging & dropping files
      to the multiplexer, the source directory will be remembered
      as the "last open directory" again, causing subsequent uses
      of the "open file" dialog to start in the same directory.
    * mkvinfo: fixed the position of frames in block groups
      containing "block duration" elements in summary mode (e.g.
      for subtitle tracks).
    Build system changes:
    * `configure` will now try to detect `libmagic` via
      `pkg-config` and fall back to including & linking directly if
      it cannot be found via `pkg-config`.
* Fri Apr 09 2021 aloisio@gmx.com
  - Update to version version 56.1.0
    New features and enhancements:
    * mkvmerge: AAC: added support for LOAS/LATM files with
      channel configuration indexes 9–21 (e.g. channel count 22.2
      for index 13) according to Rec. ITU-R BS.1196-7 & ISO/IEC
      23008-3:2019.
    Bug fixes:
    * mkvmerge: HEVC/H.265 parser: fixed invalid memory access
      that could happen when reading certain types of HEVC data
      (e.g. with changing parameter sets mid-stream) from certain
      containers (e.g. Matroska). This bug was introduced in
      release 56.0.0.
    * mkvextract: AAC: mkvextract will now abort with an useful
      error message when the user tries to extract a track whose
      'audio-specific config' element in `CodecPrivate` signals a
      number of channels of 7 or greater than 8 as that isn't
      supported by the ADTS format.
    Build system changes:
    * configure: the `--enable-ubsan` option hasn't actually
      enabled anything since release 39.0.0.
* Mon Apr 05 2021 Luigi Baldoni <aloisio@gmx.com>
  - Update to version 56.0.0
    New features and enhancements:
    * mkvmerge, mkvpropedit: tags: the programs will no longer
      write tag elements that are mandatory and set to their
      default value (e.g. "tag language" set to `und` =
      undetermined).
    * mkvmerge, mkvpropedit, MKVToolNix GUI chapter editor:
      chapters: the programs will no longer write chapter elements
      that are mandatory and set to their default value (e.g.
      "chapter language" set to `eng` = English or "Chapter flag
      enabled" = 1).
    * mkvextract: chapters: mkvextract will no longer add a
      `ChapterLanguage` element set to `eng` to the generated XML
      content if the source file doesn't contain such an element.
    * MKVToolNix GUI: multiplexer: when using the "tab widget
      below the files & tracks" layout option for the track
      properties the elements in the "general options" tab will
      use six rows à four columns instead of twelve rows à two
      columns, greatly reducing the required height.
    Bug fixes:
    * mkvmerge: AAC reader: fixed mkvmerge aborting to read AAC
      files bigger than 2 GB with a message about not being able
      to allocate memory.
    * mkvmerge: chapters: `ChapLanguageIETF` elements were still
      created when the option `--disable-language-ietf` was given
      after an option leading to the creation of chapters. Now the
      position doesn't matter anymore.
    * mkvmerge: chapters: when the option
      `--disable-language-ietf` is used, `ChapLanguageIETF`
      elements won't be written even when sources are read
      (Matroska files or XML chapters files) that do contain those
      elements.
    * mkvmerge: tags: when the option `--disable-language-ietf` is
      used, `TagLanguageIETF` elements won't be written.
    * mkvmerge: tags: mkvmerge will no longer write language
      elements for the track statistics tags it creates, making
      the effective language "undetermined" due to `und` being the
      default value for the legacy tag language element.
    * mkvmerge: tags: the XML tag parser will now validate all
      `<Simple>` children of `<Tag>` elements, not just the first
      for each `<Tag>`.
    * mkvmerge: tags: the XML tag parser now uses the
      spec-compliant `und` ("undetermined") as the default
      language for `<Simple>` tags instead of `eng`.
    * mkvmerge, mkvpropedit: tags: mkvmerge will no longer set the
      "target type" for track statistics tags (earlier it used
      `MOVIE`). The "target type value" will still be set to `50`.
    * mkvmerge, mkvextract: HEVC/H.265: both programs will now
      normalize the placement of VPS, SPS and PPS NALUs. Each key
      frame is prefixed with exactly one copy of the currently
      active parameter sets. This fixes certain classes of bugs
      related to splitting/appending.
    * mkvinfo: when compiled with newer versions of the `fmt`
      library, certain numbers were not output correctly (e.g. a
      track's audio sampling frequency of 48000 might be output as
      48).
    * MKVToolNix GUI: multiplexer: deriving the track language
      from the file name will match languages case insensitively
      again (like versions prior to v55).
    * MKVToolNix GUI: multiplexer: under certain circumstances
      keyboard shortcuts such as `Ctrl+W` for closing the active
      tab or `Ctrl+R` for starting to multiplex ceased to work
      until the user did certain other things (such as switching
      to a different tool & back to the multiplexer or opening the
      multiplexer menu). This started with v54.
    * MKVToolNix GUI: chapter editor: the editor will no longer
      create empty `ChapterCountry` elements when adding a chapter
      name with no default country selected in the preferences.
    Build system changes:
    * The bundled `fmt` library was updated to v7.1.3.
* Sat Mar 06 2021 Luigi Baldoni <aloisio@gmx.com>
  - Update to version 55.0.0
    Bug fixes:
    * MKVToolNix GUI: multiplexer: the user can now configure what
      to do when using the "Add source files" button independently
      of the setting for what happens when files are dragged &
      dropped onto the GUI. The same options are available, but
      they're distinct settings, allowing for different use cases.
    * MKVToolNix GUI: multiplexer: deriving the track language
      from file names doesn't use one big regular expression of all
      enabled languages anymore. Instead, the file name is split
      into parts on a list of characters (such as `.` or
      `(` and `)`; configurable in the preferences). This prevents
      the regular expression becoming too big for the regular
      expression library to handle when many languages are enabled.
    * MKVToolNix GUI: preferences: the language lists for
      "deriving track languages" and "enabling items by language"
      always included all the ISO 639-3 languages, even if those
      weren't enabled in the "often-used languages" pane.
    Other changes:
    * mkvmerge, MKVToolNix GUI multiplexer: the functionality for
      changing the length of the NALU "size" field for AVC/H.264
      and HEVC/H.265 tracks has been removed. The corresponding
      command-line option will continue to be recognized by
      mkvmerge as not to break existing third-party applications,
      but it won't actually do anything.
* Fri Feb 26 2021 Luigi Baldoni <aloisio@gmx.com>
  - Update to version  54.0.0
    New features and enhancements:
    * mkvmerge: added support for using ISO 639-3 language codes in
      IETF BF47 language tags.
    * mkvmerge: AC-3 parser: added support for byte-swapped AC-3
      data.
    * mkvmerge: Matroska reader: for audio tracks that have the bit
      depth track header set mkvmerge will now keep that header
      even for codecs that don't require it for decoding.
    * mkvmerge: MPEG transport stream reader, PCM audio tracks:
      mkvmerge will now re-order the channels for 5.1, 7.0 and 7.1
      channel tracks from the Blu-ray layout to the
      WAVEFORMATEXTENSIBLE layout expected in Matroska.
    * mkvmerge, mkvinfo, mkvpropedit, MKVToolNix GUI: added support
      for the following new track header elements: "hearing impaired"
      flag, "visual impaired" flag, "text descriptions" flag,
      "original" flag, "commentary" flag.
    * MKVToolNix GUI: added support for using ISO 639-3 language
      codes in IETF BF47 language tags. As there are several
      thousand of them, they're deactivated by default and must be
      activated in the preferences ("GUI" → "Often used selections"
      → "Languages").
    * MKVToolNix GUI: multiplexer: when adding Blu-rays the user
      can select multiple playlists to add simultaneously in the
      "select playlist to add" dialog.
    * MKVToolNix GUI: multiplexer: the file name extensions "eb3"
      and "ec3" were added for Dolby Digital Plus & "mpl" for Dolby
      TrueHD in the file dialogs.
    * MKVToolNix GUI: multiplexer: when adding multiple files the
      dialog asking the user what to do with them has gained a new
      checkbox. If enabled, all files containing at least one video
      track will always be placed in newly created multiplex
      setting.
    * MKVToolNix GUI: multiplexer: added a menu entry in the
      "Multiplexer" for adding all files that are currently in the
      clipboard.
    Bug fixes:
    * mkvextract: AAC: fixed wrong channel mask field in the ADTS
      headers for 7.1 channel layouts.
    * mkvextract: h.265/HEVC extraction: if the first frame starts
      with the parameter sets (SPS, PPS & VPS), the ones from
      CodecPrivate aren't written and the ones from the first frame
      are kept.
    * mkvmerge: fixed the calculation of chapter timestamps read
      from NTSC DVDs.
    * MKVToolNix GUI: IETF BCP 47 language widget: the language
      combo box will now always contain the language code the user
      enters in the free-form field, even if it isn't in the list of
      often-used languages the user configured in the preferences.
    * MKVToolNix GUI: multiplexer: when browsing for the
      destination file name the default directory is now chosen
      according to the preferences regarding how the destination
      file name should be formed. For example, if the policy is
      set to "fixed output directory" then that output directory
      will be the one initially set when the directory selection
      dialog is opened.
    * MKVToolNix GUI: multiplexer: fixed the removal of appended
      source files if the "delete source files" end-of-job action
      is enabled.
    * MKVToolNix GUI: chapter editor: when importing chapters from
      DVDs the IETF BCP 47 language elements will be set, too, not
      just the legacy language elements.
    Build system changes:
    * libEBML v1.4.2 and libMatroska v1.6.3 are now required. The
      optional, bundled copies of both libraries have been updated
      to those versions. This bump in requirements fixes several
      heap overflow bugs in libEBML.
    * MKVToolNix is now using the C++17 library feature "file
      system library" instead of Boost's "file system" and "system"
      libraries. For the GNU Compiler Collection (gcc) libstdc++
      this means v8 or newer is required; for clang's libc++ it
      means v7 or newer.
* Sat Jan 30 2021 Luigi Baldoni <aloisio@gmx.com>
  - Update to version 53.0.0
    New features and enhancements:
    * mkvmerge: AVI reader: added support for reading the video
      aspect ratio from the video properties header (`vprp` chunk)
      if present and setting the display dimensions accordingly.
    * mkvmerge: MP4 reader: for h.264/AVC tracks that don't have an
      `AVCConfigurationBox` (`avcC` atom) in their sample
      description (`stsd`) atom or whose `avcC` atom contains no
      content `mkvmerge` will now re-derive the
      `AVCConfigurationBox` from the bitstream.
    * mkvextract: mkvextract will now check if any of the
      destination file names is the same as the source file name
      and abort with an error if that's the case.
    * MKVToolNix GUI: when querying the user for a file name for
      saving things (e.g. multiplexer settings or an attachment in
      the header editor), the automatically suggested file name
      will now be based on the situation-specific file names (e.g.
      the destination file name for multiplexer settings or the
      attachment's name when saving an attachment in the header
      editor) instead of the directory's name.
    * MKVToolNix GUI: multiplexer: when deriving track languages
      from file names the GUI will now select the right-most match
      instead of the left-most one. For example,
      "La.vie.en.rose.(fr).srt" will now be detected as French (fr)
      instead of English (en).
    * MKVToolNix GUI: preferences: the items in the "pre-defined
      …" lists can now be renamed by double-clicking with the
      mouse or pressing the F2 key.
    Bug fixes:
    * mkvmerge: stretching chapter timestamps with
      `--chapter-sync` now works correctly with floating point
      values including fractions of floating point numbers (e.g.
      `12.3/45.67`). The tooltips in the GUI have been adjusted
      accordingly.
    * mkvmerge: MPEG 1/2 video handling: the "default duration"
      header field was often half the value it actually should be,
      resulting in all video frames having an explicit block
      duration with the correct value.
    * mkvmerge: MPEG 1/2 video handling: the data stored in `Codec
      private` and `Codec state` doesn't contain extensions other
      than sequence & sequence display extensions anymore.
    * mkvmerge: tag handling: when remuxing a Matroska file with
      the `--no-track-tags`, existing `SOURCE_ID` track tags are
      now skipped, too.
    * MKVToolNix GUI: multiplexer: the drop-down boxes with
      pre-defined track names now follow the order set in the
      preferences instead of sorting the entries alphabetically.
* Tue Jan 05 2021 aloisio@gmx.com
  - Update to version 52.0.0
    New features and enhancements:
    * MKVToolNix GUI: job queue: the maximum number of jobs to run
      concurrently can now be increased in the preferences. The
      default remains at 1.
    * MKVToolNix GUI: the GUI will now add a context-specific
      default extension to file names selected for saving on
      platforms that don't add one itself (e.g. GNOME). For
      example, when saving multiplexer settings the extension
      `.mtxcfg` will be added.
    * MKVToolNix GUI: added an option to the preferences for the
      window to stay on top of other windows.
    Bug fixes:
    * mkvextract: h.265/HEVC extraction: the code for skipping
      extraction of prefix SEI NALUs in the first frame was
      skipping two bytes too few, resulting in broken processing
      of all following bytes.
    * libEBML: the optional, bundled version of libEBML was
      updated to v1.4.1.
    Build system changes:
    * libEBML v1.4.1 is now required due to a bug in libEBML that
      caused pointers to just-freed memory being returned to the
      caller under certain invalid data constellations, causing
      use-after-free errors in all of MKVToolNix's programs.
* Sun Oct 04 2020 Luigi Baldoni <aloisio@gmx.com>
  - Update to version 51.0.0
    New features and enhancements:
    * mkvmerge, mkvpropedit, MKVToolNix GUI: IETF BCP 47 language
      tags: added missing support for UN M.49 regions for which
      there are no corresponding ISO 3166 alpha codes. This
      enables language tags such as `es-419` = Spanish in
      Latin America and the Caribbean.
    * MKVToolNix GUI: IETF BCP 47 language tags: the text in the
      widget displaying the current language & the corresponding
      edit button is now displayed like a link (depending on the
      theme: different color & underlined), making it clearer
      that not just the edit button can be clicked but the text,
      too.
    Bug fixes:
    * mkvmerge: AV1 parser: fixed mkvmerge crashing after uncaught
      exceptions due to certain data conditions. Found by fuzzying.
    * mkvmerge: AV1 packetizer: the duration of frames wasn't set
      properly. When appending AV1 IVF or OBU files this meant that
      the last frame of the Nth file and the first frame of file
      N+1 had the same timestamp.
    * mkvmerge: DTS reader: fixed handling of buffers with an odd
      length when byte-swapped DTS is detected so that mkvmerge
      doesn't abort with a failed assertion. Found by fuzzying.
    * mkvmerge: h.264/AVC and h.265/HEVC elementary stream
      readers: mkvmerge will no longer claim to recognize data
      that looks like AVC or HEVC but with invalid video
      width/height values as that lead to failed assertions in
      libEBML later. Found by fuzzying.
    * mkvmerge: h.265/HEVC parser: fixed mkvmerge aborting after
      uncaught exceptions due to certain data constellations found
      by fuzzying.
    * mkvmerge: IVF reader: fixed mkvmerge crashing with a
      "division by zero" error due to certain data conditions.
      Found by fuzzying.
    * mkvmerge: fixed mkvmerge aborting with a "division by zero"
      error due to the timestamp scaling factor being 0 after
      handling certain data constellations. Found by fuzzying.
    * mkvmerge: track statistics: fixed a "division by zero" error
      when the content's shorter than 1ms. Found by fuzzying.
    * mkvmerge, mkvinfo, mkvextract, mkvpropedit: Matroska access
      class: fixed an invalid memory access under certain data
      conditions. Found by fuzzying.
    * MKVToolNix GIU: IETF BCP 47/RFC 5646 language tags: the GUI
      will no longer open the language dialog when clicking on a
      disabled language display widget.
    * MKVToolNix GUI: IETF BCP 47 language tags: the "variants"
      combo-boxes were not populated even when the language tag was
      valid and contained at a variant.
    * MKVToolNix GUI: IETF BCP 47 language tags: when no language
      is selected, at least one of the other components (extended
      subtags, region, or variants) has something selected and
      "private use" is not empty, the GUI would claim this to be a
      valid tag, which it isn't.
    * MKVToolNix GUI: multiplexer: when the tracks/chapters/tags
      selection changes from "at least one entry selected" to "no
      entry selected", the input controls will be reset to their
      default state and not just disabled.
    Build system changes:
    * `configure` now checks for the presence of the a system-wide
      installed copy of the JPCRE2 C++ wrapper library for the
      PCRE2 library and uses that if it's new enough (at least
      v10.32.1). If not, the bundled version will be used as a
      fallback.
* Sun Sep 06 2020 aloisio@gmx.com
  - Update to version 50.0.0
    New feature: IETF BCP 47 language tags:
    * I've written up a [nice FAQ
      https://gitlab.com/mbunkus/mkvtoolnix/-/wikis/Languages-in-Matroska-and-MKVToolNix
      about the switch to using IETF BCP 47 language tags, how
      they interact with legacy language elements, how the programs
      actually behave and how to disable their use if necessary.
    * mkvmerge: IETF BCP 47/RFC 5646 language tags: mkvmerge will
      now accept full BCP 47 language tags for all options taking
      a language. mkvmerge will always write "LanguageIETF" track
      header elements. If the language tag contains a valid ISO
      639-2 language code it will also set the legacy "Language"
      track header element to the included ISO 639-2 code.
    * mkvmerge: IETF BCP 47/RFC 5646 language tags: if present the
      "LanguageIETF" track header element will be reported as the
      `language_ietf` property in JSON identification mode.
    * mkvmerge: IETF BCP 47/RFC 5646 language tags in chapters:
      mkvmerge will now write "ChapLanguageIETF" elements when
      creating chapter atoms, either when reading the simple
      chapter format or when generating
      chapters due to the `--generate-chapters` command line
      option.
    * mkvmerge: IETF BCP 47/RFC 5646 language tags in tags:
      mkvmerge will now write "TagLanguageIETF" elements when
      creating "simple tag" elements, either when reading tag XML
      files or when generating them.
    * mkvmerge: IETF BCP 47/RFC 5646 language tags: added an option
      `--disable-language-ietf` that causes mkvmerge to only write
      the legacy language elements.
    * mkvmerge, mkvpropedit, MKVToolNix GUI's chapter editor: IETF
      BCP 47/RFC 5646 language tags in chapters: when reading XML
      chapter files the programs will now add "ChapLanguageIETF"
      elements for atoms that don't contain them. The values are
      derived from existing "ChapterLanguage" elements.
    * mkvpropedit: IETF BCP 47/RFC 5646 language tags:
      setting/deleting the track language now acts on both the old
      language element as well as the "LanguageIETF" track header
      element.
    * mkvpropedit: IETF BCP 47/RFC 5646 language tags: added an
      option `--disable-language-ietf` that causes mkvpropedit to
      apply changes to the `language` track header property only
      to the legacy language track header element.
    * mkvinfo: IETF BCP 47/RFC 5646 language tags: added support
      for the "LanguageIETF" track header element.
    * MKVToolNix GUI: multiplexer: added full support for IETF BCP
      47/RFC 5646 language tags for both track and chapter
      languages.
    * MKVToolNix GUI: chapter: added full support for IETF BCP
      47/RFC 5646 language tags for chapter languages.
    * MKVToolNix GUI: header editor: added full support for IETF
      BCP 47/RFC 5646 language tags for track header languages.
      The header editor allows editing of the legacy language
      elements and the IETF BCP 47 language elements independent
      of each other.
    Other new features and enhancements:
    * mkvmerge: the chapter generation mode `when-appending` now
      also works with the splitting modes `parts:` &
      `parts-frames:` when using the `…,+…` syntax for appending
      other sections of the source file to the same  destination
      file.
    * MKVToolNix GUI: multiplexer: the file selection dialogs now
      include the extension `.dtsma` for DTS files.
    * mkvmerge: MP4 reader: sped up parsing MP4 DASH files with a
      lot of segments (`trun` atoms) quite a bit.
    * The PCRE2 regular expression library is now used instead of
      `std::regex` for big performance improvements in all places
      where regular expressions are used for parsing big chunks of
      text, e.g. in the subtitle parsers.
    Bug fixes:
    * MKVToolNix GUI: preferences: under certain conditions
      changing the selected entry in the page tree on the left did
      not cause the page shown on the right to be updated.
    * mkvmerge: splitting text by a fixed string (e.g. `,`) is now
      done by using `std::string.find()` instead of using a
      regular-expression-based text splitting function, greatly
      improving its performance.
    * mkvmerge: MP4 reader: fixed handling of `tkhd` atoms of
      version 1.
    Build system changes:
    * The PCRE2 library (the 8-bit variant) is now required.
* Sun Aug 02 2020 aloisio@gmx.com
  - Update to version 49.0.0
    New features and enhancements:
    * mkvmerge: added support for copying the new track header
      elements `BlockAddIDName`, `BlockAddIDType`,
      `BlockAddIDValue` and `BlockAddIDExtraData` from Matroska
      files if they exist.
    * mkvinfo: added support for the new track header elements
      `BlockAdditionMapping`, `BlockAddIDName`, BlockAddIDType`,
      `BlockAddIDValue` and `BlockAddIDExtraData`.
    * MKVToolNix GUI: multiplexer: the list of recent directories
      can now be edited in the preferences → "Multiplexer" →
      "Destination file name".
    * MKVToolNix GUI: preferences: the values in the various
    "predefined values" lists can now be re-ordered freely by
      dragging & dropping.
    Bug fixes:
    * mkvmerge: Matroska reader: when reading tracks (e.g. a
      subtitle track) from Matroska files with their `default
      track` flag set to `yes`, and when overwriting those via the
      command line to `no`, `mkvmerge` would not promote
      additional tracks of the same type from other files (e.g.
      another subtitle track from an SRT file).
    * mkvmerge: SRT reader: empty lines inside entries were
      doubled.
    * mkvmerge: subtitles: when calculating the rounded duration
      of each entry the error from rounding the corresponding
      timestamp will be taken into account.
    * mkvextract: SSA/ASS extraction: mkvextract is no longer
      inserting empty lines before the `Dialogue:` lines.
    * mkvextract: USF subtitles: start & end timestamps were too
      high by a factor of 1.000.000.
    * MKVToolNix: info tool: when saving to a text file the
      checkbox "Save as default for saving output to text files"
      did nothing.
    * MKVToolNix: info tool: when saving to a text file in "all
      elements in a tree-like structure" mode, the GUI always
      stopped at the first cluster regardless of the setting of
      the "verbosity" option.
    * MKVToolNix GUI: preferences: when tooltips were disabled the
      dialogs for adding new entries to the various "predefined
      values" lists were missing their texts.
    * configure: fixed detection of QtDBus. Fixes #2886.
    Build system changes:
    * libMatroska v1.6.1 is now required. The bundled version has
      been updated to that version.
* Sun Jun 28 2020 Luigi Baldoni <aloisio@gmx.com>
  - Update to version 48.0.0
    New features and enhancements:
    * mkvmerge: AC-3: file identification will report AC-3 tracks
      encoded in Dolby Surround EX as codec "AC-3 Dolby Surround
      EX".
    * MKVToolNix GUI: multiplexer: on new installations the GUI
      will now recognize all known ISO 639-2 language codes in file
      names by default instead of only the top 100 of languages by
      native speakers.
    * MKVToolNix GUI: multiplexer: on new installations the list
      of "often used languages" will by default only contain
      certain agnostic ones ("multiple languages", "no linguistic
      content", "reserved for local use", "uncoded languages"),
      "English" and the default user interface language. The "list
      of spoken languages by native speaks" isn't used anymore.
    * MKVToolNix GUI: header editor: added an option to remove all
      attachments to the tree context menu.
    * MKVToolNix GUI: while the GUI is running it will remember
      the last page that was selected when the preferences dialog
      is closed. Upon re-opening the preferences that page will be
      selected by default.
    Bug fixes:
    * mkvmerge: fixed a segmentation fault when exiting
      prematurely due to write errors such as the destination
      having run out of space.
    * mkvmerge: DTS: fixed wrong channel count for DTS tracks with
      XCh extensions.
    * mkvmerge: MPEG TS reader: fixed detecting h.264/AVC and
      h.265/HEVC tracks that consist of only a single frame.
    * mkvmerge: MPEG TS reader: fixed handling of unbounded PES
      sizes for tracks that consist of only a single PES packet.
    * mkvmerge: MPEG TS reader: PGS subtitle tracks are now exempt
      from the "detect bogus subtitle timestamps" heuristic which
      could lead to some PGS subtitles not being timestamped
      correctly. Symptoms were that they were shown at the wrong
      time or that they were shown indefinitely.
    * mkvmerge: MPEG TS reader: when reading MPLS playlists the
      start timestamps of a play items were handled wrong: all the
      timestamps of packets read were compared to that start
      timestamp, dropping those packets whose timestamps were
      smaller than the play item's start timestamp. The correct
      behavior is to accept all packets as soon as the first one
      with a timestamp equal to or larger than the play item's
      start timestamp is encountered. This could result in PGS
      subtitle entries located right at the start of the play item
      being garbled/lost as they consist of multiple PES packets
      for which some timestamps are often slightly smaller.
    * mkvmerge: MPEG TS reader: when reading MPLS playlists
      mkvmerge will no longer read the whole M2TS files they
      reference, processing only the packets lying inside the
      timestamp range given by the playlists's play item's start &
      end timestamps. Instead mkvmerge will use the index
      information present in corresponding clip information (CLPI)
      files in order to seek to the nearest file position of the
      play item's start timestamp. Additionally mkvmerge will
      simply stop processing a file once the end timestamp is
      seen. This change greatly speeds up processing files from
      which only small portions must be read.
    * mkvmerge: WavPack: fixed support for files created by v5 of
      the program. Checksums, DSD audio data and non-standard
      sampling rates are handled correctly.
    * MKVToolNix GUI: multiplexer: fixed the cursor being
      positioned wrong after entering or pasting characters that
      aren't allowed in file names into the "destination file"
      control.
    Build system changes:
    * libEBML v1.4.0 and libMatroska v1.6.0 are now required.
    Other changes:
    * The source code repository's main development branch was
      renamed to `main`.
* Tue Jun 02 2020 Michel Normand <normand@linux.vnet.ibm.com>
  - Add _constraints file to avoid build error for ppc64/ppc64le
* Sat May 30 2020 Luigi Baldoni <aloisio@gmx.com>
  - Update to version 47.0.0
    New features and enhancements:
    * mkvmerge: chapters: mkvmerge can now read chapters from DVDs
      if the user specifies the path to a DVD folder structure via
      the `--chapters …` parameter. By default chapters from the
      first title will be imported. This can be changed by append
      `:<title number>` to the file/directory name in the
      `--chapters …` argument, e.g. `--chapters
      /srv/dvds/BigBuckBunny/VIDEO_TS:3`. This feature requires
      mkvmerge to have been built with the `libdvdread` library.
    * mkvmerge: added `--engage append_and_split_flac` that
      enables mkvmerge to append and split FLAC tracks, restoring
      pre-v45 behavior. The resulting tracks will be broken: the
      official FLAC tools will not be able to decode them and
      seeking will not work as expected.
    * MKVToolNix GUI: multiplexer: added support for mkvmerge's
      new support for reading chapters from DVDs if both have been
      built with the `libdvdread` library.
    * MKVToolNix GUI: multiplexer: when deriving languages from
      file names the GUI will now look for simplified language
      names instead of the full ones (e.g. instead of looking for
      "Greek, Modern (1453-)" it would simply look for "Greek").
    * MKVToolNix GUI: multiplexer: the options in the "additional
      command-line options" dialog are now sorted alphabetically.
      Additionally the `--append-mode` option has been added as
      one of the only missing global options.
    * MKVToolNix GUI: chapter editor: the chapter editor can now
      read chapters from DVDs if MKVToolNix has been built with
      the `libdvdread` library.
    * MKVToolNix GUI: header editor: added an option in the
      preferences for displaying all date & time values in UTC
      instead of the local time zone.
    Bug fixes:
    * all: fixed a crash when using the `MTX_LOGGER=file` syntax
      for logging debug messages without specifying a file name to
      log to. It will now log to a file called
      `mkvtoolnix-debug.log` in the system's default temporary
      directory, as initially intended.
    Build system changes:
    * The `libdvdread` library will be used if found via
      `pkg-config`. If it is found, support for reading chapters
      from DVDs will be enabled in `mkvmerge` and the MKVToolNix
      GUI.
    * Boost's Date/Time, Lexical Cast, Range, Range Adaptors,
      Tri-Bool, Variant libraries are not used anymore.
    * MKVToolNix now requires a C++ compiler & standard library
      that support the following features of the C++17 standard:
      "`std::variant`", "`std::gcd`". For the GNU Compiler
      Collection (gcc) this means v7 or newer; for clang it means
      v4 or newer — the same versions required by earlier
      MKVToolNix versions.
    * MKVToolNix now requires version 6.1.0 of fmtlib or later for
      the `fmt::to_string` function and bugfixes to the formatting
      of floating point numbers. If a system-wide version is
      installed that's older, the bundled copy will be used.
* Fri May 01 2020 Luigi Baldoni <aloisio@gmx.com>
  - Update to version 46.0.0
    New features and enhancements:
    * mkvmerge: when splitting, the placeholder `%c` can be used
      in the destination file name. It'll be replaced by the name
      of the first chapter in the file. Implements #2791.
    * mkvmerge: when reading MPLS playlists mkvmerge will include
      a tag named `SOURCE_ID` in the track's statistics tags that
      conveys the fact that the source was a Blu-ray and what the
      track's ID was in the source container. When reading Matroska
      file existing `SOURCE_ID` tags will be kept. The format used
      is the same format MakeMKV uses. Implements #2774.
    * mkvmerge: for audio-only files mkvmerge will now write a cue
      entry every 500ms instead of every 2s.
    * MKVToolNix GUI: job actions: split up the option "execute
      when the job finishes successfully or with warnings" into two
      separate options: "…when finishes successfully" and "…when
      exits with warnings". Implements #2798.
    Bug fixes:
    * mkvmerge: Matroska reader: when regenerating UIDs for
      chapters mkvmerge will now fix referencing tag chapter UID
      targets to have the same values. Fixes #2804.
    * mkvmerge: MP4 reader: fixed a crash that could potentially
      happen while trying to identify H.265/HEVC tracks.
    * mkvmerge: MP4 reader: when reading H.265/HEVC tracks without
      a frame offset table (`ctts` atom) present, mkvmerge did not
      parse the `hevcC` structure correctly in certain cases,
      causing no video frames to be output at all or the output not
      being playable. This fixes #2782, a bug introduced in v45.
    * mkvmerge: MPLS handling/MPEG TS reader: timestamp
      restrictions as given in an MPLS file were only honored for
      the first play item, not for subsequent play items. For those
      play items the whole referenced file was always copied. Part
      of the fix of #2789.
    * mkvmerge: MPLS handling/MPEG TS reader: under certain
      circumstances mkvmerge copied one frame too many before
      switching to the next play item. Part of the fix of #2789.
    * mkvmerge: for audio-only files cues will only be created for
      I frames (important for e.g. TrueHD where decoding can only
      start on a sync frame). Fixes #2790.
    * MKVToolNix GUI: fixed a crash that happened when closing the
      preferences after having closed at least one multiplexer tab.
      Fixes #2785.
* Sat Apr 04 2020 Luigi Baldoni <aloisio@gmx.com>
  - Update to version 45.0.0
    New features and enhancements:
    * mkvmerge: mkvmerge has never supported appending & splitting
      FLAC audio tracks. mkvmerge will now emit error messages
      when the user attempts either instead of continuing and
      creating invalid FLAC tracks.
    * MKVToolNix GUI: added an option in the preferences to turn
      on eliding text on tab headers. If enabled, tab names will be
      shortened so that all tab headers fit into the window's
      width. Implements #2768.
    * MKVToolNix GUI: added an option in the preferences to
      disable all tooltips.
    * MKVToolNix GUI: multiplexer: if the file identification
      fails due to a JSON parser error, the output generated by
      `mkvmerge` will be output to `STDERR` allowing insight into
      what's gone wrong.
    * MKVToolNix GUI: multiplexer: if an error occurs during file
      identification, the name of the processed file will be
      mentioned in the error message.
    * MKVToolNix GUI: multiplexer: if an error occurs during
      identification of multiple files, the GUI will ask the user
      whether to continue or abort the identification process.
      Implements #2778.
    * MKVToolNix GUI: job queue: added an option in the
      preferences for removing completed jobs when exiting the
      program depending on their status. Implements #2769.
    Bug fixes:
    * mkvmerge: H.265/HEVC packetizer: fixed changing the NALU
      size length, it was using the wrong offset into the `hevcC`
      structure.
    * mkvmerge: MP4 reader: fixed calculating the duration of
      video tracks that only contain a single frame. Fixes #2747.
    * mkvmerge: MP4 reader: if there's no frame offset table
      (`ctts` atom) present for H.265/HEVC video tracks, mkvmerge
      will determine the timestamp order itself instead of relying
      on the timestamps in the MP4 being in the presentation order
      required by Matroska. Fixes #2777.
    * MKVToolNix GUI: multiplexer: when using the title as part of
      the destination file name (both automatically as well as
      using the "copy title to destination file name" function) all
      characters that aren't valid in a file name are replaced by
      hyphens.
    * MKVToolNix GUI: multiplexer: the "copy title to destination
      file name" function was broken when the "make file name
      unique" option in the preferences was disabled. In that case
      the file base name was removed regardless of what the title
      was set to at the time.
    * MKVToolNix GUI: multiplexer: when adding Blu-ray playlists
      the GUI used to only look for the English version of the disc
      library information (title & cover images). Now the GUI will
      present all disc library entries in the "select playlist to
      add" dialog & let the user chose which one to use (if any).
      Fixes #2765.
    * MKVToolNix GUI: multiplexer, info tool: fixed the "warn
      before overwriting" check wrt. jobs creating the same file.
      Fixes #2758.
* Mon Mar 09 2020 aloisio@gmx.com
  - Update to version 44.0.0
    New features and enhancements:
    * MKVToolNix GUI: header editor: the attachments can now be
      reordered via drag & drop. Implements #2753.
    Bug fixes:
    * mkvmerge: Matroska reader: when encountering certain errors
      in the track headers such as the codec ID not being present
      mkvmerge will simply skip those tracks instead of exiting
      with an error. Fixes #2737.
    * MKVToolNix GUI: multiplexer: the "ask before overwriting"
      functionality did not look for the correct file names when
      splitting was active. Fixes #2741.
* Mon Jan 27 2020 Luigi Baldoni <aloisio@gmx.com>
  - Update to version 43.0.0
    New features and enhancements:
    * MKVToolNix GUI: using one of the command line options
      `--info`, `--edit-headers` or `--edit-chapters` will make
      the GUI select the corresponding tool on startup even if no
      further file name is given. Implements #2723.
    * MKVToolNix GUI: multiplexer: added a setting in the
      preferences for changing the location of the MediaInfo
      executable for when the user accidentally selected the wrong
      one.
    Bug fixes:
    * mkvmerge: AVC/h.264 parser: the order of the NALUs before
      each key frame was sometimes wrong: mkvmerge wrote SPS & PPS
      after SEI NALUs. Now SPS & PPS NALUs are always written
    before the other NALUs. Patch by Torsten Hauska. Part of the
    implementation of #2709 and part of the fix of #2250.
    * mkvmerge: AVC/h.264 parser: when additional SPS or PPS NALUs
      (with IDs that haven't been seen so far) are found
      mid-stream, mkvmerge will prepend all following key frames
      with all current valid SPS & PPS NALUs (just like when SPS &
      PPS NALUs are overwritten mid-stream). Part of the fix of
      [#2250].
    * mkvmerge: MPEG TS reader: fixed detection of MPEG-1/2 video
      tracks consisting of very few frames. Fixes #2732.
    * mkvmerge: Ogg Opus reader: fixed the handling of Ogg Opus
      streams that contain a just one Ogg page (`mkvmerge` aborted
      with an exception). Fixes #2722.
    * MKVToolNix GUI: multiplexer: dragging & dropping XML files
      with chapters or tags to the GUI's window was broken in v42.
      Instead of adding the file names to the appropriate input
      boxes the GUI was running mkvmerge for file identification
      purposes which then failed. Fixes #2718.
* Thu Jan 02 2020 Luigi Baldoni <aloisio@gmx.com>
  - Update to version 42.0.0
    New features and enhancements:
    * mkvmerge: added an option for creating byte-identical files:
      `--deterministic <seed>`. Part of the implementation of
      [#2698].
    * mkvmerge: Matroska reader: mkvmerge will remove the `icpf`
      atom headers if they're present in frames read from Matroska
      files. Implements #2692.
    * mkvmerge: MP4 reader: ALAC tracks: the number of channels,
      sampling frequency and bit depth are now taken from the
      bitstream in order to fix bogus values on the container level.
      Implements #2714.
    * mkvpropedit: when changing track UIDs the referring elements
      in existing chapters & tags will be updated automatically,
      too. Part of the implementation of #2700.
    * mkvinfo: when the option `-p`/`--hex-positions` is used,
      element positions will be output regardless of the verbosity
      level. Part of the implementation of #2713.
    * mkvinfo: added the option `-P`/`--positions` for showing the
      position of each element in decimal regardless of the
      verbosity level used. Part of the implementation of #2713.
    * mkvinfo: added the option `-o`/`--continue` for continuing
      processing when the first cluster is encountered regardless
      of the verbosity level used. Part of the implementation of
      [#2713].
    * mkvinfo: added the option `-a`/`--all` for outputting all
      sub-elements (even cues & seek head entries) and not
      stopping at the first cluster regardless of the verbosity
      level used. Part of the implementation of #2713.
    * MKVToolNix GUI: multiplexer: added an option in the
      preferences for disabling adding cover images from Blu-ray
      discs. Implements #2693.
    * MKVToolNix GUI: multiplexer: added mkvmerge's new
      `--deterministic` option in the "additional command-line
      options" dialog. Part of the implementation of #2698.
    * MKVToolNix GUI: header editor:: when changing track UIDs the
      referring elements in existing chapters & tags will be
      updated automatically, too. Part of the implementation of
      [#2700].
    Bug fixes:
    * mkvmerge: HEVC ES parser: fixed a bug in the slice parser
      calculating the size of a field which in turn could have led
      to the slice's type being read wrong. Patch by Torsten
      Hauska. Fixes #2710.
    * mkvmerge: Matroska reader: fixed a segmentation fault when
      trying to read a file that uses header removal compression
      but no removed bytes are present in the track headers. Fixes
      [#2687].
    * mkvmerge: MPEG elementary stream parser: fixed an invalid
      memory access and use of uninitialized memory that could
      happen under certain circumstances. Fixes #2690.
    * mkvmerge: RealMedia reader: fixed a division by zero when
      all audio timestamps were zero. Fixes #2689.
    * mkvmerge: RealMedia reader: fixed an invalid memory access
      in the video frame assembly code triggered by invalid data
      in the file. Fixes #2691.
    Build system changes:
    * `std::optional` (C++17 feature) is now used instead of
      `boost::optional`.
    * `std::regex` is now used instead of `boost::regex`.
    Other changes:
    * New man page translations into French, Italian, Russian and
      Chinese Traditional have been added.
* Fri Dec 06 2019 Luigi Baldoni <aloisio@gmx.com>
  - Update to version 41.0.0
    New features and enhancements:
    * mkvmerge: Matroska reader: Vorbis tracks: stream comments
      (aka Vorbis comments) will be converted to Matroska
      attachments (for cover arts) and Matroska track tags (for
      other comments). Additionally the stream comments will be
      removed from Vorbis headers.
    * mkvmerge: MP4 reader: added support for reading Opus audio
      from MP4 files. Part of the implementation of #2673.
    * mkvmerge: MP4 reader: added support for reading VP9 video
      from MP4 files. Part of the implementation of #2673.
    * mkvmerge: Ogg reader: Vorbis, Opus & VP8 streams: stream
      comments (aka Vorbis comments) will be converted to Matroska
      attachments (for cover arts) and Matroska track tags (for
      other comments). Additionally the stream comments will be
      removed from Vorbis headers.
    * mkvmerge: WAV reader: added support for reading RF64 files.
    * MKVToolNix GUI: multiplexer: the list of predefined track
      names is now split up into three lists, one for each track
      type (audio, video & subtitles). Part of the implementation
      of #2654.
    * MKVToolNix GUI: multiplexer: when trying to add thumbnails
      for a Blu-ray the GUI will determine the thumbnail's pixel
      size from the thumbnail files if the XML file doesn't
      contain that information. This works for JPEG and PNG files.
      Implements #2674.
    * MKVToolNix GUI: general: line edits & combo boxes will now
      have a "clear text" button appear whenever they're not
      empty. Part of the implementation of #2654.
    * MKVToolNix GUI: update check: the dialog showing the latest
      news & version information states explicitly where the links
      take the user (the MKVToolNix `NEWS.md` file and YouTube
      respectively).
      Bug fixes:
    * mkvmerge: Matroska reader: mkvmerge did not copy the codec's
      private data when reading WavPack from Matroska files. Fixes
      [#2685].
    * mkvmerge: MPLS handling: re-added caching when using MPLS
      playlists as input files. Fixes #2666.
    * mkvmerge: MPEG TS reader: when reading an MPLS playlist, the
      calculation of the minimum timestamp to use for shifting all
      output timestamps to zero was wrong. It was wrongfully
      considering timestamps from packets it would not copy due to
      the MPLS's timestamp restrictions. This could lead to the
      first timestamps in the output file being quite large, e.g.
      more than a couple of minutes, causing sync problems when
      multiplexing together with other files. Fixes #2670.
    * MKVToolNix GUI: multiplexer: the automatic switch between
      aspect ratio & display width/height wasn't reflected in the
      configuration generated for `mkvmerge`. The user had to
      change between the two settings manually. Fixes #2660.
    * MKVToolNix GUI: multiplexer: the progress dialog shown when
      scanning a Blu-ray wasn't closed properly in certain
      situations. Fixes #2678.
    * MKVToolNix GUI: general: the configured font was not applied
      to a lot of controls (e.g. the file & track lists or the
      menu entries) on application startup. Instead the user had
      to open & close the preferences in order for the font to be
      applied to all controls. Fixes #2671.
* Sat Nov 09 2019 Luigi Baldoni <aloisio@gmx.com>
  - Update to version 40.0.0
    New features and enhancements:
    * mkvmerge: MP4 reader: added support for BMP covert art
      images.
    * MKVToolNix GUI: multiplexer: added an option to disable
      deriving the destination file name from the file title.
      Implements #2648.
    * MKVToolNix GUI: multiplexer: the content of the
      "stereoscopy" combo box has been simplified making the box's
      minimum width much smaller, allowing the user to resize the
      GUI's whole window to a much smaller width.
    * MKVToolNix GUI: multiplexer: whenever the user changes the
      "aspect ratio" or "display dimensions" controls, the
      corresponding radio button will be activated automatically.
      Implements #2651.
    * MKVToolNix GUI: Windows: added a setting in the preferences
      to disable the GUI's dark color mode even if Windows's app
      color mode is set to dark. Implements #2646.
    * MKVToolNix GUI: Windows: replaced the dark mode introduced
      in v39 with another dark mode that's less wasteful with
      space between widgets.
    Bug fixes:
    * mkvmerge: MP4 reader: mkvmerge was reading eight bytes too
      many for cover art images. This could cause file
      identification to fail when the cover art was located at the
      end of the MP4 file. Even if it succeeded, this meant too
      much data present in the attachment. Fixes #2650.
    * mkvmerge: MP4 reader: covert art images with unknown image
      types will be skipped instead of treated as JPEG images.
    Build system changes:
    * Qt 5.9.0 or newer is now required for building MKVToolNix
      GUI.
* Tue Nov 05 2019 Luigi Baldoni <aloisio@gmx.com>
  - Update to version 39.0.0
    New features and enhancements:
    * mkvmerge: Blu-ray: when reading an MPLS playlist mkvmerge
      will look up and use chapter names from the Blu-ray's
      "track/chapter names" meta data if it exists. Part of the
      implementation of 2486.
    * mkvmerge: MP4 reader: if present, cover art images (the
      `meta.udta.ilist.covr` atom) will be converted into
      attachments.
    * MKVToolNix GUI: multiplexer: when adding a playlist from a
      Blu-ray disc, the disc library meta data will be parsed, and
      the biggest thumbnail, if present, will be added as a new
      attachment with name `cover.jpg` (extension depends on
      thumbnail's extension). Implements #2644.
    * MKVToolNix GUI: multiplexer: when adding a playlist from a
      Blu-ray disc, the title from the disc library meta data will
      be set as the new file title if the disc library meta data
      contains one & no title has been set yet.
    * MKVToolNix GUI: multiplexer: the automatically generated
      destination file name will now be based on the file title if
      one is set at that point. This works in conjunction with the
      title being said from the Blu-ray disc library meta data.
    * MKVToolNix GUI: chapter editor: when reading chapters from
      an MPLS playlist the GUI will look up and use chapter names
      from the Blu-ray's "track/chapter names" meta data if it
      exists. Part of the implementation of 2486.
    * MKVToolNix GUI: Windows: added a dark mode that's enabled
      when Windows 10's dark mode is turned on.
    * translations: added a Bulgarian translation of the programs
      & the man pages by Симеон Цветков (see `AUTHORS`).
    Bug fixes:
    * mkvmerge: attachments without a file name won't be ignored
      anymore. Part of the fix of #2642.
    * MKVToolNix GUI: header editor: attachments with an empty
      name element will be shown as `<unnamed>` as originally
      intended. Part of the fix of #2642.
    * Linux AppImage: the AppImage will no longer change
      directories before running the desired executable allow the
      use of relative file names. Fixes #2632.
    Build system changes:
    * MKVToolNix now requires a C++ compiler that supports the
      following features of the C++17 standard: "`[[maybe_unused]]`
      attribute", "nested namespace definition",
      "structured bindings". For the GNU Compiler Collection (gcc)
      this means v7 or newer; for clang it means v4 or newer.
    * Boost 1.60.0 or newer is now required.
  - Use system nlohmann-json
  - Spec cleanup
* Sun Oct 06 2019 Luigi Baldoni <aloisio@gmx.com>
  - Update to version 38.0.0
    New features and enhancements:
    * mkvextract: chapters, tags & cue sheets will now be written
      to standard output if no file name is given, same as if `-`
      is given as the file name.
    * MKVToolNix GUI: job queue: added a new setting in the
      preferences' "job queue & job status" section that, when
      enabled, will cause the GUI to remove all output files
      created by jobs that are either aborted by the user or that
      end in an error. Implements #2614.
    Bug fixes:
    * all programs: macOS: fixed file access if the file name
      (including all path components) contains any Unicode
      character where NFC (Normalization Form Canonical Composed)
      and NFD (Normalization Form Canonical Decomposed) differ,
      e.g. German Umlauts. Fixes #2620.
    * mkvmerge: when splitting by chapters the user can now split
      by chapters coming from one of the appended files, too.
      Fixes #2625.
    * mkvmerge: AAC reader: fixed reading codec parameters
      (channels, sample rate) if a file starts with garbage that
      includes valid-but-bogus AAC headers. Fixes #2622.
    * MKVToolNix GUI: Hebrew was added to the list of often-used
      languages so that it can be selected by default again. Fixes
      [#2610].
    * MKVToolNix GUI: when updating the GUI's settings from
      v37.0.0 or older, the GUI checks if the list of often-used
      languages equals the built-in list from v36.0.0. If it does,
      it will be updated to the built-in list changed in v37.0.0.
      Fixes #2611.
    Build system changes:
    * Boost's Operators header library is now required.
* Mon Sep 02 2019 Ismail Dönmez <idonmez@suse.com>
  - Update to version 37.0.0
    New features and enchancements:
    * MKVToolNix GUI: the list of often used languages now contains those from
      Wikipedia's "List of languages by native speakers" by default. Also by
      default only those languages will be shown in the language drop-down boxes.
    * mkvmerge: mkvmerge now allows appending AV1, VP8, VP9, H.264/AVC and
      H.265/HEVC tracks whose pixel dimensions differ. Implements #2582.
    Bug fixes:
    * MKVToolNix GUI: multiplexer: fixed a bug in the "make destination file names
      unique" logic that caused an existing number-in-parenthesis at the end of
      the file base name to be removed in certain situations (e.g. when the first
      added file was named `m (3).mkv` and both `m (3) (1).mkv` and `m (3)
      (2).mkv` existed already, the GUI was suddenly use `m.mkv` instead of `m (3)
      (3).mkv`).
    * MKVToolNix GUI: on Windows the GUI is built with a slightly older version of
      the Qt library again (5.12.4). The Qt version used in release v36.0.0,
      v5.13.0, lead to crashes when doing certain things such as selecting
      multiple tracks in the multiplexer. Fixes #2605 and #26008.
    * source code: fixed building with Boost 1.71.0. Fixes #2599.
    * all: fixed the spelling of the H.264 & H.265 codec names.
    * mkvmerge: Blu-ray MPLS handling: mkvmerge will now find corresponding M2TS
      files even if the `clip_codec_identifier` playlist item field is not set to
      `M2TS` in the MPLS file. Fixes #2601.
    * mkvmerge: fixed handling of text files that use both DOS-style and
      Unix-style line endings resulting in problems such as text subtitle files
      not being parsed correctly. Fixes #2594.
* Wed Jun 26 2019 Luigi Baldoni <aloisio@gmx.com>
  - Update to version 35.0.0
    New features and enhancements:
    * mkvmerge: JSON identification: the "codec name" track
      property will be output as `codec_name`. The JSON schema has
      been bumped to v12 for this change.
    * MKVToolNix GUI: job queue: added a new type of action to
      execute after job completion: deleting source files for of
      multiplexer jobs. As this is a destructive operation, the
      action is disabled by default. Implements #869 and #2570.
    Bug fixes:
    * mkvmerge: the "codec name" track property wasn't copied from
      Matroska files. Fixes #2566.
    * MKVToolNix GUI: multiplexer: Windows: clearing the
      destination file name will reset the tab name to
      "\<No destination file\>" again. Fixes #2571.
    * MKVToolNix GUI: multiplexer: the file types were not
      re-translated if the UI language was changed. Fixes #2572.
* Fri Jun 07 2019 Ferdinand Thiessen <rpm@fthiessen.de>
  - Update to version 34.0.0:
    * mkvmerge: bugfix: all subtitle frames are now treated as key
      frames in order to fix wrong data in source files.
    bugfix: AV1: fixed frame timestamp calculation when reading
      bitstreams that lack timing information from IVF files.
    bugfix: Matroska reader: fixed an infinite loop that could
      happen with large video frames and applied timestamp files
      due to too much data being buffered at the wrong time.
* Tue Apr 16 2019 Ferdinand Thiessen <rpm@fthiessen.de>
  - Update to version 33.1.0:
    * Build with stack protection
  - Update to version 33.0.0:
    * mkvinfo: bugfix: when using the `--size` option, mkvinfo will
    now report the correctly if an element has an unknown size.
    * MKVToolNix GUI: bugfix: info tool: clusters with an unknown
    size will now be read and displayed correctly.
    bugfix: multiplexer: if a destination file names ends with a
    number in parenthesis (e.g. a year such as "(2017)"), that
    number will not be stripped anymore during the process of
    ensuring the destination file name is unique. Only those suffixes
    added automatically in prior attempts to make the file name
    unique will be removed.
  - Update to version 32.0.0:
    * mkvinfo: new feature: when sizes are output the size of the
    element's data portion is output in addition to the element's
    total size.
    * MKVToolNix GUI: new feature: info tool: the element's data
    portion is shown as an extra column.
    new feature: multiplexer: added column "Delay" to the track list
    containing the additional delay to apply during multiplexing.
    bugfix: the portable mode wasn't detected correctly when the
    current working directory the GUI was started from wasn't the
    directory the GUI's executable file was located it.
    bugfix: multiplexer: using button to change the current
    destination directory to one of the recently used ones did not
    update the file name according to the "make file name unique"
    setting.
    bugfix: multiplexer: the function "set destination file name from
    selected file's name" will now only change the destination file's
    name but not its path.
    * all: fixed handling of Unicode code points > U+FFFF.
  - Update to version 31.0.0:
    * all programs: New Feature: added a new option
    `--abort-on-warnings` that will cause the program to abort after
    it has emitted the first warning, similar to how it aborts after
    the first error.
    * mkvmerge, mkvextract: New Feature: when closing files that were
    opened for writing, cached data will not be flushed to storage
    automatically anymore. A new option was added to both programs
    (`--flush-on-close`) that re-enables flushing for people who are
    affected by data loss.
    The reason is that automatic flushing causes long delays in
    processing queues when the output by mkvmerge/mkvextract isn't
    the final product but just an intermediate result to be
    processed further.
    Bugfix: AVI reader: using DV type 1 AVIs will now result in an
    unsupported file type being reported instead of crashing mkvmerge
    Bugfix: HEVC: the height of interlaced streams will now be set
    correctly to the height of the full frame instead of the height of
    a single interlaced field.
    Bugfix: MP4 reader: edit lists consisting solely of elements that
    mkvmerge doesn't support (such as dwells) are simply ignored.
    Before no data was read for such tracks at all.
    Bugfix: text subtitles: entries with an explicit duration of 0ms
    will now be handled correctly: the 0ms duration will be stored
    in Matroska instead of the difference between the current and
    the following entry.
    * MKVToolNix GUI: New Feature: multiplexer: the dialog previewing
    different character sets for text subtitles will now keep the
    position of the displayed text when switching between character
    sets.
    Bugfix: multiplexer, chapter editor: fixed drag & drop handling
    with Qt 5.12.0 and newer.
    Bugfix: multiplexer: the GUI did not clean up temporary files
    created when running `mkvmerge`.
* Tue Mar 19 2019 plater <davejplater@gmail.com>
  - Fix Factory build by changing rubygem-rake build requirement to
    rubygem(rake) and adding libboost_system build dependency again,
    fixes boo#1129626
* Mon Jan 14 2019 Martin Pluskal <mpluskal@suse.com>
  - Drop libboost_system dependency as it is not needed
* Sat Jan 12 2019 Ferdinand Thiessen <rpm@fthiessen.de>
  - Update to version 30.1.0:
    * MKVToolNix GUI: bugfix: chapter editor: when opening a
    Matroska/WebM file that doesn't contain chapters and later
    saving chapters back to them, the editor was truncating the file
    down to a couple of KB in size.
  - Update to version 30.0.0:
    * MKVToolNix GUI: New Feature: multiplexer: a new button was
    added next to the "destination file" controls. Clicking it
    shows a menu with the ten most recently used output
    directories. Selecting one of them will change the destination
    file to the selected directory keeping the file name.
    New Feature: The ten most recently used values for the "relative
    output directory" and "fixed output directory" settings are now
    saved. The corresponding settings have been changed into combo
    boxes allowing quick access to those recent values.
    New Feature: The predefined split sizes and durations can now be
    customized in the preferences.
    New Feature: chapter editor: added an option in the "Chapter
    editor" menu for appending chapters from an existing file to the
    currently open editor tab.
    New Feature: Added an action in the context menu for copying the
    selected entry and all of its children to another open editor tab.
    Bugfix: removing a file added as an "additional part" will no
    longer cause a crash.
    * mkvextract: New Feature: WAV extractor: mkvextract will now
    write W64 files instead of WAV files if the file name extension
    is `.w64` or if the final file size is bigger than 4 GB, the
    file size limit for WAV files.
    * mkvmerge: Bugfix: all files opened for writing will now be
    flushed once before they're closed. This ensures the operating
    system actually writes all cached data to disk preventing data
    loss in certain situations such as power outages or buggy drivers
    in combination with suspending the computer.
    Bugfix: AAC: under certain conditions 8 channel audio files were
    taken for 7 channel ones.
  - Update to version 29.0.0:
    * MKVToolNix GUI: New Feature: added an option in the preferences
    for disabling automatic scaling for high DPI displays.
    New Feature: The GUI will now prevent the system from going to
    sleep while the job queue is running.
    * mkvmerge: Bugfix: chapter generation: the start timestamps of
    chapters generated in intervals was wrong for files whose
    smallest video timestamp was bigger than 0.
    Bugfix: MP4 reader: fixed handling of atoms whose size exceeds the
    parent atom's size.
    Bugfix: the chapter name template will now also be used when
    reading Ogg-style chapter files with empty chapter names.
    * mkvextract: Bugfix: AAC: mkvextract will now write the program
    config element (PCE) before the first AAC raw data packet if the
    PCE is present in the `AudioSpecificConfig` structure in the
    `Codec Private` Matroska element. The  PCE carries vital
    information about the number of channels and is required in
    certain cases.
    * mkvpropedit, MKVToolNix GUI's header editor: Bugfix: in
    situations when a one-byte space must be covered by a new EBML
    void element the following element must be moved up instead.
    If that moved element is a cluster, the corresponding cue
    entries will now be updated to reflect the cluster's new
    position.
* Tue Oct 30 2018 Ferdinand Thiessen <rpm@fthiessen.de>
  - Update to version 28.2.0
    * mkvmerge, mkvinfo, mkvextract, mkvpropedit, MKVToolNix GUI's info
    tool & chapter editor: fixed a case of memory being accessed after
    it had been freed earlier. This can be triggered by specially
    crafted Matroska files and lead to arbitrary code execution. The
    vulnerability was reported as Cisco TALOS 2018-0694 on 2018-10-25
    (CVE-2018-4022). Fixes boo#1113709.
  - Update to version 28.1.0
    * mkvmerge: bugfix: AV1 parser: fixed an error in the sequence
    header parser if neither the `reduced_still_picture_header` nor
    the `frame_id_numbers_present_flag` is set.
    bugfix: AV1 parser: when creating the `av1C` structure for the
    Codec Private element the sequence header OBU wasn't copied
    completely: its common data (type field & OBU size among others)
    was missing.
    bugfix: Matroska reader, AV1: mkvmerge will try to re-create the
    `av1C` data stored in Codec Private when reading AV1 from
    Matroska or WebM files created by mkvmerge v28.0.0.
    * MKVToolNix GUI: bugfix info tool: the tool will no longer stop
    scanning elements when an EBML Void element is found after the
    first Cluster element.
  - Update to version 28.0.0
    * mkvmerge: New feature: AV1 parser: updated the code for the
    finalized AV1 bitstream specification.
    New feature: AV1 packetizer: updated the code for the finalized
    AV1-in-Matroska & WebM mapping specification.
    New feature: AV1 support: the `--engage enable_av1` option has
    been removed again.
    New feature: MP4 reader: added support for AV1.
    New feature: DTS: implemented dialog normalization gain removal
    for extension substreams.
    New feature: VP9: mkvmerge will now create codec private data
    according to the VP9 codec mapping described in the WebM
    specifications.
    bugfix: JSON identification: fixed a bug when removing invalid
    UTF-8 data from strings before they're output as JSON.
    bugfix: MP4/QuickTime reader: fixed handling of PCM audio with
    FourCC `in24`.
    bugfix: MPEG transport stream reader, teletext subtitles: the
    decision whether or not to keep frames around in order to
    potentially merge them with the following frame is made sooner.
    That avoids problems if there are large gaps between teletext
    subtitle frames which could lead to frames being interleaved
    too late.
    * mkvmerge, mkvextract: New feature: simple text subtitles:
    added a workaround for simple text subtitle tracks that don't
    contain a duration.
    * mkvextract: New feature: added support for extracting AV1 to IVF.
    New feature: IVF extractor (AV1, VP8, VP9): precise values will
    be used for the frame rate numerator & denominator header fields
    for certain well-known values of the track's default duration.
    * MKVToolNix GUI: New feature: automatic scaling for high DPI
    displays is activated if the GUI is compiled with Qt ≥ 5.6.0.
    New feature: added a menu item ("Help" → "System information") for
    displaying information about the system MKVToolNix is running on
    in order to make debugging easier.
    New feature: multiplexer, header editor: the user can enter a list
    of predefined track names in the preferences. She can later select
    from them in "track name" combo box.
    * mkvextract: bugfix: IVF extractor (AV1, VP8, VP8): the frame rate
    header fields weren't clamped to 16 bits properly causing wrong
    frame rates to be written in certain situations.
    * mkvpropedit, MKVToolNix GUI's header editor: bugfix: fixed file
    corruption when a one-byte space must be covered with a new EBML
    void element but all surrounding elements have a "size length"
    field that's eight bytes long already.
* Thu Oct 18 2018 Ferdinand Thiessen <rpm@fthiessen.de>
  - Update to version 27.0.0:
    * mkvmerge: New feature: chapters: the timestamps of chapters
    read from containers or from chapter files can be adjusted
    (multiplication and addition) with the new
    `--chapter-sync` option or using the special track ID `-2`
    for the existing `--sync` option.
    Bugfix: AC-3: dialog normalization gain removal was corrupting
    E-AC-3 frames irreversibly by writing checksums in places where
    they didn't belong. Additionally only the first E-AC-3 frame in
    a Matroska was processed but not additional dependent frames in
    the same block.
    * MKVToolNix GUI: New feature: multiplexer: adjusted & added
    controls for mkvmerge's new feature of being able to adjust
    chapter timestamps.
    New feature: multiplexer: the GUI can now ask for confirmation
    when the user is about to create a file that won't contain
    audio tracks. It does this by default if at least one source
    file contains an audio track.
    Bugfix: fixed a leak of Windows font resources leading to a
    general slowdown and subsequent crash.
  - Update to version 26.0.0:
    * mkvmerge: New feature: chapter generation: if the name template
    given by `--generate-chapters-name-template` is empty, no names
    will be generated for the chapter atoms.
    New feature: chapters: chapter names generated from MPLS files
    will now use the name template if one is set via
    `--generate-chapters-name-template`.
    New feature: mkvmerge will no longer abort with an error message
    if no audio, video and subtitle tracks should be multiplexed.
    This allows copying of chapters from non-chapter source files.
    Bugfix: Matroska reader: fixed wrong timestamps when appending
    Matroska files where the second Matroska file's first timestamp
    is bigger than 0.
    Bugfix: MP4 reader: fixed division by zero errors during file
    identification if the timescale is 0 in the `MVHD` atom.
    Bugfix: Windows Television DVR files are now recognized as an
    unsupported file type. This prevents mis-detection as MPEG-2
    with an accompanying flood of error messages.
    * MKVToolNix GUI: New feature: the font size in the tool
    selector on the left will scale with the font size the
    user selects in the preferences.
    New feature: the GUI will no longer automatically resize the
    columns in tree and list views to match the content size.
    Instead it remembers and restores the widths set by the user.
    New feature: multiplexer: the chapter name template will now be
    set automatically to the name template in the preferences'
    "chapter editor" section. Additionally the option
    `--generate-chapters-name-template …` will be passed to
    mkvmerge in situations when mkvmerge will generate chapters.
    New feature: chapter editor: if the chapter name template is empty,
    chapters will be generated without names.
    New feature: chapter editor: added an option to remove all chapter
    names to the "additional modifications" dialog.
    Bugfix: info tool: under certain circumstances "cues" were shown at
    the wrong level (inside the previous master element instead of on
    lvel 1).
    Bugfix: job queue: fixed invalid memory handling and consequent
    crashes when using the "edit in corresponding tool & remove from
    job queue" option if one of the files in that job contained
    attached files.
* Wed Aug 08 2018 rpm@fthiessen.de
  - Update to 25.0.0:
    * mkvextract: New feature: VobSub extraction: empty SPU packets
      will now be dropped during extraction as other tools such as
      MP4Box cannot handle them correctly.
    Bugfix: fixed a crash when mkvextract with a non-Matroska file as
      the source file.
    * MKVToolNix GUI: New feature:: multiplexer: added options to only
      enable tracks of certain types by default.
    New feature: multiplexer: added an option to enable dialog
      normalization gain removal by default for all audio tracks for
      which the operation is supported.
    New feature: multiplexer: when deriving track languages from the
      file names is active and the file name contains the usual
      season/episode pattern, then only the part after the
      season/episode pattern will be used for detecting the language.
    New feature: multiplexer: the regular expression used for deriving
      track languages from the file names can now be customized in
      the preferences.
    New feature: multiplexer: the user can now customize the list of
      track languages the GUI recognizes in file names. This list
      defaults to a handful of common languages instead of the full
      list of supported languages.
    Bugfix: multiplexer: when scanning playlists, all playlists were
      offered for selection regardless of the value of the "minimum
      playlist duration" setting.
    Bugfix: multiplexer: deriving track languages from file names:
      the regular sub-expressions for ISO 639-1 codes could match
      on empty strings, too, causing matches in wrong places and hence
      no language being recognized in certain situations.
    Bugfix: header editor: fixed a crash when saving the file fails
      (e.g. because it isn't writable).
    Bugfix: header editor: the editor was wrongfully claiming that
      mandatory elements with default values cannot be removed in
      the "status" text.
    Bugfix: preferences: on macOS & Linux the setting "enable copying
      tracks by their type" wasn't restored on program start.
    Bugfix: the central area is now scrollable, allowing the GUI to be
      resized to almost arbitrary sizes.
    Bugfix: multiplexer: the "copy file title to destination file name"
      functionality will now replace everything in the destination file
      name up to the last period instead of only up to the first period.
    * mkvmerge: New feature: SRT/ASS/SSA text subtitles: for files for
      which no encoding has been specified, mkvmerge will try UTF-8
      first before falling back to the system's default encoding.
    New feature: SRT/ASS/SSA/WebVTT text subtitles: a warning is now
      emitted if invalid 8-bit characters are encountered outside valid
      multi-byte UTF-8 sequences.
    New Feature: Matroska & MPEG transport stream readers: the encoding
      of text subtitles read from Matroska files can now be changed
      with the '--sub-charset' parameter.
    New feature: MP4 reader: improved the detection of edit lists
      consisting of two identical entries, each spanning the file's
      duration as given in the movie header atom. The second entry is
      ignored in such cases.
    New feature: JSON identification: the "display unit" video track
      property is now reported as `display_unit`. The JSON schema has
      been bumped to v11 for this change.
    New feature: AVC/h.264: empty NALUs will now be removed.
    New feature: input: format detection uses file-extension to improve
      performance and to give preference when several formats match.
    New feature: AV1: added support for reading AV1 video from
      Open Bitstream Unit files.
    New feature: AV1: adjusted the code for the AV1 bitstream format
      changes made up to 2018-05-02 (git revision d14e878).
    New feature: MP4 reader: if a track has an edit list with two
      identical entries, each spanning the file's duration as given in
      the movie header atom, then the second entry will now be ignored.
      Improves the handling of files with bogus data.
    Bugfix: AVC/h.264 and HEVC: fixed file identification failing
      for certain elementary streams due to internal buffers not
      being cleared properly.
    Bugfix: MLP code: fixed various issues preventing MLP from being
      parsed correctly.
    Bugfix: TrueHD/MLP packetizer; dialog volume normalization removal
      isn't attempted if the track is an MLP track as the operation is
      only supported for TrueHD, not MLP.
    Bugfix: MPEG TS reader: when reading MPLS mkvmerge will now
      compare the MPLS's start and end timestamps against the transport
      stream's PTS instead of its DTS. Otherwise the first key frame of
      a video track might be dropped if it isn't the first in
      presentation order.
    Bugfix: JSON identification: mkvmerge will ensure that all strings
      passed to the JSON output modules are valid UTF-8 encoded strings
      by replacing invalid bytes with placeholder characters. This avoids
      the JSON library throwing an exception and mkvmerge
      aborting on such data.
    Bugfix: audio packetizers: mkvmerge will now keep discard
      padding values if they're present for packets read
      from Matroska files.
    Bugfix:  Ogg Opus reader: packet timestamps aren't calculated by
      summing up the duration of all packets starting with
      timestamp 0 anymore. Instead the algorithm is based on the Ogg page's
      granule position and which packet number is currently timestamped
      (special handling for the first and last packets in the stream).
    Bugfix: E-AC-3 parser: fixed determining the number of channels for
      streams that contain an AC-3 core with dependent E-AC-3 frames.
    Bugfix:  Matroska reader: fixed mkvmerge buffering the whole file if a
      video track is multiplexed that consists of only one or a few frames.
    Bugfix: the "display unit" video track property will now be kept if
      it is set in the source file.
    Bugfix:  MP3 packetizer: removed a memory leak growing linearly with the
      track's size.
    Bugfix: VobSub packetizer: whenever a VobSub packet doesn't contain a
      duration on the container level, mkvmerge will now set it from
      the duration in the SPU packets. Before it was accidentally setting
      the SPU-level duration to 0 instead.
    Bugfix:  track statistics tags: if writing the `Date` element is
      deactivated via `--no-date`, the `_STATISTICS_WRITING_DATE_UTC`
      isn't written either anymore.
    Bugfix: removed several small, constant-size memory leaks.
* Mon Apr 09 2018 rpm@fthiessen.de
  - Update to 22.0.0:
    * mkvmerge: New feature: AC-3, DTS, TrueHD: added an option for
      removing/minimizing the dialog normalization gain for all
      supported types of the mentioned codecs.
    New feature: AV1: added support for reading AV1 video from IVF,
      WebM and Matroska files.
    New feature: FLAC: mkvmerge can now ignore ID3 tags in FLAC
      files which would otherwise prevent mkvmerge from detecting the
      file type.
    Bugfix: MP4 reader: fixed reading the ESDS audio header atom if
      it is located inside a "wave" atom inside the "stsd" atom.
    Bugfix: MP4 reader: AAC audio tracks signalling eight channels
      in the track headers but only seven in the codec-specific
      configuration will be treated as having eight channels.
    Bugfix: MPEG TS reader: fixed wrong handling of the continuity
      counter for TS packets that signal that TS payload is present
      but where the adaptation field spans the whole TS packet.
    Bugfix: the 'document type version' and 'document type read version'
      header fields are now set depending on which elements are
      actually written, not on which features are active.
    Bugfix: the 'document type version' header field is now set
      to 4 correctly if any of the version 4 Matroska elements
      is written.
    * mkvinfo: New Feature: the size and positions of frames
      within "SimpleBlock" and "BlockGroup" elements are now shown
      the same way they're  shown for other elements.
    Bugfix: summary mode: the file positions reported for frames in
      `BlockGroup` elements did not take the bytes used for
      information such as timestamp, track number flags or lace sizes
      into account. They were therefore too low.
    * mkvpropedit, MKVToolNix GUI header editor: the
      'document type version' and 'document type read version' header
      fields are now updated if elements written by the changes require
      higher version numbers.
    Bugfix: mandatory elements can now be deleted if there's a default
      value for them in the specifications.
    * MKVToolNix GUI: multiplexer: added options for deriving the
      track languages from the file name by searching for
      ISO 639-1/639-2 language codes or language names enclosed in
      non-word, non-space characters.
    Bugfix: info tool: implemented reading all elements in the file
      after the first cluster. Only top-level elements are shown;
      child elements are only loaded on demand.
    Bugfix: info tool: added a context menu with the option to show a
      hex dump of the element with the bytes making up the EBML ID and
      the size portion highlighted in different colors.
      In-depth highlighting is done for the data in `SimpleBlock`
      and `Block` elements.
    Bugfix: chapter editor: added an option to remove all end
      timestamps to the "additional modifications" dialog.
  - Update to 21.0.0:
    * mkvinfo: the GUI portion has been removed. mkvinfo is now a pure
      command-line program again.
    * mkvmerge: New feature: track statistics tags: the `TagDefault`
      element will not be written anymore as it was always set to the
      default value `1` anyway.
    New feature: JSON files can now contain C++-style line comments
      outside of strings. Such comments, even though not part of the
      official JSON specifications, are now ignored when reading JSON
      files.
    Bugfix: Appending files with additional parts at the same time
      was broken if more than one additional part was appended.
    Bugfix: FLV reader: a single invalid AAC frame was written for
      AAC audio tracks with codec initialization data longer than five
      bytes.
    Bugfix: FLV reader: timestamps will be normalized down to 0.
    Bugfix: MP4 reader: if an AAC track doesn't contain an
      AAC-specific decoder configuration in the ESDS portion,
      then a default decoder configuration will be generated based on
      the track's header data instead of skipping the track.
    Bugfix: MP4 reader: fixed reading HEVC/h.265 video tracks if
      they're stored as Annex B byte streams inside MP4.
    Bugfix: Ogg Opus reader: mkvmerge will now emit a warning
      instead of aborting when it encounters an Ogg Opus page with
      no data in the packet.
    Bugfix: Matroska parser: fixed a segmentation fault that
      occurred whenever the first level 1 element after resyncing
      after an error in the file structure isn't a cluster.
    Bugfix: fixed a crash during file type detection for
      attachments if MKVToolNix is installed in a path with
      non-ASCII characters (e.g. German Umlauts).
    * MKVToolNix GUI: New Feature: chapter editor: opening a
      Matroska file without chapters in it will now open the file
      in an empty chapter editor instead of showing an error message.
    New Feature: an "info" tool has been added, replacing the
      functionality of mkvinfo's GUI. The functionality is not on
      par yet but will be for release v22.
    Bugfix: MKVToolNix GUI: Bugfix: multiplexer: the subtitle
      character set can now be set for appended subtitle files, too.
    Bugfix: MKVToolNix GUI: multiplexer: when appending, all tracks
      appended to disabled tracks will start out disabled, too.
    * mkvinfo: the `--hex-positions` parameter did nothing in summary mode.
    Bugfix: mkvinfo: Windows: line endings will be written as `\r\n`
      again instead of just `\n`.
    * mkvpropedit: Bugfix: adding track statistics tags: for tracks
      with content encoding (compression) mkvpropedit is now
      accounting the uncompressed number of bytes, not the encoded
      (compressed) number of bytes.
* Sun Jan 21 2018 rpm@fthiessen.de
  - Update to 20.0.0:
    * Feature removal: several deprecated features have been removed:
    mkvmerge: the deprecated options `--identify-verbose`,
      `--identify-for-gui`, `--identify-for-mmg` and
      `--identification-format verbose-text`
    all command line tools: support for the deprecated, old,
      proprietary format used for option files
    all command line tools: support for passing command line
      options via the deprecated environment variables
      `MKVTOOLNIX_OPTIONS`, `MKVEXTRACT_OPTIONS`, `MKVINFO_OPTIONS`,
      `MKVMERGE_OPTIONS` and `MKVPROPEDIT_OPTIONS`
    * mkvmerge: AVC/h.264 packetizer (framed): access unit delimiter
      NALUs will now be removed.
    bugfix: AVC/h.264 parser: when fixing the bitstream timing
      information mkvmerge will now use exact representations of
      the desired field duration if possible.
    bugfix: AVC/h.264 parser: mkvmerge no longer assumes that
      encountering sequence parameter set or picture parameter set
      NALUs signal the start of a new frame.
    bugfix: AVC/h.264 packetizer (framed): when mkvmerge is told
      to fix the bitstream timing information, it will now update
      all SPS NALUs, not just the ones in the AVCC.
    bugfix: MPEG TS reader: TS packet payloads will only be
      treated as PES packets if the payload actually starts with
      a PES start code. The prior behavior led to wrong timestamps
      and potentially broken frame data.
    bugfix: MPEG TS reader: mkvmerge will now drop incomplete PES
      packets as soon as an error is detected in the transport
      stream instead of passing the incomplete frame to the
      packetizer. An error is assumed either if the
      `transport_error_indicator` flag is set or if the value of
      the `continuity_counter` header field doesn't match the
      expected value.
    bugfix: Opus: when re-muxing Opus from Matroska mkvmerge will
      now write "block duration" elements for all block groups
      where a "discard padding" is set, too.
    bugfix: SRT reader: mkvmerge can now handle SRT files with
      timestamps without decimal places.
    bugfix: read buffer I/O class: the class could get out of sync
      regarding the file position of the underlying file I/O class
      causing wrong data to be returned on subsequent read
      operations. One result was that trying to identifying MPLS
      files that refer to very short M2TS files caused mkvmerge
      to segfault.
    bugfix: multiplexer core: if there's a gap in audio timestamps,
      a new block group/lace will be started for the first frame
      after each gap. Before the fix the frame after the gap was
      often stored in the previous block group causing the gap to
      be in the wrong place: at the end of that block group.
    * mkvextract: bugfix: AVC/h.264: if two consecutive IDR frames
      with the same `idr_pic_id` parameter and no access unit
      delimiters are found between them, mkvextract will insert an
      access unit delimiter in order to signal the start of a new
      access unit.
    * MKVToolNix GUI: bugfix: update check dialog: Markdown links will
      now be converted to clickable links.
* Mon Dec 25 2017 jengelh@inai.de
  - Update to new upstream release 19.0.0
    * mkvmerge: splitting by duration, by timestamps or by
      timestamp-based parts: mkvmerge will now consider the first
      key frame within 1ms of the requested value to be eligible
      for splitting.
    * mkvmerge: fixed reading text files encoded in UTF-16 order
      UTF-32 that have different forms of line endings (new lines,
      carriage returns or a mix of both).
    * MKVToolNix GUI: multiplexer: once a "subtitle/chapter
      character set" was set for a track it couldn't be changed
      back to the empty entry (= auto-detection) anymore.
* Tue Dec 12 2017 rpm@fthiessen.de
  -Update to 18.0.0:
    * mkvmerge: bugfix: AAC ADTS parser: fixed interpretation of the
      `channel_configuration` header element for ADTS files that do
      not contain a program configuration element: value 7 means
      7.1 channels.
    bugfix: Matroska identification: the `date_local` and
      `date_utc` attributes will only be output if the identified
      Matroska file actually contains the "date" header field.
    bugfix: WebVTT: mkvmerge did not recognize timestamp lines if
      the hours components were absent.
    enhancement: AVC & HEVC ES parsers: performance improvements
      by copying much less memory around.
    enhancement: tags: reintroduced a workaround for non-compliant
      files with tags that do not contain the mandatory `SimpleTag`
      element. This workaround was removed during code refactoring
      in release v15.0.0.
    * mkvpropedit: bugfix: GUI's header editor: the `date` header
      field won't be added automatically anymore whenever the
      segment info section is edited and the `date` element is
      either deleted or not present in the first place.
    * GUI: multiplexer: the "AAC is SBR/HE-AAC/AAC+" checkbox in
      the "audio properties" section will be disabled if the
      functionality is not implemented for the selected track's
      codec & container.
    enhancement: multiplexer: the "reduce to core" checkbox in
      the "audio properties" section will be disabled if the
      functionality is not implemented for the selected track's
      codec.
* Wed Nov 08 2017 rpm@fthiessen.de
  - Update to 17.0.0:
    * The word "timecode" has been changed to "timestamp" everywhere.
    This affects program output (including mkvinfo's), GUI controls,
    command line parameters (e.g. `mkvmerge --timestamp-scale …`) and
    file formats.
    All programs remain backwards compatible insofar as they still
    accept "timecode" in all those places.
    * mkvextract's command line interface has been changed to allow
    extraction of multiple items at the same time.
    * mkvmerge: New feature: AC-3: during identification regular AC-3
      and E-AC-3 tracks will now be identified differently for most
      container formats (exception: AVI, Real Media, Ogg/OGM).
      The codec will be reported as `AC-3` for regular AC-3 and as
      `E-AC-3` for E-AC-3 tracks instead of the combined `AC-3/E-AC-3`.
    bugfix: AAC ADTS parser: mkvmerge will now parse the
      `program_config_element` if it is located at the start of an AAC
      frame in order to determine the actual number of channels.
      This overrides invalid channel configurations in the ADTS headers.
    bugfix: fixed AC-3 being misdetected as encrypted MPEG program
      streams under certain conditions.
    bugfix: Dirac: under certain conditions (e.g. only muxing a single
      Dirac track without any other tracks) mkvmerge was always setting
      the pixel width & height to 123. The frame rate was wrong, too.
    bugfix: E-AC-3 in Matroska: if AC-3 cores and their corresponding
      E-AC-3 extension are located in two different Matroska blocks,
      then mkvmerge will now re-assemble them into a single block and
      only use the first block's timestamp.
    bugfix: SRT reader: fixed calculating the duration of entries
      starting with at a negative timestamp.
    bugfix: VC-1: under certain conditions (e.g. only muxing a single
      VC-1 track without any other tracks) mkvmerge was always setting
      the pixel width & height to 123. The frame rate was wrong, too.
    bugfix: command line options: an error message will be output if
      the single-value-form of the `--sync` option is used and it
      isn't a number (e.g. `--sync 0:asd`).
    * mkvpropedit, GUI's header editor: bugfix: both programs will now
      show proper error messages instead of crashing when certain
      kinds of data corruption is found when reading a file.
  - Update to 16.0.0:
    * mkvmerge: New feature MP4 reader: added support for Vorbis.
    bugfix: AAC reader: mkvmerge will now emit an error message for
      AAC files whose header fields imply a sampling frequency
      or number of channels of 0.
    bugfix: AVC/h.264 ES parser: fixed the calculation of reference
      information for P and B frames. This also fixes some P frames
      being marked as B frames and vice versa.
    bugfix: AVC/h.264 ES parser: only non-key frames that have the
      NALU header field `nal_ref_idc` set to 0 will be marked as
      "discardable" in `SimpleBlock` elements. Other half of the
      fix for #2047.
    bugfix: HEVC/h.265: the generation of the HEVCC structure
      stored in `CodecPrivate` was wrong in two places:
      1. the position of the number of sub-layers was swapped with
      reserved bits and 2. the VPS/SPS/PPS/SEI lists did not start
      with a reserved 1 bit.
    bugfix: output: the `doc type version` will be set at least
      to 2 if certain elements are written (`CodecState`,
      `CueCodecState`, `FlagInterlaced`).
    bugfix: output: the track header attributes `MinCache` and
      `MaxCache` will not be written anymore.
    bugfix: Matroska reader: the "key" and "discardable" flags of
      SimpleBlock elements will be kept as they are.
    bugfix: Matroska reader: if present in the file,
      the "white colour coordinate x" track header attribute was
      written to both "white colour coordinate x" and
      "white colour coordinate y" in the output file.
    bugfix: Opus output: mkvmerge will now put all frames with
      discard padding into their own block group.
    * MKVToolNix GUI: Bugfix: header editor: removed the check for
      external modification when saving the file.
    bugfix: job queue: fixed calculation of total progress when
      automatic removal of completed is enabled.
* Thu Aug 31 2017 rpm@fthiessen.de
  - Update to 15.0.0:
    * Requires libebml >= 1.3.5
    * Dropped disable-update-check.patch (upstream now provides
      configure option for disabling the update check).
    * mkvmerge, mkvpropedit, GUI's header and chapter editors: the
      programs will no longer add most missing Matroska elements that
      are mandatory but have a default value in the Matroska
      specification (e.g. the `TagLanguage` element with a value of
      `und` if it isn't present in its `SimpleTag` parent).
    * mkvmerge: the option `--colour-matrix` has been renamed to
      `--colour-matrix-coefficients` in order to match the
      specification more closely. The old option name will
      continue to be recognized as well.
    * all: bugfix: selecting the program's language (e.g. via the
      `--ui-language`command-line option or via the GUI's
      preferences) did not work on Linux & Unix if the `LANGUAGE`
      environment variable was set and didn't include the desired
      language.
    * MKVToolNix GUI: new feature: multiplex tool: added a new entry
      to the "source files" context menu labeled "Set destination
      file name from selected file's name". It will force the GUI
      to consider the selected file to be the reference for
      automatically setting the file name, no matter which file was
      originally added as the first file. It will also force setting
      the destination file name once if automatic destination file
      name generation is turned off in the preferences.
    new feature: multiplex tool: added an option in the preferences
      on "Multiplexer" → "Output" labeled "Only use the first source
      file that contains a video track". If enabled, only source
      files containing video tracks will be used for setting the
      destination file name. Other files that are added are ignore.
    new feature: header editor: added support for editing the video
      colour attributes.
    new feature: header editor: added support for the "video
      projection" track header attributes.
    new feature: job queue: selected jobs can now be move up and
      down by pressing the `Ctrl+Up` and `Ctrl+Down` keys.
      Additionally, push buttons to move them up & down are shown
      if the corresponding option is enabled in the preferences.
    bugfix: removed the keyboard shortcuts for switching between
      the different tools (e.g. `Ctrl+Alt+1` for the multiplexer).
      They overlapped with basic functionality on keyboards that
      use an `AltGr` key, e.g. German ones, where `AltGr+7` emits
      `{`. As `AltGr+key` is implemented as `Ctrl+Alt+key` under the
      hood, this means that `AltGr+7` is really `Ctrl+Alt+7` which
      the GUI now took to mean "switch to the job queue" instead of
      "insert `{`".
    bugfix: header editor: after saving the file the GUI wasn't
      updating its internal file modification timestamp. That lead
      to the GUI wrongfully claiming that the file had been
      modified externally when the user wanted to save the file
      once more, requiring a reload of the file losing all
      modifications made since saving the first time.
    * mkvmerge: new feature: added support for the
      "video projection" track header attributes.
    bugfix: DTS handling: some source files provide timestamps for
      audio tracks only once every `n` audio frames.
      In such situations mkvmerge was buffering too much data
      resulting in a single gap in the timestamps of one frame
      duration after frame number `n - 1` (the second audio
      timestamp read from the source file was used one output
      frame too early).
    * mkvinfo: new feature: added support for the
      "video projection" track header attributes.
    bugfix: fixed a null pointer dereference if an `EbmlBinary`
      element's data pointer is a null pointer.
    * mkvpropedit: new feature: added support for editing the
      video colour attributes.
    new feature: added support for the "video projection"
      track header attributes.
* Fri Aug 25 2017 rpm@fthiessen.de
  - Split boost-devel BuildRequires for Tumbleweed
  - Update to version 14.0.0
    * mkvmerge, mkvpropedit, MKVToolNix GUI (chapter editor):
    new feature: added support for chapters in WebM files that is
      spec-compliant by removing all tag elements not supported
      by the WebM spec.
    * translations: added a Romanian translation of the programs.
    * mkvmerge: bugfix: AVC/h.264 and HEVC/h.265 parser: fixed wrong
      frame order & timestamp calculation in certain situations when
      SPS (sequence parameter sets) or PPS (picture parameter sets)
      change mid-stream.
    bugfix: MPEG-1/-2 video: the "remove stuffing bytes" feature
      introduced in v5.8.0 was broken. In a lot of situations it
      did not detect the end of a slice correctly and removed 0 bytes
      that were actually part of the slice structure. Often there
      were no visual problems as decoders were able to ignore such
      errors, but in other cases there are visual artifacts upon
      decoding. As detecting the slice end properly requires parsing
      the whole slice structure, this feature has been removed again.
    bugfix: MPEG PS reader: fixed mkvmerge trying to handle an "end"
      code the same way as a "program stream map" code.
    bugfix: MPEG TS reader: mkvmerge won't emit warnings if the
      system's `iconv` library doesn't support the ISO 6937
      character set.
    bugfix: when appending fails the error message details (e.g.
      "the number of channels differs: 1 and 2") were often not output.
    new feature: AAC: implemented support for AAC with 960 samples per
      frame.
    new feature: identification: if the encoding/character set of a
      text subtitle track is known (e.g. because a byte order mark is
      present in the file), then it will be output during
      identification as the `encoding` property.
    new feature: WAV reader: added support for Wave64 files.
    * MKVToolNix GUI: bugfix: multiplex tool: implemented a workaround
      for a crash that could occur during drag & drop if at least one
      of the columns is hidden.
    bugifx: multiplex tool: appended tracks can no longer be enabled
      (selected for multiplexing) if the track they're going to be
      appended to is not enabled.
    bugifx: multiplex tool: if the GUI is set to ensure unique output
      file names, it will now verify that right before starting to
      multiplex/adding the job to the queue, too.
    bugifx: fixed the total progress reverting to 0% instead of
      staying at 100% when all jobs have finished. This was introduced
      by the attempt at fixing the computation of the value of total
      progress bar for multiple jobs running.
    new feature: multiplexer: if the encoding/character set of a
      subtitle track cannot be changed, the GUI will deactivate the
      "subtitle character set" drop-down box and ignore changes to it
      when multiple tracks are selected. Additionally, if the track's
      encoding is known and cannot be changed (e.g. due to a
      byte order mark in the file), that encoding will be selected in
      the drop-down box automatically. Both changes signal to the user
      that she doesn't have to take care of the encoding herself.
    new feature: chapter editor: added a function to the "additional
      modifications" dialog for calculating and setting the end
      timestamps.
    new feature: changed the shortcuts for switching between the
      various tools from `Alt+number` (e.g. `Alt+1` for the multiplexer
      tool) to `Ctrl+Alt+number` in order to avoid clashing with
      Windows' input method for arbitrary characters (pressing and
      holding `Alt` and typing the codepoint on the number pad).
    new feature: added a "Window" menu and entries with shortcuts for
      selecting the next (`Ctrl+F6`) respectively previous tab
      (`Ctrl+Shift+F6`) in the current tool.
* Thu Jul 13 2017 rpm@fthiessen.de
  - Update to version 13.0.0
    * mkvmerge: new feature: MPEG TS reader: information about
      multiple programs will be output as container properties during
      verbose/JSON identification.
    bugfix: MP4 reader: MPEG-1/2 video read from MP4 files was written
      with an invalid codec ID (e.g. `V_MPEG7`) in certain cases.
    bugfix: MPEG PS reader: made the file type detection less strict
      so that garbage at the start of the file doesn't prevent detection.
    bugfix: MPEG PS reader: (E-)AC-3 tracks were not detected if the very
      first packet for that track didn't contain a full (E-)AC-3 frame.
    bugfix: MPEG TS reader: fixed mkvmerge not detecting all tracks in
      MPEG transport streams containing multiple programs.
    bugfix: MPEG TS reader: fixed track content being broken for some
      tracks read from MPEG transport streams containing multiple programs.
    bugfix: JSON identification: the `stream_id` and `sub_stream_id`
      track properties were output as hexadecimal strings instead
      of unsigned integers. As the `ts_pid` track property was only
      used for MPEG transport streams, its value is now output as
      `stream_id` instead, and the `ts_pid` property has been removed.
      The JSON schema version has been bumped to 8 due to this change.
    bugfix: fixed a crash when appending video tracks where one track
      has a CodecPrivate member and the other one doesn't.
    bugfix: track statistics tags: the `NUMBER_OF_BYTES` tag
      is supposed to contain the number of bytes in a track before any
      of the content encoding schemes such as lossless compression
      is applied; however, mkvmerge was wrongfully using the number of
      bytes after the schemes had been applied.
    bugfix: CLPI & MPLS parsers: MPLS and CLPI files with version
      number `0300` as used on Ultra HD Blu-ray Discs are
      now accepted as well.
    * MKVToolNix GUI: new feature: multiplex tool: added a column
      "program" to the tracks list. Certain container types such
      as MPEG transport streams can contain multiple programs.
      The new column will contain the service name (think TV station
      names such as "arte HD") for such streams.
    bugfix: fixed computation of value of total progress bar for
      multiple jobs running.
    bugfix: multiplexer, adding new attachments: when the GUI checks
      if there's an attachment with the same name it will now
      disregard disabled attached files.
    new feature: multiplex tool: the dialog asking the user what to
      do with dropped files (add to current settings, add to new
      settings etc.) now remembers the previous decision and defaults
      to it the next time it's shown.
    new feature: tabs can now be closed by pressing the middle mouse
      button.
    * mkvpropedit: bugfix: fixed a crash when the selector used
      for `--tags` is invalid.
* Tue Jun 06 2017 olaf@aepfle.de
  - Adjust usage of gccN-c++ for Leap42 and SLE12
* Tue May 30 2017 rpm@fthiessen.de
  - Update to version 12.0.0
    * MKVToolNix GUI: new feature: the key combination
      Ctrl+Shift+Space will now toggle the selection of the current
      item in all tree views where multiple selections are allowed.
    new feature: chapter editor: added the extension `*.cue`
      to the "open chapter file" dialog.
    bugfix:preferences → job actions, type "play audio file":
      the GUI will no longer clear the audio file name input if the
      user aborts the audio file selection dialog.
    bugfix: multiplexer tool: the "show command line" dialog will no
      longer include the mkvmerge executable's location as the first
      argument for the two "MKVToolNix option files" escape modes.
    bugfix: header editor: empty track language elements are now
      treated the same as those set to invalid ISO 639-2 codes:
      as if they were set to `und` = "undetermined".
    new feature: watch jobs: the user can now have the GUI execute
      an action once as soon as the current job or the whole queue
      finishes. The actions are the same ones that can be configured
      to be run automatically after job or queue completion.
    new feature: implemented several built-in actions that can be
      executed either on special events or once via the "watch jobs"
      tool. These are: playing an audio file; hibernating, sleeping
      and shutting down the computer.
    new feature: multiplex tool: added a new option for what to do
      after starting to multiplex/adding to the job queue:
      "close current settings" will close the current multiplex
      settings without opening new ones.
    * mkvmerge: New feature: cue sheet parser: if the cue sheet
      contains a non-empty `TITLE` entry and if no other segment title
      has been set yet, then the segment title will be set to the
      cue sheet's `TITLE` value.
    new feature: added an option `--no-date` that prevents the "date"
      field from being written to the segment information headers.
    new feature: FLAC reader: added support for handling embedded
      pictures as attachments.
    new feature: MP4 reader: Added support for parsing the "COLR"
      atom and including its values as track headers.
    bugfix: HEVC/h.265 parser: fixed the superfluous copying of the
      'bitstream_restriction_flag' and its dependent flags in the
      VUI parameters of the sequence parameter sets if the timing
      information is present, too.
    bugfix: MPEG TS reader, AAC parser: the MPEG TS reader will now
      force the AAC parser to use the multiplex mode that the MPEG TS
      reader has detected. This prevents the AAC packetizer from
      mis-detecting it in its own attempt to identify the mode.
    bugfix: MPEG TS reader: valid MPEG transport streams that start
      with an h.264/h.265 start code were not recognized as a
      supported file type.
    bugfix: MPEG TS reader: fixed a potential read access from
      invalid memory addresses in the code parsing the program
      map table (PMT).
    bugfix: MPEG TS reader: if packets are encountered that belong
      to a PID not listed in the program map table (PMT), mkvmerge
      will attempt to determine their type and codec from the content.
      This supported content types are AAC (ADTS only) and AC-3.
    bugfix: MP4 reader: fixed finding and parsing the `colr` atom if
      there are more than one video extension atoms and the `colr` atom
      is not the first one.
    bugfix: MP4 reader: the `nclx` colour type of the `colr` atom is
      now recognized, too.
    bugfix: AAC parser: fixed mis-detection of certain data as valid
      ADTS AAC headers resulting in memory allocation failures.
    bugfix: AVC/h.264 parser: mkvmerge will now ignore bogus timing
      information in the sequence parameter sets.
    bugfix: AVC/h.264 & HEVC/h.265 parsers: all trailing zero bytes
      will now be removed from NALUs.
    bugfix: HEVC/h.265 parser: fixed copying the
      `bitstream_restriction_flag` and all dependent fields in the VUI
      parameters of the sequence parameter sets.
    bugfix: HEVC/h.265 parser: fixed the calculation of the number of
      parameter set arrays in the HEVCC data structure stored in
      CodecPrivate.
    * mkvpropedit: bugfix: header editor: added support for editing the
      "date" segment information field.
* Tue Mar 28 2017 rpm@fthiessen.de
  - Update to new release 10.0.0
    * mkvmerge: new feature AVC/h.264 and HEVC/h.265 parser: mkvmerge
      will now drop all frames before the first key frame as they
      cannot be decoded properly anyway.
    new feature HEVC/h.265 parser: added a workaround for invalid
      values for the "default display window" in the VUI parameters
      of sequence parameter sets.
    bugfix MP4 reader: fixed track offsets being wrong in certain
      situations regarding the presence or absence of edit lists
      ('elst' atoms) & composition timestamps ('ctts' atoms).
    bugfix MP4 reader: offsets in "ctts" are now always treated
      as signed integers, even with version 0 atoms.
    bugfix Matroska reader: fixed handling BlockGroups and
      SimpleBlocks with negative timestamps.
    bugfix MP3 packetizer: the MP3 packetizer will no longer drop
      timestamps from source containers if they go backwards.
      This keeps A/V in sync for files where the source was in sync
      even though their timestamps aren't monotonic increasing.
    bugfix AVC/h.264 parser: mkvmerge will now drop timestamps
      from the source container if no frame is emitted for that
      timestamp.
    bugfix HEVC/h.265 parser: mkvmerge will now drop timestamps
      from the source container if no frame is emitted for that
      timestamp.
    * mkvinfo: the timestamps of SimpleBlocks with negative
    timestamps are now shown correctly.
    * mkvextract: SSA/ASS: fixed extraction when the "Format"
    line in the "[Events]" section contains less fields than the
    default for SSA/ASS would indicate.
* Mon Feb 20 2017 rpm@fthiessen.de
  - Update to new release 9.9.0
    * mkvmerge: AC-3 handling: some source files provide timestamps
      for audio tracks only once every n audio frames. In such
      situations mkvmerge was buffering too much data resulting in
      a single gap in the timestamps of one frame duration after frame
      number n - 1 (the second audio timestamp read from the source
      file was used one output frame too early).
    bugfix MP4 reader: mkvmerge was only reading a small part of MP4
      DASH files where the first "moov" "mdat" atoms occur before the
      first "moof" atom.
    bugfix MP4 reader: edit list ("edts" atoms) that are part of the
      "moof" atoms used in MP4 DASH files weren't parsed. Instead the
      edit lists from the main track headers inside the "moov" atom
      were used.
    bugfix MP4 reader: when an MP4 DASH file contained both normal
      chunk offset table in their regular "moov" atoms, a
      sample-to-chunk table ("stsc" atom) whose last entry had a
      "samples per chunk" count greater than 1 and DASH "trun" atoms,
      then mkvmerge was calculating wrong positions the frame content.
    bugfix MP4 reader: mkvmerge couldn't deal with the key frame index
      table having duplicate entries. The result was that only key
      frames up to and including the first duplicate entry were marked
      as key frames in the output file. All other frames weren't, even
      though some of them were referenced from the key frame table
      after the first duplicate entry.
    bufix MP4 reader: when an MP4 file contained more than one copy of
      the "moov" atom (the track headers etc.), mkvmerge was parsing
      them all adding tracks multiple times.
    bugfix MP4 reader: fixed an integer overflow during the timestamp
      calculation leading to files with wrong timestamps. Such files
      could not be played back properly by most players.
    bugfix MPEG TS reader: if the PMT lists a DVBSUB track, mkvmerge
      will now recognize it without having to find a packet for it
      within the probed range.
    bugfix splitting by parts (both the "timestamps" and the "frames"
      variants): fixed the calculation of track statistics tags. When
      calculating the duration the skipped portions weren't taken into
      account leading to a too-high duration. As a consequence the BPS
      tag (bits per second) was wrong, too.
    bugfix reading files with DVB/HDMV TextSV subtitle tracks with
      invalid CodecPrivate caused mkvmerge to abort with an error
      from boost::format about the format string not having enough
      arguments.
    bugfix: fixed misdetection of certain AC-3 files as MP3 files
      which led to an error message that
      "the demultiplexer could not be initialized".
    bugfix: fixed huge memory consumption when appending big Matroska
      files with sparse tracks (e.g. forced subtitle tracks).
      The Matroska reader will now queue at most 128 MB of data.
    bugfix MP4 reader: the timestamps of all multiplexed tracks will
      now be 0-based properly.
    bugfix MP4 reader: the DTS-to-PTS offsets given by the "ctts"
      atoms are now applied for all tracks containing a "ctts" atom,
      not just h.264 & h.265 tracks.
    * Some new features and enhancements
  - Now required for man pages:
    libxslt-tools, docbook-xsl-stylesheets  and po4a
* Fri Jan 27 2017 rpm@fthiessen.de
  - Update to new release 9.8.0
    * mkvmerge: MP4 reader: when an MP4 file contained fewer entries
    for timestamps than frames (which they never should), mkvmerge
    would use 0 as the timestamp for all the other frames. This
    resulted in effects such as the last frame of an output file
    having a timestamp of 0 and in split files having a much longer
    duration than they should have. Fixes #1847.
    bug fix: the MPEG transport stream reader was using an outdated
    format for the "CodecPrivate" element for HDMV TextST subtitles.
    This has been updated to the current format which only contains
    the "dialog style element". Existing Matroska files using this
    outdated scheme can be fixed by running them through mkvmerge.
    bug fix: files smaller than 4 bytes were wrongly identified as
    MPEG transport streams.
    bug fix: if a codec delay is set for a track in the input file,
    it is kept. Fixes #1849. bug fix: fixed that the error message
    "not enough space on disk" was shown twice on some operating systems.
    teletext subtitle bug fix: fixed the handling of DVB teletext subtitles
    signaled with data unit ID 0x02 and that contain pages from multiple magazines.
    bug fix: when using --track-order without specifying all tracks,
    the track numbers could end up in a way the user did not expect.
    Now mkvmerge will always assign track numbers for those tracks
    that are listed in --track-order first. The other tracks are
    assigned numbers afterwards. Fixes the second part of #1832.
    bug fix: when reading Matroska files the movie title was always
    taken from the first Matroska source file, even if that file
    didn't have a title set. Fixes one part of #1832.
    MP4: fixed detection of MP3 audio when the object type ID in the
    ESDS signals MP2 and the track headers have invalid values for
    number of channels or sampling frequency. Fixes #1844.
    The command line option "--check-for-updates" has been removed.
    * GUI: the cache cleanup process that's run automatically when
    the GUI starts no longer blocks file identification until it
    is finished. Additionally the process will only be run once
    per release of MKVToolNix. Fixes #1860.
    certain failures during file identification that can be
    traced to broken installations won't be stored in the cache
    anymore. Without this fix the GUI would still use the cached
    failed identification result even though the underlying
    might have already been fixed.
    multiplexer: changing default values in the preferences (e.g. the
    default track language to set) did not affect files whose
    identification results had already been cached.
    multiplex tool bug fix: under certain circumstances the GUI was
    creating invalid JSON files when starting to multiplex resulting
    in an error message ("JSON option files must contain a JSON
    array consisting solely of JSON strings").
    re-worked the startup code not to use lock files when trying to
    open a socket for communicating with an already-running instance.
    This aims to prevent situations with stale lock files not being
    cleaned up and the GUI not starting anymore as a result.
    This might fix or prevent issues like #1805.
    * A lot of new features and enhancements, please refer to NEWS.md
  - Rebased disable-update-check.patch
  - spec file cleanup
  - Adjusted BuildRequires
    * Since 9.7.1 QT >= 5.3 is required
    * Since 9.7.1 a c++ compiler with some c++14 features is required
      e.g. gcc >= 4.9 or clang >= 3.4
* Wed Nov 30 2016 rpm@fthiessen.de
  - Update to new release 9.6.0
    * mkvmerge: bug fix: mkvmerge was entering endless loops under
      certain conditions when appending files.
      MPLS parser bug fix: fixed reading the "in" & "out"
      timestamps for "play items". This bug resulted in mkvmerge
      not reading the correct range from the referenced M2TS file
      under certain rare circumstances.
    * MKVToolNix GUI: job output tool bug fix: the button for
      acknowledging warnings & errors wasn't properly disabled when
      the user used outside methods of acknowledging them
    * mkvextract: VobSub bug fix: mkvextract will add a "langidx"
      line to the .idx file upon extraction.
    * mkvmerge & mkvextract: added support for HDMV TextST subtitles.
* Thu Oct 27 2016 rpm@fthiessen.de
  - Update to new release 9.5.0
    * mkvmerge: bug fix: The Ogg/OGM reader did not recognize Opus
      files with comment headers anymore.
      WAV reader bug fix: the track properties (channels, samplerate)
      for DTS and AC-3 in WAV will now be derived from the decoded
      bitstream headers instead of the WAV file header as the latter
      is often incorrect.
      WAV reader bug fix: fixed detection and merging of DTS in WAV
      that uses the 14-bytes-in-16-bytes packing method.
      MPEG transport stream reader bug fix: fixed mis-detection of
      certain h.264 files as MPEG transport streams.
      MPEG transport stream reader bug fix: fixed the handling of
      Blu-ray PCM audio with an odd number of channels by removing
      their alignment bytes.
      h.264 elementary stream handling bug fix: if mkvmerge ever
      encounters changing SPS or PPS NALUs (ones where their ID has
      been encountered before with different settings) in the h.264
      then it will prepend all following key frames with all
      currently active SPS and PPS NALUs. This enables playback from
      arbitrary key frames even if they require other SPS or PPS
      settings than the ones stored in the AVCC in CodecPrivate.
      VobSub handling bug fix: mkvmerge and mkvextract will now
      update the duration stored in the SPU bitsream with the
      duration from the container level if it differs at least 1ms.
    * mkvprpedit, MKVToolNix GUI: Added support for "field order"
      video track header element.
  - Use GPG signature for verification.
* Fri Sep 16 2016 rpm@fthiessen.de
  - Update to new release 9.4.2:
    * mkvmerge: bug fix: using very large --sync values with certain
      container formats was causing mkvmerge to abort muxing.
      bug fix: fixed an invalid memory access (use after free)
      during global destruction phase.
      bug fix: HEVC parser: fixed three invalid memory accesses.
      bug fix: MP4 reader: fixed an invalid memory access
      bug fix: AAC reader: fixed mkvmerge throwing an uncaught
      exception due to the sample rate being 0.
      bug fix: MP4 reader: an error message will be printed
      instead of an uncaught exception when an invalid atom chunk
      size is encountered during resync.
      bug fix: AVC & HEVC readers: the readers will now refuse to
      handle files where the detected pixel width or height is
      equal to or less than 0.
* Thu Sep 01 2016 rpm@fthiessen.de
  - Update to new upstream release 9.4.0:
    * MKVToolNix GUI: merge tool bug fix: the automatic adjustments
      to the output file name based on the track types selected for
      muxing and the mechanism for keeping output file names unique
      had been broken since release v9.3.0.
      chapter editor bug fix: overly long chapter names don't cause
      the GUI's window to become overly wide anymore.
    * mkvmerge: bug fix: mkvmerge does no longer emit a warning if no
      comment header packet is found when reading tracks from
      Ogg/OGM files.
      bug fix: VP8 in Ogg: fixed dropping the first frame and the
      timestamp calculation.
      bug fix: when appending files mkvmerge wasn't starting clusters
      on video key frame anymore for the first and all following
      appended files.
      DTS bug fix: if present mkvmerge will use an XLL extension's
      sample rate information as the sample rate to put into
      the track headers.
    * mkvpropedit: bug fix: mkvpropedit will no longer say that it's
      writing the changes if only attachment changes are specified
      and none of the specified attachments can be found.
    * Some enhancements, please refer to the changelog within the
      package.
* Fri Jul 15 2016 rpm@fthiessen.de
  - Update to new upstream release 9.3.1:
    * libebml >= 1.3.4 and libmatroska >= 1.4.5 are now required
    * A lot of bugfixes and new features, new mkv elements are
      supported, for a list of all changes, please refer to the
      changelog provided by the package.
* Tue May 31 2016 rpm@fthiessen.de
  - Update to new upstream release 9.2.0:
    * mkvmerge: bug fix: the "interval" chapter generation mode was
    always creating one chapter too many.
    bug fix: if a certain number of chapters had been generated with
    - -generate-chapters then mkvmerge wasn't replacing the void
    placerholder with the actual chapters.
    bug fix: fixed detection of (E-)AC-3 in MPEG TS files with
    unusual stream types (e.g. 0x87) but with (E-)AC-3 PMT
    descriptors.
    * mkvmerge, mkvextract: bug fix: fixed handling of Big Endian PCM
    with a bit depth other than 16, 32 or 64 bits/sample. Other
    formats were using the Little Endian codec ID, but their content
    was actually not byte-swapped to match it. Now those other bit
    depths are byte-swapped to Little Endian, too.
    * MKVToolNix GUI: merge tool bug fix: the track column "default
    track in output" wasn't taking into account if the track had its
    "default track" flag set to "no" in the source file. This would
    result in the column showing "yes" in certain situations even
    though mkvmerge would assign "no".
    * Some other improvements, some enhancements and other bugfixes,
    please refer to the changelog file provides with the package.
* Mon Apr 25 2016 rpm@fthiessen.de
  - Update to new upstream release 9.1.0:
    * mkvmerge: bug fix: AVC/h.264: fixed handling of interlaced frames
    with bottom field first.
    bug fix: mkvmerge will no longer abort reading a Matroska file
    with a structural error right before the first cluster.
    bug fix: the "text_subtitles" property of the JSON/verbose
    identification modes was always set to true for all subtitle
    tracks, even for those that aren't text subtitles (VobSub, PG).
    bug fix: the language code signaled in the MPEG TS PMT is taken
    into account when selecting the character encoding to use
    during decoding of the teletext subtitles, not just the
    "national character set" stored in the teletext page headers.
    * MKVToolNix GUI: bug fix: Fixed huge memory consumption in the
    JSON library by updating said JSON library.
    bug fix: In merge-tool: when adding playlists the GUI won't ask
    the user whether or not to scan if there's only a single
    playlist in that directory.
* Mon Mar 28 2016 rpm@fthiessen.de
  - Update to new upstream release 9.0.1:
    * mkvmerge: bug fix: regression in v9.0.0: the text subtitle
    packetizer was wrongfully assuming an encoding of UTF-8 if none
    was given instead of assuming the system's encoding. Fixes #1639.
    bug fix: if too many chapters had been generated with
    - -generate-chapters then mkvmerge created a bogus entry in the
    meta seek element and did not actually write the chapters to the
    file.
    bug fix: the DTS packetizer was setting the number of
    channels wrong sometimes when reducing to the DTS core. It was
    using the number of channels including the extensions instead of
    the channels of the core only.
* Mon Mar 28 2016 jengelh@inai.de
  - Update to new upstream release 9.0.0
    * mkvmerge: bug fix: fixed two more issues in the conversion of
    teletext subtitles to SRT subtitles.
    * mkvmerge: MP4/QuickTime reader: audio tracks with the FourCC
    "lpcm" are muxed as A_PCM/INT/LIT instead of A_QUICKTIME.
    * mkvmerge: bug fix: MP4/QuickTime reader: audio tracks can contain
    two instances of certain header fields in the STSD atom;
    mkvmerge now uses the v2 structure over v0, if present.
    * mkvextract: new feature: implemented the extraction of Big
    Endian PCM (codec ID A_PCM/INT/BIG) to WAV files. The content will
    be byte-swapped into Little Endian PCM in the process.
    * mkvmerge: enhancement: Big Endian PCM tracks will now be
    byte-swapped into Little Endian PCM, and the codec ID
    A_PCM/INT/LIT will be used, as many players do not support BE PCM
    inside MKVs.
* Mon Feb 22 2016 jengelh@inai.de
  - Update to new upstream release 8.9.0
    * gui: the default font size adjustment has been. Deactivated for
    the time being as it causes problems on high DPI Displays.
    * gui: ampersands in file names were shown as keyboard shortcuts
    in tab titles in various tools
    * gui: add ability (menu entry) for removing chapters from an
    existing Matroska file.
    * Polish translation provided
* Sun Jan 10 2016 rpm@fthiessen.de
  - Update to upstream release 8.8.0:
    * MKVToolNix GUI: bug fix: when using one of the
      "select all tracks (of type…)" actions the "properties" column
      didn’t show the selection.
      bug fix: the paths used in the variables and the executable are
      converted to the platforms native path separators.
    * mkvmerge: bug fix: fixed a mis-detection of an MPEG-2 video
      elementary stream as a TrueHD file which then caused a
      segmentation fault.
      bug fix: Matroska attachments with the same name, size and MIME
      type were not output during file identification.
      bug fix: fixed TrueHD detection both as raw streams as well as
      inside other contains if the stream does not start with a
      TrueHD sync frame.
    * Some GUI enhancements and new features, see full changelog:
      https://bunkus.org/videotools/mkvtoolnix/doc/ChangeLog
  - some spec file cleanup
* Thu Jan 07 2016 rpm@fthiessen.de
  - Update to upstream release 8.7.0:
    * all: reversion of a change: several ISO 639-2 codes of languages
      that are very old and not spoken anymore have been re-added
      due to feedback from users who did have a use for such codes.
      reversion of a change: all of the tools will write a byte-order
      mark (BOM) to text files encoded any of the UTF-* schemes again.
    * mkvmerge: bug fix: fixed the key frame detection for VP9 video
      tracks.
      bug fix: chapters were output as both "chapters" and
      "track_tags" in JSON identification mode.
      bug fix: AAC with low sampling frequencies was sometimes
      mis-detected with the wrong profile preventing appending it
      to other AAC tracks.
      bug fix: the progress calculation was sometimes outputting
      negative numbers when appending Matroska files whose timestamps
      don’t start at 0.
      bug fix: fixed the decisions whether or not to write the last
      frame of a track as a BlockGroup or a SimpleBlock and whether
      or not to write a block duration for that frame.
      bug fix: the Matroska reader now uses TrueHD-specific code
      when reading Matroska files. This can fix things like wrong
      frame type flags.
    * MKVToolNix GUI: bug fix: relative file names given on the
      command line were interpreted as being relative to the user’s
      home directory.
      bug fix: the "split mode" drop-down box got reset to
      "do not split" each time the preferences dialog was closed
      with the "OK" button
    * And a lot more enhancements and bugfixes, see full changelog:
      https://bunkus.org/videotools/mkvtoolnix/doc/ChangeLog
* Sat Dec 05 2015 rpm@fthiessen.de
  - Update to upstream release 8.6.1:
    * all: MKVToolNix now requires gcc 4.8.0 or later or clang 3.4 or
      later for compilation.
    change: none of the tools will write a byte-order mark (BOM) to
    text files encoded any of the UTF-* schemes anymore.
    * mkvmerge: bug fix: the VC-1 handlig code was duplicating the
      first sequence headers with each mux.
    enhancement: added JSON as an output format for file type
      identification.
    bug fix: fixed two issues causing mkvmerge to write invalid data
      when updating track headers.
    bug fix: the change to do a deeper file analysis if no seek head
      was found was causing huge increases in file type detection time
      as popular tools like x264 don’t write seek heads. The way
      elements at the end are searched has been changed to only scan
      the last 5 MB of the file instead of iterating over every
      level 1 element from the beginning of the file.
    * MKVToolNix GUI: bug fix: the options for linking to the
      next/previous segment UID were wrong.
    bug fix: the program changes its working directory to the
      user’s profile/home directory on startup allowing the removal of
      its installation folder even if a program started by the GUI
      (e.g. a web browser) is still running.
    bug fix: in certain situations the modified file would not contain
      a seek head before the first cluster anymore resulting in most
      players not finding elements such as attachments or the index
      located at the end of the file anymore.
    * Some other enhancements and bugfixes, see full changelog:
    https://bunkus.org/videotools/mkvtoolnix/doc/ChangeLog
  - Split package into commandline- (base) and gui-package,
    reduces overhead when installing on a headless system.
  - Replaced sed in prep with disable-update-check.patch to disable
    update check on startup (not needed with a package system).
  - Added mkvtoolnix-use-system-boost.patch from fedora to fix includes
    when building against boost from system.
* Thu Nov 05 2015 rpm@fthiessen.de
  - Update to upstream release 8.5.2:
    * mkvmerge: bug fix: fixed an endless loop when updating track
      headers caused by the fix for "Re-rendering track headers.
    bug fix: mkvmerge no longer creates a "next segment UID" field
      in the last file when splitting and segment linking is active.
    bug fix: fixed the values of the "previous/next segment UID"
      elements when splitting by parts with segment linking enabled.
    * MKVToolNix GUI: bug fix: the file/track columns aren't resized
      to fit their content when expanding/collapsing tree node
      anymore. Such expansion also happened when moving entries with
      the "move up/down" buttons.
* Thu Oct 22 2015 rpm@fthiessen.de
  - Update to upstream release 8.5.1 (security update):
    * build system: libEBML v1.3.3 and libMatroska v1.4.4 are now
    required due to important fixes for invalid memory accesses in
    those two releases. The copies included in the MKVToolNix source
    code have been updated to those releases as well.
    * MKVToolNix GUI: bug fix: the "save file" dialogs did not have
    the currently entered file name pre-selected anymore.
    bug fix: fixed a crash when loading corrupted
    job settings.
    bug fix (Linux): the function "open folder" was
    inserting a superfluous leading slash in the directory name.
    * mkvmerge: bug fix: updating the track headers wasn't working in
    some rare cases (corresponding error message "Re-rendering track
    headers: data_size != 0 not implemented yet").
  - Disable default setting for checking for updates (nonsense on a
    package system)
* Sun Oct 18 2015 rpm@fthiessen.de
  - Updated to version 8.5.0:
    * Modified .spec to also install translated manpages.
    * A lot of small bugfixes and enhancements.
    * MKVToolNix GUI: merge tool bug fix: the cropping parameters were
    not converted into parameters for mkvmerge at all.
    * mkvmerge: enhancement: the verbose identification for MP4 files
    will now derive basic audio parameters of MP3 and AC3 tracks
    from the bitstream instead of relying on the values in the
    track headers.
    bug fix: PCM tracks: if the number of samples per
    packet varies then no default duration will be written.
    * all: several ISO 639-2 codes of languages that are very old and
    not spoken anymore have been removed.
    new feature: added a Catalan translation of
    the man pages.
* Tue Sep 22 2015 rpm@fthiessen.de
  - Updated to version 8.4.0:
    * MMG has been removed.
    * Dropped wxWidgets dependencies (new gui uses QT).
    * A lot of bugfixes and enhancements of the gui and mkvmerge
    (see https://bunkus.org/videotools/mkvtoolnix/doc/ChangeLog).
    * mkvmerge: bug fix: calculating of delay for audio garbage data
    got fixed.
    * all: bug fix: parsing of strings containing negative values or
    timecodes was broken on 32-but architectures.
    * mkvmerge: bug fix: number of channels and the sample rate
    reported for DTS in MPEG streams was 0.
* Sun Aug 16 2015 jengelh@inai.de
  - Update to new upstream release 8.3.0
    * many small GUI bug fixes and improvements
    * mkvmerge: bug fix: fixed handling of MPEG transport streams
    where all PATs and PMTs have CRC errors.
    * mkvmerge: bug fix: the MPEG-1/2 video code was causing an
    illegal memory access under certain conditions.
    * mkvmerge: bug fix: fixed recognition of (E)AC3 audio tracks
    using a FourCC of "ec-3"
    * mkvmerge: bug fix: fixed codec identification for MP2 audio read
    from MPEG PS/TS.
    * mkvmerge: bug fix: fixed key frame designation for video tracks
    in MP4 DASH files.
* Wed Aug 05 2015 rpm@fthiessen.de
  - Update to version 8.2.0:
    * Fix mkvmerge codec identification for MP2 audio.
    A LOT more bugfixes especially in the GUI. See ChangeLog:
    https://bunkus.org/videotools/mkvtoolnix/doc/ChangeLog
* Fri May 29 2015 dimstar@opensuse.org
  - Update to version 7.9.0:
    * Fix build with boost 1.58.0.
    * build system: configure will now check for Qt by default.
    * A couple of important bugs have been fixed, e.g. a very old bug
    in handling MPEG-1/2 video preventing the detection of such
    tracks; if --sync was used at the same time as --default-duration
    then --sync was ignored; mkvinfo’s exit codes were wrong (this
    may trip up frontends using mkvinfo!); handling of E-AC3 in MPEG
    transport stream in certain situations.
* Sat Mar 28 2015 jengelh@inai.de
  - Update to new upstream release 7.8.0
    * mkvmerge: Fixed recognition of E-AC3 audio tracks in MPEG TS
    streams if they use the type ID 0xa1 (and the same for DTS tracks
    stored with type ID 0xa2).
    * mkvmerge: new feature: mkvmerge will now recognize TrueHD tracks
    inside MPEG transport streams that contain an AC3 core as
    consisting of two tracks.
    * mkvmerge: new feature: mkvmerge will now recognize TrueHD+AC3
    files as consisting of two tracks.
* Tue Feb 10 2015 opensuse@sukimashita.com
  - Update to new upstream release 7.6.0
    * all programs: bug fix: Since release 7.0.0 the wrong exit code
    was used when warnings were finished (0 instead of 1).
    * mkvmerge: bug fix: Appending chapters with the same chapter UID
    was dropping all sub-chapters from the one of the two merged
    chapters. Now the sub-chapters are merged recursively as well.
    * mkvmerge: bug fix: The wrong Codec ID was written when reading
    PCM tracks from Matroska files in Big Endian byte order.
    * all: new feature: added a Serbian (Latin) translation of the
    programs by Danko (see AUTHORS).
    * mkvmerge: bug fix: If splitting was active and AC3 tracks read
    from Matroska files were shorter than a split point then the
    following output file would contain an AC3 packet with the
    timecode of 00:00:00 somewhere in the middle.
    * mmg: bug fix: If a chapter track from a Matroska file is
    selected then the »language« drop-down box is disabled.
    * mmg: bug fix: When scanning for play lists the window presenting
    the results listed some properties in an unescaped way (e.g.
    »\s« instead of spaces).
    * mmg: bug fix: When adding MPLS files mmg was only offering to
    scan for more playlists if there were at least two additional
    MPLS files present. This has been fixed to one MPLS file (in
    addition to the one just added).
* Sun Feb 01 2015 jengelh@inai.de
  - Update to new upstream release 7.5.0
    * mkvmerge: Fixed reading MPEG transport streams in which
    all PATs and/or PMTs have CRC errors.
    * mkvmerge: Implemented support for MP4 DASH files.
    * mkvmerge: Implemented reading MPEG-H p2/HEVC video
    tracks from MP4 files.
    * mkvmerge: Implemented support for AAC in LOAS/LATM multiplex if
    read from MPEG transport streams or raw LOAS/LATM AAC files.
    * mkvmerge: Added support for recognizing H.265/HEVC video tracks
    in MPEG transport streams.
* Sat Dec 13 2014 coolo@suse.com
  - update to upstream release 7.4.0
    * Implements support for PCM in MPEG program (.vob – DVDs) and
    transport streams (.ts, .m2ts – Blu-rays, television broadcasts)
    as well as for teletext subtitles in MPEG tranport streams.
    Apart from that a lot of work has gone into the new GUI.
    * Bugfixes for muxing HEVC or teletext subtitles
