Hey everyone.

I thought today would be a good day for a new release of MKVToolNix:
v22.0.0 is here. Celebrating the official announcement of AV1, this is
the first release that contains support for that format as well (still
some things to do, though). Other than that the info tool in the GUI
has been improved quite a bit.

Here are the usual links:

…to the source code: https://mkvtoolnix.download/source.html
…to the binaries: https://mkvtoolnix.download/downloads.html

The Windows and macOS binaries are available already. The Linux
binaries are still being built and will be available of the course of
the next couple of hours.

Here are the NEWS since the previous release:

# Version 22.0.0 "At The End Of The World" 2018-04-01

## New features and enhancements

* mkvmerge, MKVToolNix GUI multiplexer: AC-3, DTS, TrueHD: added an option for
  removing/minimizing the dialog normalization gain for all supported types of
  the mentioned codecs. Implements #1981.
* mkvmerge: AV1: added support for reading AV1 video from IVF, WebM and
  Matroska files.
* mkvmerge: FLAC: mkvmerge can now ignore ID3 tags in FLAC files which would
  otherwise prevent mkvmerge from detecting the file type. Implements #2243.
* mkvinfo: the size and positions of frames within "SimpleBlock" and
  "BlockGroup" elements are now shown the same way they're shown for other
  elements (by adding the `-v -v` and `-z` options).
* 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 (e.g. "…[ger]…"
  for German or "…+en+…" for English). Implements #1808.
* MKVToolNix GUI: 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. Implements the rest of #2104.
* MKVToolNix GUI: 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.
* MKVToolNix GUI: chapter editor: added an option to remove all end timestamps
  to the "additional modifications" dialog. Implements #2231.

## Bug fixes

* mkvmerge: MP4 reader: fixed reading the ESDS audio header atom if it is
  located inside a "wave" atom inside the "stsd" atom.
* mkvmerge: 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.
* mkvmerge: 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.
* mkvmerge: 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 (e.g. if a `SimpleBlock` is never written,
  then the 'read version' won't be set to 2 anymore). Part of the fix for
* mkvmerge: the 'document type version' header field is now set to 4 correctly
  if any of the version 4 Matroska elements is written. Part of the fix for
* mkvinfo: 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. Part of the fix for
* mkvpropedit, MKVToolNix GUI header editor: mandatory elements can now be
  deleted if there's a default value for them in the specifications. Fixes
* source code: fixed a compilation error on FreeBSD with clang++ 5.0. Fixes

## Build system changes

* A compilation database (in the form of a file `compile_commands.json`) can
  be built automatically if the variable `BUILD_COMPILATION_DATABASE` is set
  to `yes` (e.g. as `rake BUILD_COMPILATION_DATABASE=yes`).

Have fun :)
