a nice new release is here, v9.8.0. Couple of enhancements, a couple
of bug fixes, especially for the new caching functionality introduced
in 9.7.0. I recommend upgrading.

Notes for package maintainers: important changes were made to the
build process. Please see the NEWS section below for details (both the
"important news" and the "build system changes" sections).

Here are the usual links:

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

The Windows and Mac OS binaries have been built already and are
available for download. The Linux binaries will be available later

Here's the NEWS since v9.7.1:

# Version 9.8.0 "Kuglblids" 2017-01-22

## Important notes

* build system: the included version of the "drake" build tool has been
  removed. Since Ruby 2.1 rake has supported parallel builds, too. The
  MKVToolNix build system has been adjusted to enable parallel builds by

## New features and enhancements

* mkvmerge: VobSub in Matroska: mkvmerge will now create and use a default
  index for VobSub tracks read from Matroska files that are missing their
  CodecPrivate element (which normally contains said index). Implements #1854.
* GUI: added checks for several common problems with the installation. These
  checks will be executed when the GUI starts, and any problems will be
  reported to the user.
* mkvmerge: added the ISO 639-2 language codes "qaa" and "qad" (both are
  titled "reserved for local use") as both are used often in France. See #1848
  for more information.
* mkvmerge: the JSON identification result now includes a track's codec delay
  if set (only for Matroska source files). The JSON schema version has been
  bumped to 6.
* mkvmerge: MPEG TS: added a workaround for files where the subtitle packets
  are multiplexed properly, but where their timestamps are way off from the
  audio and video timestamps. Implements #1841.
* mkvmerge: added support for Digital Video Broadcasting (DVB) subtitles
  (CodecID `S_DVBSUB`). They can be read from MPEG transport streams and from
  Matroska files. Implements #1843.

## Bug fixes

* 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.
* 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.
* GUI: certain failures during file identification that can be traced to
  broken installations (e.g. mkvmerge being too old) 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
* mkvmerge: fixed that the error message "not enough space on disk" was shown
  twice on some operating systems. Fixes #1850.
* mkvmerge, Matroska: if a codec delay is set for a track in the input file,
  it is kept. Fixes #1849.
* GUI: 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.
* mkvmerge, 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.

## Build system changes

* nlohman json-cpp: configure now looks for a system-wide installed version of
  the nlohmann json-cpp header-only library. If one is found, it is used;
  otherwise the included version will be used. Implements #1858.
* If MKVToolNix is built with rake v10.0.0 or newer, its "multitask" feature
  will be turned on allowing automatic parallel builds.
* CURL is no longer used by MKVToolNix and is therefore not required
  for building anymore.

## Other changes

* GUI: the update check now uses Qt's networking classes instead of CURL.
* The command line option "--check-for-updates" has been removed, even
  though the deprecation warning in release 9.7.0 stated that it would
  be removed in 2018.

Have fun :)
