From the Official Site:
MKVToolnix is a set of tools to create, alter and inspect Matroska files under Linux, other Unices and Windows. They do for Matroska what the OGMtools do for the OGM format and then some.
With these tools one can get information about (mkvinfo) Matroska files, extract tracks/data from (mkvextract) Matroska files and create (mkvmerge) Matroska files from other media files. Matroska is a new multimedia file format aiming to become THE new container format for the future.

# Version 56.1.0 "My Friend" 2021-04-09
## 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. Fixes #3081.
## 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. Fixes #3083.
* 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.
