Version history / Release notes / Changelog
# 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.

HighCode : Must be a problem on your part.
Using Windows 10 64bit, MKVToolNix 56.0.0 and it works flawlessy (as previous versions), I can edit every field everywhere.
A very great and useful tool, hope they give it a GUI also for extracting tracks and it would be A-W-E-S-O-M-E.
But if you need to remux something, this is the best application you can find: 100% reliable and very easy to use.

For those using older versions- 9.7.0 through 10.0.0 occasionally create corrupt .mkv files (.H264 + .FLAC + .SRT sources in my case). The file will play, but at some point the video will freeze for a few seconds and then continue and the audio will become unsyncronized.
Versions before 9.7.0 do not have the issue. I don't know about versions higher than 10.0.0 as I haven't used those.
