What's new in this version:

Important notes:
- The MKVToolNix project now contains a Code of Conduct]
- The MKVToolNix project's source code repository, bug tracker and wiki have been moved to [GitLab]

New:
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
- MKVToolNix GUI: the GUI will now save and restore the widths of columns in tree and list views
- MKVToolNix GUI: header editor: when closing or reloading a modified file, the GUI will now focus the first element that's been modified before asking the user for confirmation regarding discarding unsaved changes

Bug fixes:
- 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)
- mkvmerge: MP4 reader: fixed mkvmerge's interpretation of edit list entries with `segment_duration == 0` when there's more than one edit list entry. In that case mkvmerge was reading the whole content more than once
- mkvmerge, GUI's multiplexer: MIME types: added the `font` top-level media types from RFC 8081. This means that the following new MIME types for fonts can be used: `font/ttf`, `font/otf`, `font/woff` and `font/woff2`
- mkvmerge: MPEG transport stream reader: fixed slow speed on Windows due to lack of buffering
- mkvextract: fixed slow track extraction speed on Windows due to lack of buffering
- MKVToolNix GUI: multiplexer: changing the "subtitle/chapter character set" drop-down was ignored when the selected track was a chapter track
- 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
- MKVToolNix GUI: header editor: fixed re-translating several displayed strings when the GUI language is changed if the language the GUI was started with was not English
- MKVToolNix GUI: header editor: whenever a file did not contain a "date" element in its segment information section, the GUI would erroneously ask the user to confirm discarding unsaved changes when closing or reloading the tab
- MKVToolNix GUI: job queue: jobs are now saved when their status changes in addition to when the program exits
