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: 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: 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: multiplexer: changing the 'subtitle/chapter character set' drop-down was ignored when the selected track was a chapter track mkvextract: fixed slow track extraction speed on Windows due to lack of buffering mkvmerge: MPEG transport stream reader: fixed slow speed on Windows due to lack of buffering This means that the following new MIME types for fonts can be used: `font/ttf`, `font/otf`, `font/woff` and `font/woff2` mkvmerge, GUI's multiplexer: MIME types: added the `font` top-level media types from RFC 8081. In that case mkvmerge was reading the whole content more than once

mkvmerge: MP4 reader: fixed mkvmerge's interpretation of edit list entries with `segment_duration = 0` when there's more than one edit list entry. 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) 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

MKVToolNix GUI: the GUI will now save and restore the widths of columns in tree and list views mkvmerge will now consider the first key frame within 1ms of the requested value to be eligible for splitting Mkvmerge: splitting by duration, by timestamps or by timestamp-based parts: The MKVToolNix project's source code repository, bug tracker and wiki have been moved to The MKVToolNix project now contains a Code of Conduct]
