What's new in this version:

New features and enhancements:
- mkvmerge: chapter generation: if the name template given by `--generate-chapters-name-template` is empty, no names (`ChapterDisplay`master elements with `ChapterString`/`ChapterLanguage` children) will be generated for the chapter atoms
- mkvmerge: chapters: chapter names generated from MPLS files will now use the name template if one is set via `--generate-chapters-name-template`
- mkvmerge: mkvmerge will no longer abort with an error message if no audio, video and subtitle tracks should be multiplexed. This allows copying of chapters from non-chapter source files (e.g. Matroska or MP4 files)
- MKVToolNix GUI: the font size in the tool selector on the left will scale with the font size the user selects in the preferences
- MKVToolNix GUI: the GUI will no longer automatically resize the columns in tree and list views to match the content size. Instead it remembers and restores the widths set by the user
- MKVToolNix GUI: multiplexer: the chapter name template will now be set automatically to the name template in the preferences' "chapter editor" section. Additionally the option `--generate-chapters-name-template …` will be passed to mkvmerge in situations when mkvmerge will generate chapters (either because automatic generation is enabled or if chapters are generated for MPLS playlists)
- MKVToolNix GUI: chapter editor: if the chapter name template is empty, chapters will be generated without names
- MKVToolNix GUI: chapter editor: added an option to remove all chapter names to the "additional modifications" dialog

Bug fixes:
- mkvmerge: Matroska reader: fixed wrong timestamps when appending Matroska files where the second Matroska file's first timestamp is bigger than 0
- mkvmerge: MP4 reader: fixed division by zero errors during file identification if the timescale is 0 in the `MVHD` atom
- mkvmerge: Windows Television DVR files are now recognized as an unsupported file type. This prevents mis-detection as MPEG-2 with an accompanying flood of error messages
- MKVToolNix GUI: info tool: under certain circumstances "cues" were shown at the wrong level (inside the previous master element instead of on level 1)
- MKVToolNix GUI: job queue: fixed invalid memory handling and consequent crashes when using the "edit in corresponding tool & remove from job queue" option if one of the files in that job contained attached files

Build system changes:
An AppStream metadata file will be installed in `$prefix/share/metainfo`
