What's new in this version:

- mkvmerge, MKVToolNix GUI multiplexer: AC-3, DTS, TrueHD: added an option for removing/minimizing the dialog normalization gain for all supported types of the mentioned codecs
- mkvmerge: AV1: added support for reading AV1 video from IVF, WebM and Matroska files
- mkvmerge: FLAC: mkvmerge can now ignore ID3 tags in FLAC files which would otherwise prevent mkvmerge from detecting the file type
- mkvinfo: the size and positions of frames within "SimpleBlock" and "BlockGroup" elements are now shown the same way they're shown for other elements (by adding the `-v -v` and `-z` options)
- MKVToolNix GUI: multiplexer: added options for deriving the track languages from the file name by searching for ISO 639-1/639-2 language codes or language names enclosed in non-word, non-space characters (e.g. "…[ger]…" for German or "…+en+…" for English)
- MKVToolNix GUI: info tool: implemented reading all elements in the file after the first cluster. Only top-level elements are shown; child elements are only loaded on demand
- MKVToolNix GUI: info tool: added a context menu with the option to show a hex dump of the element with the bytes making up the EBML ID and the size portion highlighted in different colors. In-depth highlighting is done for the data in `SimpleBlock` and `Block` elements
- MKVToolNix GUI: chapter editor: added an option to remove all end timestamps to the "additional modifications" dialog
