It now also detects the type of bitstream framing (ISO 14496-15 vs. HEVC dumper development tool: the tool has been renamed to `xvc_dump` and extended to be able to dump AVC/H.264 bitstreams, too.

The setting will be auto-corrected by the GUI if the settings file were saved last with a version between v60.0.0.0 & v60.0.0.17 & 'lowest' & it is still set to 'lowest'. v60 changed that to 'lowest', which turned out to be much slower on Windows for no real gain over 'lower'. Up to and including v59 the default was the 'normal' process priority. MKVToolNix GUI: multiplexer: the GUI now defaults to the 'lower' process priority setting for new installations in order to leave more room for other applications, especially interactive ones. MKVToolNix GUI: multiplexer: deriving track languages from file names: the default list of boundary characters now includes `-` MKVToolNix GUI: multiplexer: deriving track languages from file names: the GUI can now detect full BCP 47/RFC 5646 language tags in file names. `-stracks !es` would get rid of all three tracks, not just the one for the generic Spanish. Similarly inverting the selection with e.g. `-stracks es-MX` which would only match one track. For example, if a file contains three subtitle tracks with languages `es` (generic Spanish), `es-MX` (Spanish as spoken in Mexico) and `es-ES` (Spanish as spoken in Spain), the user can use `-stracks es` to match all three tracks or be more specific with e.g. This means that only those components (language, region etc.) the user specified will be required to exist and be equal. mkvmerge: track selection: when using language tags for selecting which tracks to keep, mkvmerge will now use component-based language tag matching instead of comparing them verbatim.
