# Version 79.0 "Funeral Pyres" 2023-08-23

## New features and enhancements

* mkvmerge: AV1: added support for reading Dolby Vision from AV1 IVF & OBU
streams. Patches by Quietvoid.
* mkvmerge: MPEG TS reader: added support for colors in teletext
subtitles. Patch by Angela Schmid.
* MKVToolNix GUI: multiplexer: when adding files the GUI can automatically
enable the "forced display" flag for subtitle tracks if the file name
contains the word "forced" delimited by certain characters
(configurable). This feature is turned on by default. Implements #3586.
* MKVToolNix GUI: multiplexer: added the option `--stop-after-video-ends` to
the dialog for additional command line options. Implements #3594.
* MKVToolNix GUI: multiplexer: when adding Blu-ray playlists the dialog
allowing the user to select the playlist to add will now show audio & video
track properties as well (pixel dimensions for video; sampling frequency,
channels for audio). Implements #3597.
* MKVToolNix GUI: header editor: in order to reduce confusion with users non
that versed in Matroska elements, the naming of the two "language" track
properties has been changed: the old element is now titled "Language
(obsolete)" & the current, IETF BCP 47 based one is simply called
"Language".
* MKVToolNix GUI: preferences: you can now use the "delete" key to remove
entries from simple list widgets for strings (e.g. the list of recently used
destination directories).

## Bug fixes

* mkvmerge: DTS reader: if a DTS stream doesn't start with a DTS core but a
sub-stream element (EXSS), the reader will now look for a core. If found,
it'll start processing from there instead of from the start. This fixes the
timestamp calculation if the sampling frequency in the core & in the
extensions are different. Fixes #3602.
* MKVToolNix GUI: multiplexer: the "emphasis" and "stereoscopy" combo-boxes
now have a much smaller minimum width, allowing to make the whole
"properties" pane much smaller again. Fixes #3581.
* MKVToolNix GUI: macOS: when you install the application from the DMG it'll
no longer register itself as an alternate handler for its supported file
types. It seems like this overrode existing associations, forcing people to
change them manually to whatever they wanted them to be. Additionally this
forced the associated file to always be shown with an MKVToolNix icon. The
GUI's own `.mtxcfg` files will still be registered. Fixes #3588.
