Version 71.0.0 "Altitude" 2022-10-08

New features and enhancements

• mkvmerge, MKVToolNix GUI's multiplexer: added support for the Emphasis audio track header element via the --audio-emphasis option. It is also read from Matroska files.
• mkvmerge: the options --list-stereo-modes and --list-audio-emphasis have been added to list all support numerical & textual values for the --stereo-mode & --audio-emphasis options.
• mkvpropedit, MKVToolNix GUI's header editor: added support for the Emphasis audio track header element via the emphasis property.
• MKVToolNix GUI: multiplexer: when the track properties are configured to be displayed in a tab widget below the files & tracks in the "Input" tab, the "Color information" tab will be laid out in two columns. This reduces the minimum height the whole tab widget requires. Implements #3401.
• MKVToolNix GUI: greatly sped up closing the preferences dialog by only re-running certain initialization functions when their corresponding settings have changed. Also fixes issues such as #3406.
• mkvinfo, MKVToolNix GUI's info tool: added support for the following new elements from Matroska v5: Emphasis audio track header element; Chapter Skip Type; Edition Display; Edition String; Edition Language IETF.
• mkvmerge, mkvpropedit: added support for the following new chapter elements from Matroska v5: Chapter Skip Type; Edition Display; Edition String; Edition Language IETF. The GUI's chapter editor will receive support for them in the next release.

Bug fixes

• mkvmerge: Ogg/OGM reader: mkvmerge will now correctly skip tracks of unsupported types as well as tracks for which all track header pages haven't been found. Fixes #3394.

Build system changes

• libEBML 1.4.4 & libMatroska 1.7.1 are now required.

Version 70.0.0 "Caught A Lite Sneeze" 2022-08-14

New features and enhancements

• MKVToolNix GUI: the user can now control where the job queue files & the preferences INI file are stored via environment variables. If set, the variable MKVTOOLNIX_GUI_STATE_DIR can point to a directory where the GUI stores both the job queue sub-directory and the preferences INI file. If you only want to relocate the preferences INI file, you can store the desired file name for the INI file in MKVTOOLNIX_GUI_CONFIG_FILE. Implements #3382.
• MKVToolNix GUI: when adding directories via drag & drop/copy & paste the GUI will now offer the user the option to create one multiplex settings tab per directory & adding all files from that directory to the corresponding, newly created tab. Implements #3371.

Bug fixes

• mkvmerge: AV1 OBU parser: fixed identifying files that only contain single frame. Fixes #3380.
• MKVToolNix GUI: multiplexer: when reading color parameters from identified files that are floating point numbers (minimum/maximum luminance, projection pitch/roll/yaw) the numbers will be formatted in floating-point notation instead of scientific notation as mkvmerge only supports the former. Fixes #3368.
• MKVToolNix GUI: multiplexer: color parameters that are floating point numbers (minimum/maximum luminance, projection pitch/roll/yaw) will only be set to a value during identification if the identification actually contains the property, and not to 0 anymore if it doesn't.
