MKVToolNix v70.0.0 released

A new small release is ready, mostly fixing two annoying bugs in the GUI’s handling of color parameters that unfortunately slipped in in v69.

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. #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 it.

Build system changes

• Several merge requests where accepted that improve compilation on MSYS2 on Windows. Note that this build type isn’t supported.
