mkvmerge: sorting tracks by type did not work properly when some tracks weren't copied - mkvmerge: track numbers in the destination file were assigned out-of-order when the track order in the source files differs from the one in the destination file. This fixes the programs not catching an exception from the `boost::filesystem` library which doesn't cope with mis-configured locale systems well. If neithe of the three succeeds, an error message will be shown, and the program will abort. if environment variables such as `LC_ALL` have been set to`fr_FR.UTF-8` but the locale for `fr_FR.UTF-8` hasn't been built, MKVToolNix will try to fall back to `en_US.UTF-8` first & `C.UTF-8` second. Also added an installation check for the same issue Fixed: - all: Linux: if initializing the locale system based on the system's settings fails, e.g.

This fixes some installation issues that could occur when a user extracted a portable app archive into a folder like `C:Program FilesMKVToolNix`. Windows installer: the installer will now remove the file`dataportable-app` if it's present in the installation directory as its presence would signal to the app to run in portable mode, requiring write access to its base directory. The oldest Debian coming with this version is Debian10 'Buster' for Ubuntu it's 18.10 'Cosmic Cuttlefish'. This means that the minimum glibc version this AppImage is compatible with has also been bumped, to v2.28.

New features and enhancements: - MKVToolNix GUI: header editor: for files that only contain legacy track language elements but no IETF language elements the header editor will now derive the IETF language elements from the legacy elements - AppImage: the AppImage is now built on AlmaLinux 8 with Qt 6.5.1.
