Hello beautiful free-and-libre audio people! I'm happy to announce the new release of jack_mixer version 16! jack_mixer is a GTK+ JACK audio mixer app with a look & handling similar to hardware mixing desks. You can find the project's homepage at: https://rdio.space/jackmixer/ The new release is also available on GitHub at: https://github.com/jack-mixer/jack_mixer/releases/tag/release-15 New Features: * Internationalization (i18n) support was added, making GUI labels and messages and the command line help translatable. * A German translation was added. * A French translation was added. * A global language setting was added to the preferences. * French and German translations of the application description were added to the XDG desktop file. Fixed: * Some global settings where not properly persisted in the settings file when changed in the preferences dialog (#124). * Selecting a custom default project path in the preferences dialog via folder selection widget did not update the path in the text entry. * The message formatting in error dialogs was corrected and when an error dialog is shown, the error message to printed the console now only contains a Python traceback when the debug option is active. * Various debug log messages received minor fixes and improvements. Documentation: * A man page for jack_mix_box was added. * A new contributing guide was added to repository. * The section on environment variables in jack_mixer's man page was updated and enhanced. * The NSM project URL was updated in various documents.
