translator objects now have the following search path: - selected locale messages in the tracker locale dir - selected locale messages in the system locale dir - english messages in the tracker locale dir - english messages in the system locale dir automatically compile .mo files if needed (found .po file and .mo is missing or .po mtime is greater that .mo mtime) removed support for python < 2.0. gettext module is now required. get_translation: removed 'domain' argument, added 'tracker_home' argument
