Translation switched to another release
> I'm told that the translation was switched to another of the MantisBT branches
For the record, this occured when MantisBT 1.3.0 went live and we created a new master-1.3.x branch to support the new stable release, while the master branch moved on with new development towards 2.0 release. TranslateWiki was previously configured to update master, but we did not inform you of the change in a timely fashion.
All translation updates should go to the master-1.3.x branch. The MantisBT dev team does not commit anything to language files, other than the original strings_english.txt.
