We have good news to share! As development of MuseScore 2.0 is nearing the final stages, the time has come to start localising MuseScore. The more translations we can ship 2.0 with, the more people will enjoy the ability to notate music.
There have been quite a few changes in the translation workflow since the 1.x series. Basically it is more simple than before and you can instantly check out your translation work in MuseScore.
