MuseScore 1.0

There is no release date planned. However, there are a few issues which needs to be resolved before 1.0 can be released:

1. a fully functional and stable Mac release
2. the musescore rebranding project needs to be finished. This will result in a logo, wordmark and promotional material to support the 1.0 release.
3. no critical issues in the bug tracker

I hope this answers your question.
