MuseScore 3 Changes
I have created a document in Google Docs to make it easy to share information about what is changing in MuseScore 3:
It's still a work in progress, but I think I have most of what's new listed, if not in any detail. Take a look, leave comments there or here if you see things that are missing or have other feedback. At some point, we will probably want to move this to a page here on musescore.org so it can be edited with all the usual site revision control, but I figure that can wait until it matures a little.
