Compatibility issues in nightly version
I've just installed 2 new nightly builds which seem to have odd compatibility issues.
Version 1b306e9 on both Mac and Windows and version 12e5cc5 on Mac only.
Both fail to open most of the scores I've created using earlier, recent nightly builds and report them as being made with a "newer version of MuseScore".
Both also report there is an updated version available : "MuseScore 0.9.6.1 r3280. I was alerted to this because opening version 1b306e9 on my Mac for the first time prompted me to update immediately. I wouldn't have expected nightly builds to have an upgrade path at all.
