MuseScore 2 significantly improved the typesetting quality to make scores attractive and easier to read. Improvements cover many items such as beam slope, stem height, layout of accidentals in chords and general note spacing. However, this means that sheet music made with MuseScore 1.x looks slightly different from sheet music made with 2.x.
It also means that scores saved with 2.x won't open with 1.x.
To prevent you from accidentally overwriting your 1.x scores, 2.x treats them as an import, which means:
