Of note to the engravers here (particularly John R):
- Fixes to issues with Divisi/Unison at system end
- New option for fingering positioning
- Slur adjustment
- More options for Cues, Instrument Changes
- Additional Engraving Options for accidentals on ledger lines, ties on chords, etc, etc.
...and a new Orchestral sample library, plus playback for fermata, breaths and continuous gliss.! There's also new 'humanized' playback effects for polyphonic instruments, e.g. keyboards.
