The main thing is Stereo Usertracks (previously they were always mono). btw, that feature wasn't part of the original release but is a free patch available later today Dec. 3, and is part of the shipping/download installers.
Now that we've got the release launched, we can address some more UserTracks Wishlist items - to be included in future 2016 free patches.
High on the list is
- shots/holds ...
- fix for waltzes (rodipoet reported)
any other UserTracks suggestions welcome.
