Did you get some sort of bug fix list with it? In a readme perhaps?
If not, I know you'll be busy checking out the new toys and stuff, but could you maybe see if they fixed the step sequencer? Just load a preset pattern with any drumkit on a midi track and it should randomly stop playing within a minute or two if it's still broken, otherwise it's good.
Another thing is the groove quantize, does it work now? Does it have any effect on midi notes, or does it just randomly scramble the whole thing like it used to do before they disabled it?
