Very solid here. Only thing I noticed was the quick grouping feature for picking colors on multiple tracks isn't working. (A small detail in my opinion) other than that, Friday I managed an 8 hour session with stellar results.
I didn't notice an increase in high performance or anything, but I have not noticed a change in stability.
I also haven't noticed any of the mouse pointer issues others have seen (I consider myself lucky).
All in all though, runs just as smooth as last months update and that one ran great.
