Yes. The 6.2.1 update fixed the constant crashing I was seeing.
Full screen mode (the shift-F one that goes between 3 modes) now works as well.
These were the two biggies I was seeing. I'm on OS X 10.11, which is where most of the problems were I think. I don't believe the crashing fixed by this update was common for people on 10.10.5 or earlier.
