I’ve been on it personally, as well as the whole shop, since it was released. No huge issues.
One weird issue though. On one machine there’s a conflict with Dropbox, which required uninstalling Dropbox on that Mac. The same Mac also has some intermittent issue with Project Locking, so I have to run that Mac with locking disabled. Neither are showstoppers. Adobe is aware of both issues, but to date there’s no fix.
Overall, I like the updates, including the change to captioning in Premiere Pro. That’s a HUGE improvement. If you do a lot with closed captions, then you really should upgrade.
