Yes, and yes

I've had the beta for a while now and it works (1,76 patch 1 fixed one issue with the sprite animation GUI)
The main "issue" right now is that when creating a sprite collection, font or sprite animation in the new project window, you have to select the directory you create an asset in the right hand side panel - it will create it in the root if you have something selected in the left panel. You can switch to the old style project window, and there are no issues there.
The other is some annoying deprecation warnings - Ill have these sorted in the next release.
There's every chance that there could be more bugs that I'm not aware of, but let me know if you find any - Ill get em sorted.
