Q:

What's new in Unity 2D 5.2?

I've really enjoyed using Unity 2D 4.12 in 11.10. It's very fast, and it works better with some games than Unity (because of Compiz). In Precise Pangolin, I notice that the new version is 5.2. Can someone provide information about user-visible changes between the two versions? 
(I didn't notice until afterwards that the version was released only half an hour before I asked. That's completely accidental :))
