I checked last night, and there's also:
A separated chat system where instead of everything being Username or Character Name, you can choose Local to be one, the other, or both--and the same with General. Also, you can turn the Arrival chat off. Groups also now has a search button--one we very dearly needed. And the music is awesome! Plus, when entering a map, the name of it pops up on the screen then fades away. I think they fixed Group chat... but I am not sure. I didn't quite test it, but I noted that it didn't pop up at all last night LOL
