It seems like just an basic update not a new world or such. Sadly the pet training is broken at the moment which is one of the main things I want to do when I get into test realm. (Nothing like a sneak peek at what talents your pet will get)
Check it out as they have a few things to test including new maps, panther mount and housing signs etc. So get out there and test those pathways and bridges and make sure its safe for the new wizards!
See you there,
