Just because I haven't seen anyone mention it, anyone else notice that the "who" tab in the social panel no longer auto populates? It stays blank until you hit the search button. Once you search once it will stay populated and continue to update the list.
Although you can clear it again by unchecking the "any" box and search for no classes.
Interesting little fix there, wonder if it will help some of the clientside lag? I have noticed the loading time when logging in or changing instances is a little quicker...for me at least.
