Heh erm ya lots of stuff happened. Yes shamans can drop 4 at once. Yep there is a new 40man bg. Conquest now drops in all heroics. You get 2x Triumph for doing the daily dungeon. There is a new area in Icecrown where you can do jousting dailies and a new 5 man(trial of the champion) and raid is there also.

Coolest change to me is "click to move" in mouse options and then hitting key for slaves that "interact with target" via keybinds. It's amazing, makes all your slaves run to the target and either attack it if its red or open quest dialog/merchant dialog if its green. Makes all melee groups a snap to make sure they are facing the mob/player.
