WoW Cataclysm 4.0.1 patch: Talent treeThe old talent tree was a single pane with three tabs -- one for each of the talent specs. Also, it had "51-point" talents (meaning, the last talent in the tree required 50 points to be spent in that tree). The new talent tree is a single tab with three panes so that all three trees can be seen simultaneously. In addition, Blizzard has shortened the trees to "31-point" trees and required the player to put 31 points into a tree before they are able to spill over into another tree.
