Addon Interface
Removed restrictions on the player’s secondary resources (combo points, chi, etc) so addons can create custom displays for them.
Added a new smooth-animate option to status bars (health bars, mana bars, cast bars, etc) to allow addons to avoid performance issues.
Added several new APIs requested by addon developers to allow them to display auras and cooldown swipes more easily during combat.
Loosened restrictions on an API that is used by addons to compare units to each other (to check if the player has a particular enemy targeted/focused or has their mouse over them).
Fixed various issues addons were experiencing when showing tooltips while in combat.
Я так понял, живем еще 1 патч, не считая ВА и тогда точно минус аддоны.
