Patch 7.0.3 (2016-07-19): No longer causes the pet to break all loss of control effects or shots to cost 50% less Focus, but increases the hunter's damage by 20% (up from 10%). Using [Dire Beast] now reduces the cooldown, but its cooldown has been increased from 1 minute to 1.5 minutes.
Patch 5.2.0 (2013-03-05): May now be activated when there is no line of sight to the Hunter's pet.

Patch 4.0.1 (2010-10-12): Cost removed and damage bonus decreased to 20%.
Patch 3.2.2 (2009-09-22): The duration of this talent has been reduced to 10 seconds. In addition, hunters with this talent will do 10% additional damage at all times.
Bestial Wrath and [The Beast Within] changed to function like PvP Trinkets, removing any movement impairing effects and giving immunity to these effects for 10 seconds. The tooltip doesn't say this, but it also now breaks all forms of CC that a PvP trinket would break (including Cyclone, Sap, etc.).
Patch 2.1.0 (2007-05-22): The immunity granted by Bestial Wrath now lasts the full duration of the ability. It also now grants immunity to [Cyclone].
