Diablo III is out now for players in North America, and it's a big one for pets. Area damage now hits pets for less damage than before, some pets have had their health increased, and in general there's a play philosophy focus that pets should be roughly as durable as the class that summoned them in the first place. It's good news if you tend to take part in the game with a companion creature or two.
The update also makes a variety of adjustments to Greater Rifts, altering the behavior of enemies found within the rifts and removing certain maps form the rotation. Witch Doctors have also received a variety of buffs, with several fetishes getting substantially more life and improved functionality. Take a gander at the full patch notes to see how much has changed.
