Endermen will not be near as hostile once you update Minecraft to 1.5.2 today. Well, at least he will no longer get pissed off and take things out on you should he take environmental damage. He’s been given a sedagive. Other fixes include tamed wolves and cats no longer despawing just because they feel like it, and Anvils are no longer feeling generous and have stopped providing services for free. Some other things have been fixed as well, and PCgamesN has the low down here.
