Java Edition 12w34b

12w34b was released to fix some of the bugs and crashes in the 12w34a snapshot.

Additions

 * Added boss names above boss health.

Changes

 * Changed recipes for buttons. They now require 1 stone block/wooden plank to craft.
 * Leather and diamond armor textures slightly changed:
 * Leather armor sleeves are extended by one pixel.
 * Their item texture has been changed to match the new texture.
 * Diamond armor sleeves now have a notch on the inner side.
 * Removed "map_#/#" on the map and added "Map #" in the tool tip
 * When taken down to half health, Withers will gain Wither armor, making them immune to arrows.
 * Occasionally, zombies, skeletons, and zombie pigmen will spawn with the ability to pick up items on the ground.
 * Armor will automatically equip. Items will instantly be held, which is not exclusive to weapons. This means these zombies can be found holding items they have come across, such as rotten flesh.
 * This will cause zombie pigmen to drop their sword.
 * This will cause skeleton to drop their bow.
 * The attribute applied to allow them to pick up items is called CanPickUpLoot.
 * Arrows caught on fire (or by enchantments) are able to ignite TNT when on contact.
 * In the Overworld, Zombie Pigmen are eager to get back in the Nether Portal (e.g., if the player makes a portal and spawns Zombie Pigmen in Creative, it will run into the portal).
