Segun el minecraft forum, la lista de cambios es esta:
-Monster Spawners now support extra information for the mobs it spawns. This allows unmodified games to have spawners for special variants of mobs. The player still requires external or modified means to set these parameters, though. Some examples of what Monster Spawners can spawn are Charged Creepers, Endermen holding specific blocks, Green Robe Villagers, and Villagers with custom trade offers.
- Performance improvement.
- Added crafting recipes for wooden stairs
- Fixed changing the name of a world, loading that world, saving and quitting it undoing the world rename
- Fixed the game crashing when it automatically selects the "Scanning for LAN Worlds" item in the server list and you delete it
- Fixed the arrow representing the player on the map item not pointing in the right direction
-Fixed clicking "Save and Quit" or "Disconnect" twice quickly crashing the game
-Fixed the SMP server fairly regularly dropping all players and showing many NullPointerExceptions in the console every few hours
-Fixed save files being closed each time the world was auto-saved
-Fixed being able to duplicate sand and gravel
-Fixed placing a piston in front of another which is powered, but not extended, causing the placed piston to become broken and have the same texture on all sides
-TNT no longer drops as a ressource on creative mode
-Numerous bugfixes
