Minecraft Snapshot 12w37a, lots of tweaks included

Not every snapshot can have loads of new features, but bug fix snapshots are just as needed. This week's snapshot has mostly bug fixes but a few new features as well. The first of which is tweaks to the mob boss 'Wither', which is still under heavy work. Carrots have been renamed to 'carrot', Pumpkin Pie has been added, food items no longer have a red outline, the new superflat customization GUI, fishing gets XP, pigs jump when being riden, /clear will clear your inventory, and in hard mode mobs might jump off a few more cliffs than normal. Get the full scoop at the source link below, and head on over to Mojang's site for the downloads.
