Bones added as a drop (possibly only from skeletons) and can be crafted into Bonemeal
New grey, light grey, and black sheep, which all drop correspondingly colored wool
Tools now provide more uses before they break
Sand can now make a block that looks like sand, but acts like stone, appropriately called Sandstone
Bugfixes:
Paintings work in multiplayerDisconnecting while riding no longer keeps the player in the world
More state is properly synced in multiplayer
Fixed colors going weird on PowerPC
Fixed a chunk reload loop in singleplayer
Fixed most lighting bugs in newly-generated survival multiplayer maps
Fixed a few crashes on load level bugs
Falling sand behaves better in survival multiplayer
Jack-O-Lantern has correct tooltip
Things that may or may not be legitimate and need further confirmation:
Players can not only dye wool, but dye actual sheep
The deeper underground the player is, the shorter distance light travels
Players can now make charcoal, which acts as regular coal and lasts equally as long, by cooking wood in a furnace
Bonemeal can be used as fertilizer by right-clicking the bonemeal onto, for example, planted wheat or saplings, and it causes instant growth of said crops. Larger items, like trees, require more bonemeal than smaller items
Spiders can now climb up walls
