Other features:

• 
  
  Swamps: darker colored water and lily pads
  
  

The shade of the water seems to depend on the biome the water is located in: If you pour "swamp water" into a non-swamp biome, you get normal-shade water. If said water flows from a non-swamp biome into a swamp biome, it changes colour at the biome border.
Red flowers and Snow Biomes are back!
Mushroom Biome! purple tinted grass and large mushrooms growing.
Mooshroom" cows appear in Mushroom biome, can be sheared to get mushrooms and then turn into regular cows
Snow "Golem"- can be crafted by placing two snow blocks vertically on the ground, and then placing a pumpkin head on top of them. NOTE: They are crafted by block placement not a crafting square!

Rain is re-textured.
Water and Lava leak through adjacent blocks.Chests now make no sound at all.Holding space no longer allows sustained jumping; must tap jump key for each jump. Holding jump key is being re-enabled by Notch soonLava and Water Interactions: (to be clear)When flowing lava hits flowing water = smooth stoneWhen flowing lava hits still water = smooth stoneWhen flowing water hits flowing lava = cobblestoneWhen flowing water hits still lava = obsidianBug Related:FIXED- Stair lighting issues Except with smoothstone stairsExperience bar changes every time the player jumps (Jeb tweeted that it's not a bug, it "is to test SMP exp orbs... ;)"Swamp water and regular water appearing side by side for bad visuals.Reports of a lot of players having major FPS problems. Lag spikes of death are not yet defeated :(Bow sometimes has extra-long melee range?Swamp Grass blocks have improper grass coloring on their sides.Shearing "Mooshroom" cows gives the "getting wood" achievementShift clicking items when you craft doesn't get tracked in your stats properlyPreexisting light sources (lave, flaming netherrack, etc) might not give off light properly.Add in the comments any other new discoveries!Disclosure: all of this information is coming from comments posted here and pictures in r/minecraft/new. Give others the credit for discovering all this not me!PS: post some of your pics in the comments and I will link them in the main post here for you.
