Update

For those that didn't know, an update for Minecraft came out on Friday, it included Wolves, cookies that are made with cocoa beans which Notch has also brought back in the game they can be found only in dungens and they can dye wool, sleeping in a bed will reset your respawn point (though it hasn't worked for me, so theres a bug that they will probably fix in the next update, you will hang onto a ladder when you stop moving and hold sneak and Mojang AB has done heaps of infrastructure for the stats and achievements.  You may also find on your travels a chest that you hadn't placed, well thats a locked chest and was made as a Aprils Fools joke.  Those are all the major updates, though you can see a whole list here Version History and you can go there anytime a update comes out and they will tell you what changes have been made.
