Minecraft's beta enters version 1.4, and has brought with it some new bits and pieces. I'm most excited about the idea of a tameable wolf, who can trot about with you, and can even be summoned if he gets too far away. The other big headline in this update is that beds, as we exclusively revealed, will now act as spawn points. I think that's probably the biggest fundamental change the game has seen in many months, and will certainly dramatically effect how the game is played by many. The full list of changes is below. Oh, and be sure to check out the new Minecraft Store, for in-game items, which I think may have opened a day early.
This is the list nabbed by the amazingly diligent folk at the Minecraft Wiki, Minepedia.
Bobbing has changed
New pixelated Minecraft logo (no longer 3D blocks)
Added tameable wolves
Sleeping in a bed now resets your spawn position
Sneaking while climbing will hang on to the ladder
Spiders will no longer trample crops
Sheep spawn in more colors, however rarely. (Brown, Pink)
Movement in flowing water is slower.
Flowers and Mushrooms are more common.
Cocoa Beans can be found in Dungeon chests.
Wheat grows more quickly.
The new default hotkey for the inventory is 'e'.
Wolves will teleport to you if they are too far away from you if it's not sitting.
Added new block, Locked Chest, also known as Steve Co. Supply Chest, same skin as chest, gives Team Fortress 2 type message box when right clicked, emits light, cannot be broken, can be destroyed by explosions.
And then there's the new Minecraft Store if you need keys for your Locked Chest.
