What's coming for 1.2 in Minecraft and here

If you haven't heard, Minecraft 1.2 is a fairly big update. The major changes include:

• Worlds can now be up to 256 blocks high, double the height of current worlds (!)
• A new jungle biome has been added
• A new ocelot (a feline) mob has been added that you can tame
• Improved mob AI for all mobs; mobs will be able to pathfind and follow you around corners and obstacles!

Unfortunately, these changes (namely the new biome) necessitate a new world because the algorithm has changed. As planned, Vincent and James will be getting a world reset, but with the following caveats:

• James and Vincent may be merged.
• You will be able to keep your items and houses from Vincent, though this will be a manual process where we move your house over from the old world.

At the moment, we have no plans to make any major changes to Alice's world.
