Have a random snapshot! In this snapshot, we've replaced the random number generator used for world generation, which makes more seeds come out as different... but it also moves everything around in the world, so expect all worlds to look different in this snapshot.

Another thing that we've replaced is the cubemap - the spinning image that you see behind the main menu. It's pretty sweet!

Also, in case you missed it, we're having our annual Minecraft Live event this Saturday. Make sure to check that out!

We still highly recommend backing up your world before loading it in this snapshot.
