Minecraft snapshot 12w30a released ahead of 1.3 update

With the Minecraft 1.3 update set to go live on August 1, Mojang has plans to release one or two more snapshots beginning with today's 12w30a update.

The 1.3 pre-release will be available by Wednesday or Thursday.

"The pre-release is intended to be identical to the official release next week, in order to give modmakers and server admins a week’s head start," lead developer Jens Bergensten explained. "That’s why we need to do a snapshot first, since we can’t do changes to the update after the pre-release is out."
