Minecraft Snapshot 13w10b released, 1.5 Prerelease tomorrow

Minecraft 1.5 is rapidly approaching us, but with the only confirmed date to be 'March 2013' we don't know for sure when it's coming out. What we do know is that a snapshot came out today, and the Minecraft 1.5 Prerelease will come tomorrow. This snapshot is purely bug squashing to prepare for the big Redstone Update, with some updates like fixing furnace crashes, named mobs, getting in a minecart with a mob no longer crashes the game, and much much more. You can see the full changelog and download at the source link.
