The huge 'Adventure Update' for Minecraft is now official out and ready for downloading.
You might already have it after the game was "leaked" via the official site - which sort of isn't a leak really, is it? - a few days ago.
The update brings Minecraft up to version 1.8, allowing players to set off on an epic quest into the wide open world, killing kill sheep and collecting random things. Or something.
There are two videos all about it through here, if you're curious.
