The new snapshot (Which you can get here www.mojang.com) is a very cool snapshot!

It includes the new Stained Glass (Woop woop!) And Stained Glass Pane. Above is a picture comparing it to the stained clay, and carpet.

That's it for blocks.

Any items? Nope.

BUT, the re-wrote the network code (aka what Minecraft runs on to stay online) with Netty! It actually runs alot smoother now. (Thanks Dinnerbone!)
