The latest major update to Minecraft, aka the Redstone Update, came out yesterday? Mojang isn't taking a break however, and today another snapshot has been released. This week's snapshot doesn't add any new features since it's a snapshot of Minecraft 1.5.1. Bug fixes include Enderdragons can now break blocks again, combining enchanted books, paintings not being placed, and a few more. You can get the snapshot and the full changelog at the source link below.Source: Mojang
