Time for a new snapshot! One big difference this time is that you don’t need the server jar to play single-player. Also,

• Villagers will trade items (they are cheap bastards, though!)
• Added a “currency item”
• A few minor terrain changes
• A new useful block/item (requires obsidian)
• Added a /seed command for showing the map seed
• Added sandstone stairs
• A lot of smaller changes and fixes
