The crafting system for the mobile interface is called MATTIS, as in the Minecraft Advanced Touch Technology Interface System. All you need to do is open your inventory, choose what you want to make, and as long as you have the necessary components, it's made. Other additions in this update include better AI for zombies, cows and ducks, and descriptions of items in your inventory. We're really looking forward to the next update, though: Hopefully Mojang will put Pockets or Editions in the game next.
