It's often the little things that make a big difference. Mojang has released a combat-focused Minecraft update that lets you carry items in both hands, dramatically streamlining how you play. You can carry both a sword and a shield (also new) when you're expecting a rough fight, or place torches while you're digging tunnels with your pickaxe -- no more switching back and forth for some mundane tasks. This may take some time to get used to if you're a veteran, but it promises to make your virtual life considerably easier.
