The update is pretty big, and will change a lot of how Minecraft is played, focusing on making exploration and combat much more rewarding, and bringing in a bigger sense of adventure to the game.
Already implemented are new complex terrain features, at least one new mob, some interesting new combat mechanics, a new lighting engine, and some experimental new gameplay ideas. To come is more interesting farming, bigger incentives to explore, and npc villages.
