Because 1.7 just came out and people are already tired of it, here's two new pics from 1.8.
NPC village with giant mushrooms
Ruins with new stone brick blocks
Notch also said that there will be a new biome code, and that the giant mushrooms are for a new type of biome and the wont appear randomly in the world. I wonder if this means that we'll see the same sort of chunk errors that came about with the halloween update? Here's hoping that biomes are bigger this time.
