Upcoming features 1.7
Jeb tweeted an image of a new biome, unofficially dubbed the Redwood Forest. This biome is an upcoming feature in 1.7, and is composed of spruce trees, some of which are 2x2 thick. Mossy cobblestone appears frequently in clusters, and a new block called podzol can be found in this biome. There will also be dirt that will not naturally turn into grass.
The daily dose of Minecraft.
