Beta version 0.2 is up. With this update you’ll see the start of the new World Map implementation. This allows you to become selective when starting a new settlement. For now, the options are somewhat limited (you basically have the option of choosing the level of terrain undulation and the tree density), but in the future we’ll see this become more robust as the various biomes are added.
Another exciting update is the depth of the local map, which has been increased by 50%. This does, however, break previous saves. I’d suggest holding off on the update until you are ready to start a new settlement, as the new features only apply to new games anyway.
