You minecraft players out there might have heard that the game is updating to 1.8 soon, which offers support for a new skin file format. You can now create separate arms/legs, and make use of 'hat' layers on top of all surfaces! (not just the head)
We updated skincraft to handle the format. Old skins are still backwards compatible, so don't worry. We also fixed a few bugs and added a couple extra features- such as being able to see the inside surfaces of the model and pulling a skin file directly from a minecraft.net username.
