Just writing this comment to document known issues with this update:
0.2.7 broke the demo world, board stacking, and system compatibility. Pipe01 never updated PiTung to work with 0.2.7, so there aren't any mods. But it has some lifted limits, and better performance, and the other stuff mentioned in the changelog. It's useful to have both installed for large projects, IF it even works on your computer.
