Nodebox piston pushers! Fix a few piston bugs such as pistons pushing pistons, pistons pushing blocks into pushers causing blocks to get deleted, and many more. As a side effect, players can no longer simply walk through piston pushers. Additionally, pistons will only remove their own pushers, and not those of neighboring pistons as well. Remove ENABLE_PISTON_ANIMATION option (not compatible with nodebox piston pushers).
