Sorry, news about the game have been rare in the last few weeks...

Worth waiting...? :)
Starting in the next version, when you'll detach a small group of blocks from a planet or a vehicle, it will be subject to physical forces, and will fall on the ground.
If one of those groups of blocks is not modified for a while, and if it is not made into a vehicle by attaching a gyrograv block or an aeroblock to it, it will eventually be destroyed.
