You might have seen on tUGS or in the vault that the first release of the GCE Core Rules are now available. There's not many changes at the moment although as we all find them (you included!) we'll be amending the document. Current changes: Artillery dice are gone. Scattering weapons now use a D6. Weapons that do multiple damage now do multiple points of damage to vehicles. Warriors on overwatch may use sustained fire weapons. Warriors thrown overboard after losing a boarding action now don't scatter when they're thrown overboard.
