Greg attached the following warning:

Helium, Molten Tin and Molten Sodium as a reactor coolant has been buffed, your old reactor designs using these coolants might be able to "explode" (reactor explosions are still disabled, they will just delete their inventory) when running. Shut those reactors down before updating and evaluate that they will explode before turning them back on. Reactors running other coolants are not in danger of exploding, but might not produce as many neutrons as before.
