What is Cmeu in an npn BJT operating in saturation mode ?

I know Cmeu is parasitic capacitance in active mode. It's the B-C junction capacitance. But does it change when the npn is operating in saturation mode?
Also in general(not just in saturation mode) what happens to Cmeu at increasing Vce? Does it increase? What other things happen to the capacitance when we increase temperature ?

This is in active mode. If it's in saturation, Vce is almost zero. So it acts like a short. But does it affect the capacitance?
