What is the difference between the pixhawk 2 cubes?

i used to own a pixhawk with “Pixhawk 2 CUBE” written on it. now the company changed the pixhawk, and i got one that has just “CUBE” written on it.
any idea why they made the change? is there anything different about them at all besides design and size?
thanks in advance

Good day,
it depends on the canopy color… the cube orange is mcu stm32h753…the the yellow is mcu stm32f777, pink and blu is stm32f427…, after this different imus… sensors
