Do I need to upgrade from .400 to use new quiet props?

Do I need the latest firmware to use the new quiet props?

I'm currently running .400 on an original Mavic Pro. I know ESC doesn't apply to the original version but wasn't sure if other flight dynamics were different enough that firmware update was necessary.

Unlikely, they might have made subtle tweaks in firmware since the start to improve stability or something, but it's still going to run perfectly OK on the new version.
