AeroPod, PowerPod and Newton

I've been using my Newton with my indoor trainer all winter and have not found the need to analyze the rides.
So when I finally rode outside and analyzed that ride, I was notified that there was new firmware - 4.15 and 4.16.
Version 4.16 downloaded and updated...my question is, do I have to also download 4.15??

thanks

No. Each successive version of FW contains all the updates from all prior versions of FW.
