PCM not showing firmware version number--what now?

I'm a new owner of my first Porsche--a Cayman. In playing around with the PCM (which I've read is finicky and not well-supported by Porsche), I've learned that my hardware does not display which version of firmware is installed. It just shows "V" for version and no number after that. Though I know updates stopped some time ago for my car I'd like the firmware to be up-to-date as possible. If I take the car to a dealership, I may spend $200 just to find out that the firmware is up-to-date after all.

So my questions are:

1) Is there another "secret" way to figure out firmware version (maybe a certain feature that was added in the latest update that I can check for), or another sub-sub menu to unearth? 

2) Is the firmware update something I should probably just leave alone and not worry about? I know that question is subjective, but perhaps firmware updates are not all that they are cracked up to be with the PCM.

Thank you for your assistance.
