Does my 8U2 need updating?

On the page "https://www.arduino.cc/en/Hacking/HomePage" there is a link to "Upgrading 8U2 firmware." That page has instructions to find the VID and PID for an Arduino board, but no info on what the acceptable firmware version(s) should be.

Is this info somewhere else in the Hacking link?

I'd say if it's working for you as is don't mess with it. That is unless you want to do it just for the sake of learning/hacking/playing around, then go for it!

Good advice.
