Working perfectly...then you've answered you own question.
Latest and greatest all wonderful but best to look at release notes first and see if there is something fixed or added that you will find beneficial.
However in my experience upgrades several months old (as most recent release is) would have been pulled (or fixed) if problematic. So I would be happy to upgrade just to stay current. Still read the release notes for your model (always)!
Also from a cursory glance the latest standalone upgrade is a 258MB download (with numerous files covering all current APs).
Standalone AP Software 100.1.0.0.194 (All APs) don't see any text files in there.
