I'm asking in light of the recent vulnerabilities that we're seeing, but also just in general. I just updated my 80F to 7.2.7 (the 'mature' firmware, whatever that means). I see the option to upgrade ...

I think the 7.4 line was marked as mature at least back to 7.4.4 as well, but I notice they still show 7.2 being the recommended line on most devices per the recommended software link on that firmware ...
