pfSense 2.8.0 based on FreeBSD 15 came out last May, I thought I'd upgrade mine from 2.7.2 (FreeBSD 14) today. After backing up my configs for both pfSense boxes I went about updating my backup pfSense box first, it was several releases behind so it took a little while (it has to be upgraded one release at a time). Finally it was time to take it to 2.8.0, and the update failed due to the EFI partition being too small. Quickest solution to this per their forums is a fresh install of 2.8.0 and then restore from backup configs. I've had to do that after past upgrade failures which usually only happen when going to a different FreeBSD base. But I don't feel like doing that now so both boxes are staying on 2.7.2 for now.

It's an appliance anyway... it's not like you're salivating for the next KDE Desktop release in the distro upgrade

If it still manages your network the way you want it to, the NAT works and it stops packet tomfoolery, an upgrade is only more likely to annoy you anyway, by changing the UI and things. It is likely just as "secure" for your usage. I mean, it's not like your old version is broken.
