No, it isn't. 9.1 is old--over three years old, in fact. 9.3 is less old--just under two years old (9.2 happened in between, but I didn't make a note of the date, and don't care enough to go back and check it--check out download.freenas.org if you care). 9.10, which is not the same as 9.1 (about which
@gpsguy--correctly, as it turns out--surmised that you were confused, whereupon you decided to get snarky), is newer--about six months old. 10 > 3 > 1. Yes, 9.10 is numerically equivalent to 9.1. No, they aren't the same thing. Yes, that's confusing, though iXSystems aren't the only ones to do this.
I thought this was pretty clearly laid out in
this post of mine--what part of it was unclear?
