32.3 is from late August, at least 2 major versions (36.x and 40.x) behind....teslafi says only 0.8% of the fleet is still on 32.3 so no you're not up to date.
As of this post just under 1/3rd of the fleet is on 40.3, another just under 1/3rd on 36.11, a bit under 20% on 36.16, a bit under 10% on 36.10... 6% on 36.3.1...and the rest all scattered on other versions under 1% each
(disclaimer- teslafi doesn't cover the entire fleet, but it's probably a decent general idea of what's going on)
