Hey
I’ve downloaded a patch release for unity and it had the symbol p at the end
5.3.4p1
what does it mean ?
I have a guess which is “Patch Release” but what’s the difference why not put it “f” as they always do as final or cause it can always be up for changing ?
Just curious 
Thanks
“p” means patch version. Unity releases patches every week.
“f” means final release, it isn’t released as often and they use to Quality Test more deeply.
You should only use patch versions if they contain the fixes you need. Otherwise you should better work with final release versions.
“p” does stand for patch. Is used because the patch release might not be stable, and the “p” indicates that this is the case. Unity will generally recommend that you only use patch releases if you are having difficulty with the stable version.
Basically, it’s a quick indicator to let you know the state of Unity. What version and how stable.
