differences between pf and upstream?

[Jeremy C. Reed]

Does FreeBSD have any list of differences between pf and OpenBSD's pf?

Or does it all work and behave the same (at least up to last version
imported)? (So same version of PF behaves the same on both platforms?)

Or should I look at all the differences in pf up to OpenBSD's 3.8 version?

It looks like 3.7 is in FreeBSD 6.0 and 3.5 is in FreeBSD 5.x.

The pf chapter in the handbook should update the "warning" to mention the 
version for FreeBSD 6.0 also.

I am hoping to work on the OpenBSD's PF guide to also mention FreeBSD and 
note which items (new features) are specific to OpenBSD. Does anyone know 
if that documentation has been worked on before for FreeBSD?
