What exactly do you mean by 10-CURRENT? Head today, head this year, head
since 9 was branched? In any case, check OSVERSION. A great many ports may
be looked at for examples. E.g. graphics/blender. See the FreeBSD Porter's
Handbook 12.6. There is a list of every OSVERSION bump, but I can't
remember exactly where it is, but  to check for 10, check if OSVERSION
>1000000.
