This is a bit strange - I had that same issue between RC2 and RC3.

And there the commit logs show that somebody did explicitely change
the version number (from 1302000 to 1302001), for whatever reasons
I didn't fully grok.

It seems the modules do not like such a change, and have to be rebuilt.

That version number is visible with pkg info:

It is also present in the base installation ...

$ grep FreeBSD_version /usr/include/sys/param.h
#define __FreeBSD_version 1302000       /* Master, propagated to newvers */

 ... and in the kernel source:
$ grep FreeBSD_version /usr/src/sys/sys/param.h 
#define __FreeBSD_version 1302000       /* Master, propagated to newvers */

And somewhere it lingers also in the kernel itself:
$ strings /boot/kernel/kernel | grep 13020
1302000
