Isc-dhcpd v 3.0.5 and 3.1.0 incompatible?

I¹ve been trying to make failover work with a new master server (a small
DS107+ box (google it)), which comes with 3.1.0, and a freebsd server which
only has 3.0.5 in ports collection (pre ported to freebsd).

My question: is there known problems that will force me to compile 3.1.0 on
the freebsd, or is this something new:

Once I bring up both boxes, with config thats worked fine with the previous
server (3.0.4) the freebsd (3.0.5) dumps core:
