carp compatibility 4.0 - current

[Csillag Tamas]

Hi guys,

I have a two redundant OpenBSD firewalls with carp. Both is version 4.0.

I am planning to upgrade the one in the BACKUP state to -current and a
few days/weeks later the other one. But I am wondering if is there any
change in pfsync or carp protocol which will force me to upgrade both at
the same time to retain a proper failover capability.

IIRC simmilar change happend at 3.8, that's why I am asking.

Thanks in advance,
   cstamas

You'll have to ask someone with more knowledge, but I don't recall
seeing any big changes. Although I seem to recall someone proposing to
change advskew or something like that, I don't know what became of that.
