Howdy,

This update is released mainly due to the fact that FreeBSD-SA-25:12.rtsold[2]
has impact on WAN-facing DHCPv6 connectivity being used, but also offers a
mid-size batch of improvements like CARP VHID awareness for DHCRelay and
a thorough cleanup and improvement pass over the Suricata integration we
have been discussing during Suricon in November.

Of special note is that the captive portal accounting moves back to ipfw(4)
from pf(4) because in larger deployments accounting rules are much faster
this way and the use case of Ethernet-less captive portals such as on top
of WireGuard now work properly again.  The hook for pluggable pf(4) "ether"
rules remains for now but will be removed in 26.1 as we do not intend to
advocate its use.

Also, Python has reported security issues of which a DoS in http.client could
potentially affect existing installations given that an HTTP server sends
a malicious response which "can consume a large amount of memory and CPU time
and cause swapping".  Python has not released an update for version 3.11 at
this point in time.
