+man:pf[4] now supports the OpenBSD style NAT syntax.
+It is possible to use "nat-to", "rdr-to" and "binat-to" on "pass" and "match" roles. The old "nat on ..." syntax can still be used.

+The man:pfsync[4] protocol has been updated to synchronize multiple missing attributes.
+This fixes synchronizing of states with route-to, af-to, rtable, dummynet, tags, and scrub options.
+If synchronization with an older version of FreeBSD is needed the protocol version can be configured with `ifconfig pfsync0 version $VERSION` where $VERSION is 1301 for 13.X relases or 1400 for 14.X.
+It defaults to 1500 for synchronization between hosts running FreeBSD 15.0.
