+pf is one of the firewalls included in FreeBSD, and is probably the most popular.
+pf was created by the OpenBSD project and subsequently ported to FreeBSD.
+
+==== backport OpenBSD syntax
+
+Kajetan introduced the OpenBSD syntax of "scrub" operations in "match" and "pass" rules.
+Existing rules remain supported, but now OpenBSD style "scrub" configration is also supported.
+
+==== pfsync protocol versioning
+
+The pfsync protocol version can now be configured, allowing for protocol changes while still supporting state synchronisation between disparate kernel versions.
+The primary benefit is to allow protocol changes enabling new functionality.
+
+==== pfsync: transport over IPv6
+
+pfsync traffic can now be carried over IPv6 as well.
+Naman finished the work started by Luiz Amaral.
+
+==== SCTP
+
+There is work in progres to support SCTP in pf.
+That support includes filtering on port numbers, state tracking, pfsync failover and returning ABORT chunks for rejected connections.
