Major rewrite by Henning Brauer, shrunk the code, made it faster, plus
nat-to, rdr-to, binat-to options for pass or match replaced nat, rdr, binat translation rules
route-to, reply-to, dup-to and fastroute became filtering options
routing domain translation
storing and loading state table to/from file
divert(4) sockets
Downstreams have been slow to pick up - as of June 2015, FreeBSD and friends stuck at approx. OpenBSD 4.5 code.
