      </ul>
  <p>

      <ul>
!     <li>OpenBSD now includes <a href="http://man.openbsd.org/?query=npppd&amp;sektion=8">npppd(8)</a>, a server-side daemon for L2TP, L2TP/IPsec, PPTP and PPPoE.
!     <li>New standalone <a href="http://man.openbsd.org/?query=tftp-proxy&amp;sektion=8">tftp-proxy(8)</a> to replace the old <a href="http://man.openbsd.org/?query=inetd&amp;sektion=8">inetd(8)</a>-based implementation.
!     <li>SNMPv3 supported in <a href="http://man.openbsd.org/?query=snmpd&amp;sektion=8">snmpd(8)</a>.
!     <li><a href="http://man.openbsd.org/?query=bgpd&amp;sektion=8">bgpd(8)</a> is more tolerant of unknown capabilities when bringing up a session (logs a warning rather than fails).
!     <li><a href="http://man.openbsd.org/?query=bgpd&amp;sektion=8">bgpd(8)</a> now handles client side of "graceful restart".
!     <li><a href="http://man.openbsd.org/?query=bgpd&amp;sektion=8">bgpd(8)</a> can now filter based on the NEXTHOP attribute.
!     <li>A stratum can now be assigned to hardware sensors in <a href="http://man.openbsd.org/?query=ntpd&amp;sektion=8">ntpd(8)</a>.
!     <li><a href="http://man.openbsd.org/?query=authpf&amp;sektion=8">authpf(8)</a> now supports the use of per-group rules files.
!     <li><a href="http://man.openbsd.org/?query=ftp&amp;sektion=1">ftp(1)</a> client now supports basic HTTP authentication as per RFC 2617 and 3986 like "ftp http[s]://user:pass@host/file".
!     <li><a href="http://man.openbsd.org/?query=ftp&amp;sektion=1">ftp(1)</a> client's mput command allows to upload a directory tree recursively using the -r switch.
!     <li><a href="http://man.openbsd.org/?query=relayd&amp;sektion=8">relayd(8)</a> has various improvements including additional scheduling algorithms (least-states, for redirections, and random/source-hash, for relays).
!     <li>The <a href="http://man.openbsd.org/?query=iked&amp;sektion=8">iked(8)</a> IKEv2 daemon supports NAT-T. (The isakmpd daemon for IKEv1 has supported this for a long time).
!     <li><a href="http://man.openbsd.org/?query=iked&amp;sektion=8">iked(8)</a> blocks IPv6 traffic unless there are v6 VPN flows; this is to prevent leakages as described in <a href="http://tools.ietf.org/html/draft-gont-opsec-vpn-leakages">draft-gont-opsec-vpn-leakages</a>.
      </ul>
  <p>
  
! <li><a href="http://man.openbsd.org/?query=dhclient&amp;sektion=8">dhclient(8)</a> improvements:

      <li>dhclient-script eliminated, all configuration is done with ioctl's and routing sockets.
      <li>interface configuration is much faster.
!     <li>HUP signals cause dhclient to restart; making it re-read the <a href="http://man.openbsd.org/?query=dhclient.conf&amp;sektion=5">dhclient.conf(5)</a> and <a href="http://man.openbsd.org/?query=resolv.conf.tail&amp;sektion=5">resolv.conf.tail(5)</a> files, and obtain a new lease.
      <li>INIT, USR1, USR2 signals cause dhclient to exit after attempting to remove routes and addresses it configured.
!     <li><a href="http://man.openbsd.org/?query=resolv.conf&amp;sektion=5">resolv.conf(5)</a> is written only when the in-use default route was inserted by dhclient. Possible changes to the default route are detected and cause dhclient to write out resolv.conf when appropriate.
      <li>interface hardware address changes are detected and cause dhclient to restart.
      <li>dhclient.conf directive 'ignore' and command line option '-i' added, allowing the suppression of specific options offered by server.
      <li>'-L' command line option added, allowing the creation of a complete record of the most recent offer and what we modified it to when binding the lease.
