Xelerance has released openswan 2.6.33


This is a major feature and bugfix release.

KLIPS now fully supports IPv6. The OCF codes has seen many improvements
and on SMP machines the AES speed is now roughly 95% of plaintext speed.
An important NAT-T fix resolves some Windows and OSX/iphone issues and
the NAT-T case where both sides are behind NAT. And the ipsec verify
command now checks for a lot more things on your system.

The full change set for this release follows below.
