+- added dead peer detection which checks aliveness of remote peer if no
+ IKE or ESP traffic is received. Support for dpdaction, dpddelay???
+
+- Added support for leftprotoport/rightprotoport parameters in IKEv2. IKEv2
+ would offer more possibilities for traffic selection, but the Linux kernel
+ currently does not support it. That's why we stick with these simple
+ ipsec.conf rules for now.
+
+- Initial NAT traversal support in IKEv2. Charon includes NAT detection
+ notify payloads to detect NAT routers between the peers. It switches
+ to port 4500, uses UDP encapsulated ESP packets, handles peer address
+ changes gracefully and sends keep alive message periodically.
+
+- Reimplemented IKE_SA state machine for charon, which allows simultaneous
+ rekeying, more shared code, cleaner design, proper retransmission
+ and a more extensible code base.
