+strongswan-4.0.3
+----------------
+
+- Added support for the auto=route ipsec.conf parameter and the
+ ipsec route/unroute commands for IKEv2. This allows to set up IKE_SAs and
+ CHILD_SAs dynamically on demand when traffic is detected by the
+ kernel.
+
+- Added support for rekeying IKE_SAs in IKEv2 using the ikelifetime parameter.
+ As specified in IKEv2, no reauthentication is done (unlike in IKEv1), only
+ new keys are generated using perfect forward secrecy. An optional flag
+ which enforces reauthentication will be implemented later.
+
+- "sha" and "sha1" are now treated as synonyms in the ike= and esp=
+ algorithm configuration statements.
+
+
+strongswan-4.0.2
+----------------
+
+- Full X.509 certificate trust chain verification has been implemented.
+ End entity certificates can be exchanged via CERT payloads. The current
+ default is leftsendcert=always, since CERTREQ payloads are not supported
+ yet. Optional CRLs must be imported locally into /etc/ipsec.d/crls.
+
+- 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.
+
+- Added Dead Peer Detection (DPD) which checks liveliness of remote peer if no
+ IKE or ESP traffic is received. DPD is currently hardcoded (dpdaction=clear,
+ dpddelay=60s).
+
+- 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.
+
+- The mixed PSK/RSA roadwarrior detection capability introduced by the
+ strongswan-2.7.0 release necessitated the pre-parsing of the IKE proposal
+ payloads by the responder right before any defined IKE Main Mode state had
+ been established. Although any form of bad proposal syntax was being correctly
+ detected by the payload parser, the subsequent error handler didn't check
+ the state pointer before logging current state information, causing an
+ immediate crash of the pluto keying daemon due to a NULL pointer.
+
+
+strongswan-4.0.1
+----------------
+
- Added algorithm selection to charon: New default algorithms for
ike=aes128-sha-modp2048, as both daemons support it. The default
for IPsec SAs is now esp=aes128-sha,3des-md5. charon handles
simultaneous rekeying. To avoid such a situation, use a large
rekeyfuzz, or even better, set rekey=no on one peer.
+- support for host2host, net2net, host2net (roadwarrior) tunnels
+ using predefined RSA certificates (see uml scenarios for
+ configuration examples).
+
- new build environment featuring autotools. Features such
as HTTP, LDAP and smartcard support may be enabled using
the ./configure script. Changing install directories
listcerts and allows proper load, reload and delete of connections
via ipsec starter.
