+- initial support of the IKEv2 protocol. Connections in
+ ipsec.conf designated by keyexchange=ikev2 are negotiated
+ by the new IKEv2 charon keying daemon whereas those marked
+ by keyexchange=ikev1 or the default keyexchange=ike are
+ handled thy the IKEv1 pluto keying daemon. Currently only
+ a limited subset of functions are available with IKEv2
+ (Default AES encryption, authentication based on locally
+ imported X.509 certificates, unencrypted private RSA keys
+ in PKCS#1 file format, limited functionality of the ipsec
+ status command).
