Changes since 0.6.3:

0.6.6
	* src/racoon/isakmp_xauth.c: Build fix
	* src/racoon/pfkey.c: Sets NAT-T ports to 0 if no NAT
	  encapsulation in pk_sendgetspi().
	* src/racoon/pfkey.c: Sets NAT-T ports to 0 if no NAT
	  encapsulation in pk_sendupdate().
	* src/racoon/isakmp_xauth.c: fix memory leak
	* src/racoon/{cfparse.y|handler.h}: typos

0.6.5
	* src/racoon/isakmp.c: Fixed zombie PH1 handler when isakmp_send()
	  fails in isakmp_ph1resend()
	* src/racoon/{cfparse.y|ipsec_doi.c}: Temporary fix for /32
	  subnets parsing.
	* src/racoon/isakmp_cfg.c: make software behave as the documentation
	  advertise for INTERNAL_NETMASK4. Keep the old INTERNAL_MASK4 to
	  avoid breaking backward compatibility.
	* src/racoon/session.c: Fixed / cleaned up signal handling.

0.6.4
	* configure.ac src/racoon/plog.c: backported Fred's workaround for
	  %zu problems on (at least) FreeBSD4.
	* src/racoon/session.c: backport: fix possible race conditions in
	  signal handlers (see session.c 1.17).
	* src/libipsec/pfkey_dump.c: fixed compilation when NAT_T
	  disabled (Fred has still some CVS problems).
	* src/libipsec/{libpfkey.h|pfkey_dump.c}: add a sadump_withports
	  function to display SAD entries with their associated ports.
	* src/setkey/{parse.y|setkey.c|setkey.8}: allow to use setkey -p flag
	  in conjunction with -D to show SADs with the port, allow both get and
	  delete commands to use bracketed ports if needed.
	* src/racoon/racoon.conf.5: Style changes
