v2.5.15 (Aug 14, 2007)
   change ipsec_breakroute to permit non-existant eroute's to be replaced.  
   fix for NAT-T negotiation with IP address changes during negotiation.
   adjusted addconn to support nat-t debug keywords.

v2.5.14 (Jul 19, 2007)
   failed attempt to fix ipsec_breakroute.
   fixed leftsendcert= to be implemented in keyword parser.
   introduced startnetkey functions.
   UML kernel configuration canonicalization updated.

v2.5.13 (May 7, 2007)
   move DNS lookups from libipsecconf into pluto, where they belong. DNS lookups
	are still only done once during conn load time, and are done synchronously.

v2.5.12 (Apr 30, 2007)
   A fix to detect that XEN has been patched into the kernel, and set
   some of the 2.6.18 changes.
   never log starter_log() things to stdout, they always go to stderr.
   when a packet is passed through, do not call NF_IP_LOCAL_OUT, as it has already 
	passed through the output hooks, and doing it again, confuses things
	causing ip_route_me_harder() which creates a look, since it does the flow
	lookup again. (This doesn't happen if the kernel hasn't got XFRM support)
   fixed parsing of config file so that "version 2" is accepted.
   fixed addconn to respect "right/left"sourceip=, new test case sourceip-01 
   fixed processing of "first"/"last" packet for %trap/%hold conns in KLIPS, it now
	properly forwards the packets when the packet is released.
   

v2.5.11 (Apr 19, 2007)
   Some fixes in KLIPS for "ipsec eroute --clear" bug. It is not clear
   why this suddendly became an issue, or if it would have been an issue
   previously, given the right compiler optimization.
   
v2.5.10 (Apr 2, 2007)
   Includes fixes for xmlto generation for _confread directory.

v2.5.09 (Apr 2, 2007)
   Minor fix to build process, updated CHANGES file.
 
v2.5.08 (Apr 2, 2007)
   Correct release.
   Includes some changes to permit OE to work without nexthop,
   however this seems to cause it to return an unreachable on 
   the first message.

v2.5.07	-dud due to release script error.

v2.5.06 (?)
   set LANGUAGE, LANG and LC_ALL in setup script.
   change OE off by default note and scripts.
   Merge of additional code from 2.4.
   
v2.5.05 (Feb 14, 2007)
   2.5.03 and 2.5.04 were not properly released, and 2.5.05 now
   is properly released and includes below items
    
v2.5.04 (?)
    zero peer_ca to avoid crashes.
    (include glob's may still not work correctly)

v2.5.0sbs5 (Dec 12, 2005)
    fixed issues with libwhack not getting built with VIRTUAL_IP.
    adjusted programs/pluto/Makefile to depend upon libraries better

v2.5.0sbs4 (Dec 11, 2005)
    When a template conn is instantiated for a phase 1 configuration, it
	may still need to be adjusted to a virtual IP address. In addition,
	change the order of the virtual IP address setting and the
	port-wildcard processing.
        This patch also provides some additional debugging of the proposal
	which actually processed by the machinery.

    tests for L2TP+X.509 L2TP configuration --- 2 clients behind the
        same NAT with certificates that need to have their connection both
        instantiated (in phase 1) and virtualized (in phase 2).

v2.5.03 (Jan 10, 2007)

    ipsec.conf parsing should ignore keywords that start with x-
	they are a form of structured comment.
    added in forceencaps= keyword.
    process wildcards with glob() in include statements.

v2.5.02 (?)
    fixed bug in ipsec.conf parser, where it could not read values
       that had = in them (such as base64 encoded keys)
    fixed bug in key continuation code that could cause a crash
	if the DNS request timed out after the state was deleted
	for other reasons.
 
v2.5.01 (Jan 2, 2007)
    merged xauthusername code base + multinet tests in.
    removed /dev/hw_random from list of valid random sources on linux.
        use "rngd" instead to feed /dev/random.

v2.5.00 (Nov 2, 2006)
    fixed various bugs with lifetime values in ipsec.conf parser
    AES-128 (group 5, MD5 or SHA1 for PRF) is now accepted for phase 1,
	and it is now the preferred cipher as well. This should be the
	case for Main mode, Aggressive mode, and for XAUTH client and
	XAUTH server, and PSK and RSA sig mode.

    fixes so that starter will now compile
    move whacklib to lib/libwhack
    adjust makefiles to work with OBJDIR version of Makefile.program
    switch to OBJDIR in programs/* and lib/* if it is defined

    added sanitizer for PID files
    be smarter about including git version info into version
    We need to use /dev/urandom first, as it has more random than /dev/random.
       Otherwise, we run out really fast (within a few minutes)
    Use endian.h when comiling out-of-kernel
    patch to turn error about 17/500,0/0 vs 17/0 error with Cisco VPN3000
       into a warning.
    remove test for NAT-T VID vs NATD payload test. It fails for reasons
       that are unknown at this time, and this check is really being pedantic.
    MAJOR: use starter code for "addconn"
    MAJOR: always use OBJDIRs, and compile on Windows (no kernel)
    MAJOR: includes "Taproom" code --- TCL call outs from pluto at IKE
		transition states.

* Fix for sock.sk_stamp type change in 2.6.22 [dhr]
