I think this statement is not true. While a lot of work was indeed done 
on merging code, there were a lot of new featured added, much more than 
we had we previous major releases, many based on standardizations (e.g., 
presence extensions to conference, dialog info, xcap, a.s.o).

The the core supports processing stun, see ser_stun.{c,h} - the guys at 
ser added that very long time ago.

As for next release, there are lot of features added 
(http://sip-router.org/wiki/features/new-in-devel), more to come, but I 
think most of developers here got tired hunting the ghosts of IETF specs 
that never were any useful nor had a touch with the reality.

As of myself, I really work now on what is demanded, there is no time to 
jump and implement any rfc/draft published based on theories elaborated 
by guys that never implemented their specs. Moreover, some of them are 
now in different boat and make "incredible" statements about sip 
considering their role in the past with this protocol...

Cheers,
Daniel

>   The issue is what of all the new SIP features we need. History-info seems useful for Asterisk, don't know how much it will affect Kamailio. Gruu, well. I haven't seen many implementations out there. I can theoretically see a need for it both in NAT situations and IPv6. Diversion is deprecated. Outbound is the final NAT traversal solution - which seems to be getting a lot of traction. Remember that there was very few participants in this SIPit so 50% is not a "market share" - far from it.
