PJSIP supports RTCP-XR?

 Hi,

 I want to using PJLIB-RTCP-XR in my program and I've read about "PJSIP 
 0.9.0 supports RTCP-XR" 
 (http://lists.pjsip.org/pipermail/pjsip_lists.pjsip.org/2008-July/003517.html), 
 there was 3 years ago. Is there any new implementation/development in 
 this funktion?

 Thank you so much,
 widya saseno
