+- The nua module now has support for NAT traversal using SIP outbound. 
+  Because rather limited support for SIP outbound by SIP proxies (nada), a
+  rport-based NAT traversal was also added. There is also a registration
+  probe and registation keepalive using OPTIONS request. The NAT traversal
+  can be disabled by either giving the Contact header explicitly to the
+  nua_register() call or by setting NUTAG_OUTBOUND() option to NULL. 
+
+- The nua module now supports GRUU, too. The GRUU is a special Contact URI,
+  which is generated by the registrar/home proxy. The requests sent to the
+  GRUU Contact URI are routed through the registrar/home proxy towards the
+  user agent. An User-Agent wanting to use GRUU needs to enable it. It has
+  to generate an unique instance identifier (for instance, by calling
+  nua_generate_instance_identifier()), store the identifier to permanent
+  storage (config file) and always include the same identifier in
+  NUTAG_INSTANCE() when calling nua_create(). Stack generates GRUU when it
+  receives a "gruu" parameter in an response to REGISTER request, and uses
+  the GRUU as Contact in INVITE, UPDATE, SUBSCRIBE and NOTIFY transactions.
+
 - DNS server discovery support added for win32. Sofia-SIP is now able
   to get a list of configured nameservers from the Windows
   registry database (similar to /etc/resolv.conf on UNIX systems). Closes
