-Subject: [PATCH] evsub:  Add pjsip_evsub_set_uas_timeout.
-
-A UAS which needs to recreate incoming subscriptions from a persistent
-store can call pjsip_dlg_create_uas_and_inc_lock and
-pjsip_evsub_create_uas as long as they've persisted the
-correct data but since the timer is triggered by an incoming subscribe,
-it's never set and the subscription never expires.
-
-* Add pjsip_evsub_set_uas_timeout which is just a wrapper around
-  evsub.c:set_timeout(sub, TIMER_TYPE_UAS_TIMEOUT, seconds)
-
-* Also, fixed copy-paste error in pjsip_sub_state_hdr_print when
-  printing retry-after parameter.

-Subject: [PATCH 3/5] r5559 svn backport Fix to resolve DNS SRV crashes.
-
-Re #1994 (misc): Don't try to resolve a DNS SRV query that is already considered resolved.
-Thanks to Richard Mudgett for the patch.
-
-srv_resolver.c: Don't try to send query if already considered resolved.
-
-* In resolve_hostnames() don't try to resolve a query that is already
-considered resolved.
-
-* In resolve_hostnames() fix DNS typo in comments.
-
-* In build_server_entries() move a common expression assigning to cnt
-earlier.
-
-sip_transport.c: Fix tdata object name to actually contain the pointer.
-
-It helps if the logs referencing a tdata object buffer actually have
-a name that includes the correct pointer as part of the name.  Also
-since the tdata has its own pool it helps if any logs referencing the
-pool have the same name as the tdata object.  This change brings tdata
-logging in line with how tsx objects are named.

-Subject: [PATCH] Add support for registering IPv6 transport type.
-
-This change allows an IPv6 transport type to be registered
-and used. The IPv4 transport is found (if available) and the
-IPv4 flag added to its type to match how the finding of
-IPv6 transport types works.

-Subject: [PATCH] Set PJSIP_INV_SUPPORT_UPDATE correctly in
- pjsip_inv_verify_request3
-
-pjsip_inv_verify_request3 was setting rem_options when UPDATE was
-detected in the Allow header.  That's just an internal variable and
-doesn't go anywhere.  It's '*options' that needs to be set.
