+
+        F_MALLOC: Optimize the free() operation
+
+        Commit bdaaf60b2c introduced a side-effect of gradually moving the
+        fragment "action" towards the exponential, non-optimized hash table
+        buckets (i.e. buckets 2049 ... 2100).  Here, the fragments were inserted
+        in a sorted fashion, with the sorted-insert algorithm costing a O(N)
+        iteration on each free operation instead of a simple O(1).
+
+        Consequently, the user experience of this effect is that "dr_reload"
+        operations were stalling for 12 minutes (coming up from 24 seconds!),
+        when working with large rule sets (millions of rules).  Interestingly
+        enough, the stalling was not due to the caching phase -- malloc() --
+        rather due to the cleanup phase, when clearing the old rules -- free()!
+
+        To address this issue:
+
+        * we drop the sorted insertion completely for buckets 2049 ... 2100, and
+            simply do a list prepend operation: O(1), as with the others
+        * we make all allocation requests from these buckets return the next
+           bucket (!!), thus guarantee'ing our requested fragment.  Examples:
+
+              malloc(18K) -> now you always get a 32K+ frag, but instantly!
+              malloc(37K) -> now you always get a 64K+ frag, but instantly!
+        * this does not make F_MALLOC more wasteful, since the extra frag
+          space gets split anyway into a new fragment, with the two eventually
+          coalescing together again thanks to commit bdaaf60b2c
+
+        (cherry picked from commit e6b4de51298eb78aef097cbfd1c34ada17b9b78f)

+        * [c64766a85] :
+
+        [uac_registrant] fix passing wrong context to authenticated REGISTER
+
+        When sending the authenticating REGISTER, be sure a new context is provided. This will avoid the usage of the context belonging to the first (challenged) REGISTER. This mixup of the context was breaking the tracing of these REGISTER requests via local route.

+        tls: remove from map when destroying

+        This prevents a crash that was generated at runtime due to the fact that

+        * [279b2114a] :
+
+        [call_center] fix overflowing the per-agent array of skills
+
+        As the array of skills is pre-allocated inside the agent struct, be sure you do not overflow it when populating the agent's skills (from DB).
+        Also, the logstate/logged_in value for an agent is read from DB or MI and it must be forced to 0/1 values, as it is later used as index. Yet another overflow fixed here.

+        * [10d53b312] :
+
+        [acc] removed old workaround multiple int2str() in acc_extra
+
+        Since 2.3 we actually do not need this, as each acc_extra is individually set into its own buffer.

+        Related to 0ff82562bd74a177184b1e179c3a607446c47b78
+        We need to review this logic (of static_detector) as it looks to be broken as it is now.
