+--- Functionality changes from Asterisk 16.0 to Asterisk 16.6.0-rc2 ----------
+------------------------------------------------------------------------------
+
+Core
+------------------
+ * H.265/HEVC is now a supported video codec and it can be used by
+   specifying "h265" in the allow line.
+   Please note however, that handling of the additional SDP parameters
+   described in RFC 7798 section 7.2 is not yet supported.
+
+func_jitterbuffer
+------------------
+ * The JITTERBUFFER dialplan function now has an option to enable video synchronization
+   support. When enabled and used with a compatible channel driver (chan_sip, chan_pjsip)
+   the video is buffered according to the size of the audio jitterbuffer and is
+   synchronized to the audio.
+
+taskprocessor.c
+------------------
+ * Added two new CLI commands to reset stats for taskprocessors. You can
+   reset stats for a single, specific taskprocessor ('core reset
+   taskprocessor <taskprocessor>'), or you can reset all taskprocessors
+   ('core reset taskprocessors'). These commands will reset the counter for
+   the number of tasks processed as well as the max queue size.
