+------------------------------------------------------------------------------
+
+Messaging
+------------------
+ * In order to reduce the amount of AMI and ARI events generated,
+   the global "Message/ast_msg_queue" channel can be set to suppress
+   it's normal channel housekeeping events such as "Newexten",
+   "VarSet", etc. This can greatly reduce load on the manager
+   and ARI applications when the Digium Phone Module for Asterisk
+   is in use.  To enable, set "hide_messaging_ami_events" in
+   asterisk.conf to "yes"  In Asterisk versions <18, the default
+   is "no" preserving existing behavior.  Beginning with
+   Asterisk 18, the option will default to "yes".
+
+app_mixmonitor
+------------------
+ * If the 'filename' argument to MixMonitor() ended with '.wav49,'
+   Asterisk would silently convert the extension to '.WAV' when opening
+   the file for writing. This caused the MIXMONITOR_FILENAME variable to
+   reference the wrong file. The MIXMONITOR_FILENAME variable will now
+   reflect the name of the file that Asterisk actually used instead of
+   the filename that was passed to the application.

+------------------
+ * The "TextMessageReceived" event used to include a list of "TextMessageVariable"
+   objects as part of its output. Due to a couple of bugs in Asterisk a list of
+   received variables was never included even if ones were available. However,
+   variables set to send would be (which they should have not been), but would
+   fail validation due to the bad formatting.
+
+   So basically there was no way to get a "TextMessageReceived" event with
+   variables. Due to this the API has changed. The "TextMessageVariable" object
+   no longer exists. "TextMessageReceived" now returns a JSON object of key/value
+   pairs. So for instance instead of a list of "TextMessageVariable" objects:
+
+   [ TextMessageVariable, TextMessageVariable, TextMessageVariable]
+
+   where a TextMessageVariable was supposed to be:
+
+   { "key": "<var name>", "value":, "<var value>" }
+
+   The output is now just:
+
+   { "<var name>": "<var value>" }
+
+   This aligns more with how variables are specified when sending a message, as
+   well as other variable lists in ARI.
