==============================================================================
+------------------------------------------------------------------------------
+--- Functionality changes from Asterisk 18.6.0 to Asterisk 18.7.0 ------------
+------------------------------------------------------------------------------
+
+Channel-agnostic MF support
+------------------
+ * A SendMF application and PlayMF manager
+ application are now included to send
+ arbitrary standard R1 MF tones on the
+ current channel or another specified channel.
+
+app_milliwatt
+------------------
+ * The Milliwatt application's existing behavior is
+ incorrect in that it plays a constant tone, which
+ is not how digital milliwatt test lines actually
+ work.
+
+ An option is added so that a proper milliwatt test
+ tone can be provided, including a 1 second silent
+ interval every 10 seconds. However, for compatability
+ reasons, the default behavior remains unchanged.
+
+app_morsecode
+------------------
+ * Extends the Morsecode application by adding support for
+ American Morse code and adds a configurable option
+ for the frequency used in off intervals.
+
+app_originate
+------------------
+ * Codecs can now be specified for dialplan-originated
+ calls, as with call files and the manager action.
+ By default, only the slin codec is now used, instead
+ of all the slin* codecs.
+
+app_queue
+------------------
+ * Reload behavior in app_queue has been changed so
+ queue and agent stats are not reset during full
+ app_queue module reloads. The queue reset stats
+ CLI command may still be used to reset stats while
+ Asterisk is running.
+
+app_read
+------------------
+ * A new option allows the digit '#' to be read literally,
+ rather than used exclusively as the input terminator
+ character.
+
+app_voicemail
+------------------
+ * Add a new 'S' option to VoiceMail which prevents the instructions
+ (vm-intro) from being played if a busy/unavailable/temporary greeting
+ from the voicemail user is played. This is similar to the existing 's'
+ option except that instructions will still be played if no user
+ greeting is available.
+
+chan_iax2
+------------------
+ * ANI2 (OLI) is now transmitted over IAX2 calls
+ as an information element.
+
+func_env.c
+------------------
+ * Two new functions, DIRNAME and BASENAME, are now
+ included which allow users to obtain the directory
+ or the base filename of any file.
+
+func_framedrop
+------------------
+ * New function to selectively drop specified frames
+ in either direction on a channel.
+
+func_scramble
+------------------
+ * Adds an audio scrambler function that may be used to
+ distort voice audio on a channel as a privacy
+ enhancement.
+
+func_strings
+------------------
+ * A new STRBETWEEN function is now included which
+ allows a substring to be inserted between characters
+ in a string. This is particularly useful for transforming
+ dial strings, such as adding pauses between digits
+ for a string of digits that are sent to another channel.
+
+res_pjproject
+------------------
+ * In pjproject.conf you can now map pjproject log levels
+ to the Asterisk TRACE log level. The default mappings
+ have therefore changed so that only pjproject levels
+ 3 and 4 are mapped to DEBUG and 5 and 6 are now mapped
+ to TRACE. Previously 3, 4, 5, and 6 were all mapped to
+ DEBUG.
+
+res_rtp_asterisk
+------------------
+ * When the address of the STUN server (stunaddr) is a name resolved via DNS, the
+ stunaddr will be recurringly resolved when the DNS answer Time-To-Live (TTL)
+ expires. This allows the STUN server to change its IP address without having to
+ reload the res_rtp_asterisk module.
+
+res_tonedetect
+------------------
+ * Arbitrary tone detection is now available through a
+ WaitForTone application (blocking) and a TONE_DETECT
+ function (non-blocking).
+
+say.c
+------------------
+ * Adds SAYFILES function to retrieve the file names that would
+ be played by corresponding Say applications, such as
+ SayDigits, SayAlpha, etc.
+
+ Additionally adds SayMoney and SayOrdinal applications.
