+Summary:
+----------------------------------------
+
+- apply_patches: Use globbing instead of file/sort.
+- apply_patches: Sort patch list before applying
+- pjsip: Upgrade bundled version to pjproject 2.13.1
+
+User Notes:
+----------------------------------------
+
+- ### res_http_media_cache: Introduce options and customize
+ The res_http_media_cache module now attempts to load
+ configuration from the res_http_media_cache.conf file.
+ The following options were added:
+ * timeout_secs
+ * user_agent
+ * follow_location
+ * max_redirects
+ * protocols
+ * redirect_protocols
+ * dns_cache_timeout_secs
+
+- ### format_sln: add .slin as supported file extension
+ format_sln now recognizes '.slin' as a valid
+ file extension in addition to the existing
+ '.sln' and '.raw'.
+
+- ### bridge_builtin_features: add beep via touch variable
+ Add optional touch variable : TOUCH_MIXMONITOR_BEEP(interval)
+ Setting TOUCH_MIXMONITOR_BEEP/TOUCH_MONITOR_BEEP to a valid
+ interval in seconds will result in a periodic beep being
+ played to the monitored channel upon MixMontior/Monitor
+ feature start.
+ If an interval less than 5 seconds is specified, the interval
+ will default to 5 seconds. If the value is set to an invalid
+ interval, the default of 15 seconds will be used.
+
+- ### app_senddtmf: Add SendFlash AMI action.
+ The SendFlash AMI action now allows sending
+ a hook flash event on a channel.
+
+- ### res_mixmonitor: MixMonitorMute by MixMonitor ID
+ It is now possible to specify the MixMonitorID when calling
+ the manager action: MixMonitorMute. This will allow an
+ individual MixMonitor instance to be muted via ID.
+ The MixMonitorID can be stored as a channel variable using
+ the 'i' MixMonitor option and is returned upon creation if
+ this option is used.
+ As part of this change, if no MixMonitorID is specified in
+ the manager action MixMonitorMute, Asterisk will set the mute
+ flag on all MixMonitor audiohooks on the channel. Previous
+ behavior would set the flag on the first MixMonitor audiohook
+ found.
+
+- ### pbx_dundi: Add PJSIP support.
+ DUNDi now supports chan_pjsip. Outgoing calls using
+ PJSIP require the pjsip_outgoing_endpoint option
+ to be set in dundi.conf.
+
+- ### test.c: Fix counting of tests and add 2 new tests
+ The "tests" attribute of the "testsuite" element in the
+ output XML now reflects only the tests actually requested
+ to be executed instead of all the tests registered.
+ The "failures" attribute was added to the "testsuite"
+ element.
+ Also added two new unit tests that just pass and fail
+ to be used for testing CI itself.
+
+- ### cli: increase channel column width
+ This change increases the display width on 'core show channels'
+ amd 'core show channels verbose'
+ For 'core show channels', the Channel name field is increased to
+ 64 characters and the Location name field is increased to 32
+ characters.
+ For 'core show channels verbose', the Channel name field is
+ increased to 80 characters, the Context is increased to 24
+ characters and the Extension is increased to 24 characters.

+Detail:
+----------------------------------------
+
+- ### apply_patches: Use globbing instead of file/sort.
+ Author: Sean Bright
+ Date: 2023-07-06
+
+ This accomplishes the same thing as a `find ... | sort` but with the
+ added benefit of clarity and avoiding a call to a subshell.
+
+ Additionally drop the -s option from call to patch as it is not POSIX.
+
+- ### apply_patches: Sort patch list before applying
+ Author: George Joseph
+ Date: 2023-07-06
+
+ The apply_patches script wasn't sorting the list of patches in
+ the "patches" directory before applying them. This left the list
+ in an indeterminate order. In most cases, the list is actually
+ sorted but rarely, they can be out of order and cause dependent
+ patches to fail to apply.
+
+ We now sort the list but the "sort" program wasn't in the
+ configure scripts so we needed to add that and regenerate
+ the scripts as well.
+
+ Resolves: #193
