 ===========================================================
 
 New in 15.0.0:
 
-Core:
- - The 'Data Retrieval API' has been removed. This API was not actively
-   maintained, was not added to new modules (such as res_pjsip), and there
-   exist better alternatives to acquire the same information, such as the
-   ARI. As a result, the 'DataGet' AMI action as well as the 'data get'
-   CLI command have been removed.
-
 Build System:
  - '--with-pjproject-bundled' is now the default when running ./configure
    It can be disabled with '--without-pjproject-bundled'.
 
-From 14.6.0 to 14.7.0:
-
-Core:
- - ast_app_parse_timelen now returns an error if it encounters extra characters
-   at the end of the string to be parsed.
-
-From 14.4.0 to 14.5.0:
-
 Core:
- - Support for embedded modules has been removed.  This has not worked in
-   many years.  LOADABLE_MODULES menuselect option is also removed as
-   loadable module support is now always enabled.
-
-From 14.3.0 to 14.4.0:
-
-res_rtp_asterisk:
- - The RTP layer of Asterisk now has support for RFC 5761: "Multiplexing RTP
-   Data and Control Packets on a Single Port." For the PJSIP channel driver,
-   chan_pjsip, you can set "rtcp_mux = yes" on a PJSIP endpoint in pjsip.conf
-   to enable the feature. For chan_sip you can set "rtcp_mux = yes" either
-   globally or on a per-peer basis in sip.conf.

-New in 14.0.0
-
-ARI:
- - The policy for when to send "Dial" events has changed. Previously, "Dial"
-   events were sent on the calling channel's topic. However, starting in Asterisk
-   14, if there is no calling channel on which to send the event, the event is
-   instead sent on the called channel's topic. Note that for the ARI channels
-   resource's dial operation, this means that the "Dial" events will always be
-   sent on the called channel's topic.
-
-Queue:
- - When reloading the members of a queue, the members added dynamically (i.e.
-   added via the CLI command "queue add" or the AMI action "QueueAdd") now have
-   their ringinuse value updated to the value of the queue. Previously, the
-   ringinuse value for dynamic members was not updated on reload.
-
-Queue log:
- - New RINGCANCELED event is logged when the caller hangs up while ringing.
-   The data1 field contains number of miliseconds since start of ringing.
-
-Channel Drivers:
-
-chan_dahdi:
- - Support for specifying a DAHDI channel using a path under /dev/dahdi
-   ("by name") has been removed. It was never used. Instead you should
-   use kernel-level channel number allocation using span assignments.
-   See the documentation of dahdi-linux and dahdi-tools.
+ - Multi-stream support has been added so a channel can have multiple
+   streams of the same type such as audio and video.
 
+ - The 'Data Retrieval API' has been removed. This API was not actively
+   maintained, was not added to new modules (such as res_pjsip), and there
+   exist better alternatives to acquire the same information, such as the
+   ARI. As a result, the 'DataGet' AMI action as well as the 'data get'
+   CLI command have been removed.
