--- Functionality changes from Asterisk 12 to Asterisk 13 --------------------
------------------------------------------------------------------------------
AMI
------------------
* New DeviceStateChanged and PresenceStateChanged AMI events have been added.
These events are emitted whenever a device state or presence state change
occurs. The events are controlled by res_manager_device_state.so and
res_manager_presence_state.so. If the high frequency of these events is
problematic for you, do not load these modules.

--- Functionality changes from Asterisk 12.2.0 to Asterisk 12.3.0 ------------
