 # Frequenz Dispatch Client Library Release Notes
 
+## Features
+
+* `Dispatch.end_time` has been added to the `Dispatch` class, which is the time when the dispatch ended as calculated by the server. `dispatch-cli` will also print this time.
+
 ## Bug Fixes
 
-* Fix that duration=0 was sent & received as None.
 * Fix that `dispatch-cli stream` would try to print an event as dispatch, causing an exception.
