 ## 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.
+* The dispatch client now supports the official dispatch domain: `grpc://dispatch.eu-1.staging.api.frequenz.com:443`
 
 ## Upgrading
 
 * Renamed `Client` class to `DispatchApiClient` for clarity.
-
-## Bug Fixes
-
-* Fix that `dispatch-cli stream` would try to print an event as dispatch, causing an exception.
-* Fix that `stream()` would not reconnect and just closes the channel upon disconnection.
