 ## 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.
+* `stream()` takes a new parameter `stream_retry_strategy` which allows to configure the retry strategy for the stream. The default is `LinearBackoff` with 1 second interval and no limit.
+
+## Upgrading
+
+* `stream()` now returns a `GrpcStreamBroadcaster` instead of a `Receiver`. This is a breaking change, existing code can be upgraded by simply appending `.new_receiver()`.
+
 
 ## 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.
