+* Internal optimization to client code.
+* Small fixes, such as ports in testing and enabling `timeline_test.dart`.
+* When the keep alive manager runs into a timeout, it will finish the transport instead of closing
+  the connection, as defined in the gRPC spec.
 * Update xhr transport to migrate off legacy JS/HTML apis.
 
+## 4.0.1

+* Fix header and trailing not completing if the call is terminated. Fixes [#727](https://github.com/grpc/grpc-dart/issues/727)
+
 ## 4.0.0
 
 * Set compressed flag correctly for grpc-encoding = identity. Fixes [#669](https://github.com/grpc/grpc-dart/issues/669) (https://github.com/grpc/grpc-dart/pull/693)
