     <releaseNotes>
 * [Client] Fixed wrong value for "ClientWasConnected" in "MqttClientDisconnectedEventArgs" #976 (thanks to @dbeinder).
 * [Client] Added direct support for Amazon AWS connections (requires .NET Core 3.1) (thanks to @henning-krause).
+* [ManagedClient] Exposed the internal MQTT client.
 * [Server] Added client message queue interceptor for QoS level (tahnks to @msallin).
