MQTTnet 3.0.9
MQTTnet is a high performance .NET library for MQTT based communication. It provides a MQTT client and a MQTT server (broker) and supports v3.1.0, v3.1.1 and v5.0.0 of the MQTT protocol.
No packages depend on MQTTnet.
* [All] Due to a merge issue not all changes are included in 3.0.8. All these changes are now included in this version.

* [ManagedClient] Added builder class for MqttClientUnsubscribeOptions (thanks to @dominikviererbe).
* [ManagedClient] Added support for persisted sessions (thansk to @PMExtra).
