<description>MQTTnet is a .NET library for MQTT based communication. It provides a MQTT client and a MQTT server (broker).</description>
<releaseNotes>* [Core] Any exception while accessing the underlying data source is now rethrown as "MqttCommunicationException".
* [Core] Extended exception information when an invalid packet type is received.
* [Server] Added TLS 1.2 support (thanks to Zazzmatazz)
* [Client] Added TLS 1.2 support (thanks to Zazzmatazz)</releaseNotes>
* [Server] Added TLS 1.2 support (but not for UWP) (thanks to Zazzmatazz)
* [Client] Added TLS 1.2 support (thanks to Zazzmatazz)
* [Core] Optimized async task management</releaseNotes>
