* [Core] Added support for MQTTv5 packages.
* [Core] Performance improvements.
* [Core] Removed obsolete methods.
* [Core] Fixed a memory leak when processing lots of messages (thanks to @tschanko)
* [Core] Added more overloads for MQTT factory.
* [Core] The client password is now hidden from the logs (replaced with **** if set).
* [Core] Fixed a memory leak when using SSL connections (thanks to @biovoid).
* [Client] Added validation of topics before publishing.
* [Client] Added new MQTTv5 features to options builder.
* [Client] Added uniform API across all supported MQTT versions (BREAKING CHANGE!)
* [Client] The client will now avoid sending an ACK if an exception has been thrown in message handler (thanks to @ramonsmits).
* [Client] Fixed issues in QoS 2 handling which leads to message loss.
* [Client] Replaced all events with proper async compatible handlers (BREAKING CHANGE!).
* [Client] Added more configuration values to TCP endpoint options.
* [ManagedClient] Replaced all events with proper async compatible handlers (BREAKING CHANGE!).
* [ManagedClient] The log ID is now propagated to the internal client (thanks to @vbBerni).
* [ManagedClient] Added validation of topics before publishing.
* [ManagedClient] The internal MQTT client is now closed properly (thanks to @vbBerni).
* [Server] Added support for MQTTv5 clients. The server will still return _success_ for all cases at the moment even if more granular codes are available.
* [Server] Fixed issues in QoS 2 handling which leads to message loss.
* [Server] Replaced all events with proper async compatible handlers (BREAKING CHANGE!).
* [Server] The used logger instance is now propagated to the WebSocket server adapter.
