  • [Core] Added support for MQTTv5 packages.

  • [Client] Added new MQTTv5 features to options builder.

  • [Client] Added uniform API across all supported MQTT versions (BREAKING CHANGE!)

  • [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.

  • [Note] Due to MQTTv5 a lot of new classes were introduced. This required adding new namespaces as well. Most classes are backward compatible but new namespaces must be added.
