Async.MQTT5 Files

Version 1.0.3 is the final release of Async.MQTT5. Future versions will be released under the Boost.MQTT5 name, with the boost::mqtt5 namespace and corresponding include paths. The async_mqtt5 namespace and paths will no longer be used in subsequent releases.

This version includes the following changes:

General changes

• Added Clang 16-18, address, and UB sanitiser builds to CI

Library changes

• The mqtt_client can now establish IPv6 connections with Brokers.
• Boost.Beast is an optional dependency and is only required when the Client establishes a connection over WebSocket.
  • When using WebSocket connections, users must now explicitly include async_mqtt5/websocket.hpp.
• Lifted the requirement that all mqtt_client::async_xxxcompletion handlers must be bound to the same executor.
• Removed thread mutex from async_mutex.
• Reworked examples to accept command line parameters.
• Added logging support. The mqtt_client now accepts a third template argument, LoggerType, that can be used to log events within the Client (such as connection failures and disconnections).
  • A basic logger, logger is provided as a LoggerType implementation that logs messages to the stderr.

Documentation changes

• Implemented documentation changes regarding README.md and the Getting Started chapter.
