6.0.0

Breaking Changes

• Added async_ prefix to all async functions to support default completion token. #238, #242
  • Some of async/sync function overload had been conflicted. e.g.) acquire_unique_packet_id().
• Unified naming rule of types to *_type. #232
• Refined type of PacketIdentifier. Now packet_id_type is the type. #231
• Moved include/async_mqtt/broker/.hpp to tool/include/broker/.hpp #224
  • Those are for broker application that is used for system testing.
• Re-organized directory structure with respect to boost libraries. #211, #229, #230, #234
  • It affects the users only if include the specific header file directly.
• Re-designed strand handling. #206
  • Template parameter Strand is removed. Users can pass strand wrapped executor for multi-threading.
  • Associated properties of the completion handler are correctly propagated.
• Removed buffer from packet interface except the interface for advanced user. #195
  • For example, create PUBLISH packet using "topic1", and get the field as string by topic().
    • No allocate_buffer("topic1") is required.
• Organized predefined headers. #194
  • For mqtt, include async_mqtt/all.hpp. In addition,
  • For mqtts, include async_mqtt/predefined_layer/mqtts.hpp
  • For ws, include async_mqtt/predefined_layer/ws.hpp
  • For wss, include async_mqtt/predefined_layer/wss.hpp

Other Updates

• Removed all boost::asio::bind_executor() from the library code. #247, #250
• Client supported flexible parameters. #241, #244
  • You can pass not only packet instance but also the parameters of packet's constructor directly to the packet sending member functions.
• Supported default completion token. #238, #240
• Refined CI. #228
• Refined header dependency checking. #225
• Removed the inclusion of the Boost.Beast detail directory. #223
• Used bound allocator to allocate buffer for packet on receive. #222, #243
• Added convenient handshaking function for underlying layers. #216
  • TCP, TLS, Websocket, Websocket on TLS are handshaked by one function call.
• Refined documents. #220, #222, #232, #233, #234, #235, #243, #252
• Refined examples. #214, #220, #250
