8.0.0

Breaking Changes

• client becomes shared_ptr similar to endpoint. #315
  • To create client instance, use client<...>::create(args) similar to endpoint.
  • This is required to ensure the client's lifetime during async operation is maintained.
  • client and endpoint now have a consistent interface.

Other Updates

• Moved endpoint definition (using) to endpoint_fwd.hpp. #311, #312
• Install *.ipp files along with other header files. #309
• Refined documents. #308

7.0.0

Breaking Changes

• client::async_recv() CompletionHandler signature is updated to void(error_code, packet_variant). #281
  • packet_variant has one of std::monostate, [v3_1_1|v5]::publish_packet, [v3_1_1|v5]::disconnect_packet, or v5::auth_packet.
• Renamed the typename from pubres_t to pubres_type for consistency. #280
• Re-designed error_code handling to align with Boost.Asio's approach. #266, #270, #271, #272, #273, #299
  • All async functions have the Completion Handler signature as void(async_mqtt::error_code, ...), except void().
    • This ensures compatibility with other Boost.Asio based libraries, and Boost.Asio itself.

Other Updates

• Added footprint example. #304
• Added async_auth() to client. #303
• Added reconnect code to examples. #302
• Fixed dangling reference on underlying_handshake. #301

• Fixed non-existent topic alias treatment. #289
• Fixed connack packet sending condition on error. #288
• Fixed async_recv after cancel behaving invalidly. #287
• Fixed cancel treatment. #286
• Added using recycling allocator option for the broker. #283
• Added separate compilation mode support. #282
  • To enable separate compilation mode, define ASYNC_MQTT_SEPARATE_COMPILATION.
• Added bind_cancellation_slot test. #268
• Supported PINGREQ overriding by ServerKeepAlive. #271
• Refined tests. #269, #274, #275, #287, #288, #289, #290, #296, #297
• Refined documents. #276, #292, #305, #306, #307

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 the inclusion of the Boost.Beast detail directory. #223
• Used bound allocator to allocate buffer for packet on receive. #222, #243
