Version 0.12.0

Update to Paho C v1.3.12

• Updated to Rust Edition 2021 w/ MSRV 1.63.0
• Upgrade to Paho C v1.3.12
  • Fixes a performance issue, particularily for receiving messages.
  • New URI protocol schemes: "mqtt://" for TCP and "mqtts://" for encrypted SSL/TLS.
• [Breaking] Updated CreateOptions and ConnectOptions behavior:
  • The CreateOptions default is for a "universal" client that can connect using v3.x or v5. (This was previously specified as the v5 option).
    • Can use CreateOptions::new_v3() for a client that can only connect using v3.x
    • Defaults to no message persistence (i.e. persistence is opt-in).
  • The v3.x vs v5 devision is made when connecting.
  • ConnectOptions::new() still defaults to v3.x
  • New constructors for specific protocol version, ConnectOptions::new_v5(), new_ws(), and new_ws_v5(), for v5, websocket, and v5 over websockets, respectively.
  • Connect options default to clean session/state, as appropriate for the constructed protocol version.
  • You select the MQTT protocol version with one of the new constructors, and can not change it after creation. (No longer a set mqtt_version() function).
• AsyncClient::mqtt_version() now returns the version for the current connection - or the most recent successful connection. Removed AsyncClient::current_mqtt_version().
• Updated SubscribeOptions to be more usable.
• Created a new example for MQTT v5 subscriptions with subscribe options.
• #182 Callback must now be Send since they will be called from another thread.
• #172 Linking to User32 library on Windows to try to avoid build problems.
• #170 Updated the cmake crate dependency in -sys to 0.1.49 to support both older CMake (pre v3.12) and newer systems like VS 2022.
• #156 (continued) Added a mutable iterator to TopicMatcher, with functions remove(), get_mut(), and matches_mut()
• #170 Upgraded cmake crate to v0.1.48 to support building with Visual Studio 2022.
• #166 Fix topic matches with single-level wildcard.
• #151 Fixed wrong documentation of QoS 1
• #57 Updated this README with more help for musl builds.
• Fixed clippy warnings

Version 0.9.2

Fixed memory leak in v5 Properties.

• #148 Properly freeing property memory.

Version 0.11.1

Minor fix, particularly to make TopicMatcher more useful.

• #156 Improvements to TopicMatcher:
  • Doesn't require item type to implement Default trait
  • Match iterator returns key/value tuple (not just value).
• #154 Add public interface to retrieve client_id.

Version 0.11.0

• Updated to support Paho C v1.3.10
• New client functions to stop consuming/streaming and to remove callbacks.
• Started a README for the -sys crate.
• Fixed a bunch of lints. Clippy report is clean.
• #152 Consumer won't panic when the receiver drops.
• #113 Build now respects the OPENSSL_STATIC flag (if OPENSSL_DIR or other path flags set).
• #145 impl From<Error> for io::Error An MQTT error can be easily converted back to an I/O error.

Version 0.10.0

• Updated to support Paho C v1.3.9
• Switched consumers/streams to use crossbeam channels and async_channel's, respectively.
• Added a TopicFilter type to match topics against an individual filter (typically containing wildcards).
• Added a TopicMatcher collection to iterate through a set of matching topic filters, such as to match callbacks to specific filters.
• Finally ran rustfmt on source files.
• Fixed MQTT v5 topic alias support.
• #118 Added CreateOptionsBuilder::send_while_disconnected(bool) and detached the behavior somewhat from max_buffered_messages(). Now, setting the buffer size to a non-zero value will not enable off-line buffering.
• #120, #121 Fixed subscribe_many_with_options() outbound opts.
• #122 Some clippy-recommended fixes
• #139 Added a SyncClient struct for repeated publishing to the synchronous client.
• #140 The MQTT protocol version used to create the client is now the default for connecting.
