0.16.0

At a Glance

This is a larger, breaking release with many changes. Most important are the updated configuration options and the graceful shutdown.

Average projects should not require many changes, but reading the upgrade guide and the rest of the release notes is recommended before upgrading.

What's Changed

• The configuration has been updated to require mqtt.host, mqtt.port and provide proper auto completion for all properties. New properties have been added: connect-timeout and mqtt.shutdown.
• Graceful shutdown is now supported and enabled by default. The application now waits for active tasks to complete before shutting down to prevent message loss. This can be disabled with mqtt.shutdown=immediate.
• Functions annotated with MqttSubscribe can now accept any kind and combination of parameters. It is now also possible to receive the raw Mqtt3Publish or Mqtt5Publish (enabling advanced use cases like manual acknowledgment).
• Improved error handling. Errors during message handling are now sent to the MqttMessageErrorHandler which can be implemented by consumers.
• The default ObjectMapper of the application is now used instead of configuring a custom one.
• Various dependency updates and modernizations. The new baseline is Spring Boot 3.2.2.
