Dromara mica-mqtt 2.4.0 Released: Enhanced Server Interfaces, Recommended Upgrade

1. Preface

The official release of Dromara mica-mqtt 2.4.0 is now available. Please note that starting from version 2.4.x, the Maven groupId has been migrated to org.dromara.mica-mqtt, the package name has been switched to org.dromara, and the project has moved to Central Sonatype (snapshots are not supported). All other usage remains consistent with the previous versions. The 2.4.x series will continue to improve and enrich server functionality. Future versions may also introduce some major adjustments and optimizations, though we will strive to minimize interface changes to facilitate upgrades. It is highly recommended to upgrade to the new 2.4.x version as soon as possible.

Additionally, since the old documentation was scattered across various modules and inconvenient to navigate, we have added a new documentation site: https://mica-mqtt.dromara.org
