The HiveMQ team is pleased to announce the availability of HiveMQ 4.28.17.
This maintenance release for the 4.28 series includes the following improvements:
HiveMQ Enterprise MQTT Broker
- Fixed a race condition where subscriptions were not removed for clean-session subscribers who disconnect ungracefully during ongoing subscription updates.
HiveMQ Health API
- Expanded the Diagnostic Archive to include a JSON file of the Health API System Health information.
IMPORTANT: Starting with the next LTS version, Java 21 will be required to run the HiveMQ Platform.
We also recommend using Java 21 to run the current LTS line of the HiveMQ Platform.
If you use the official HiveMQ container images, no action is required – these images have shipped with Java 21 since HiveMQ 4.28.
Have a great day, The HiveMQ Team
