HiveMQ Enterprise MQTT Broker

Fixed an issue with single writer task execution that could cause the broker to crash during shutdown.

Fixed a rare issue that could cause the broker to crash during a shutdown.

Fixed an issue where the Diagnostic Archive could log an incorrect count of exported client sessions and shared subscriptions.

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.
