HiveMQ 4.28.14 Maintenance Release

The HiveMQ team is pleased to announce the availability of HiveMQ 4.28.14.

This maintenance release for the 4.28 series includes the following improvements:

HiveMQ Enterprise MQTT Broker

• Fixed an issue with batched subscription and unsubscription requests to ensure consistent ordering.

HiveMQ Health API

• Improved error reporting in the Health API to include extension startup, shutdown, and runtime failures.

HiveMQ REST API

• Fixed an issue with Trace Recording startAt and endAt timestamps to ensure that millisecond precision is retained.

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
