HiveMQ 4.28.11 Maintenance Release

The HiveMQ team is pleased to announce the availability of HiveMQ 4.28.11.

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

HiveMQ Enterprise MQTT Broker

• Fixed an issue that could cause incorrect reporting of free disk space when running HiveMQ in a Kubernetes environment.

HiveMQ Data Hub

• Fixed an issue to ensure Data Hub scripting is correctly disabled when minimum system requirements are not present.

HiveMQ Enterprise Security Extension

• Removed invalid tokens from the debug logging of the JWT authentication manager to increase confidentiality.

IMPORTANT: Java 21 will soon be required to run the HiveMQ Platform.

Since the HiveMQ 4.28 release in April 2024, Java 21 is recommended to run the HiveMQ Platform. For all HiveMQ versions released after April 2025, Java 21 will be required.

If you use the official HiveMQ container images, no action is required because these images have shipped with Java 21 since HiveMQ 4.28. If you do not run HiveMQ as a container, or you build your own container image, we recommend updating to Java 21 before the April 2025 deadline.

Have a great day, The HiveMQ Team
