HiveMQ 4.28.20 Maintenance Release
The HiveMQ team is pleased to announce the availability of HiveMQ 4.28.20.
This maintenance release for the 4.28 series includes the following improvements:
HiveMQ Enterprise MQTT Broker
- HiveMQ Recovery Tool Improvements:
- Fixed incorrect disconnected-since timestamps in client sessions.
- Fixed silent error suppression that could cause incomplete backup file generation.
- Significantly reduced memory consumption for large queue processing.
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
