HiveMQ 4.9.7 Maintenance Release

The HiveMQ team is pleased to announce the availability of HiveMQ 4.9.7.

This maintenance release for the 4.9 series includes the following improvements:

HiveMQ Enterprise MQTT Broker

• Streamlined the collection of subscribers to achieve a more efficient distribution of the publish workload to all responsible nodes of a cluster.
• Fixed an issue that could negatively impact performance when the client event history feature is in use.
• Added metrics to provide increased observability for tasks that trigger changes in the overload protection levels.
• Improved the way that system metrics are handled to provide increased granularity.
• Increased feedback in overload protection log file statements to improve observability.

HiveMQ Enterprise Distributed Tracing Extension

• Updated span attribute names in the HiveMQ Distributed Tracing Extension to support new OpenTelemetry semantic conventions.

Have a great day, The HiveMQ Team
