HiveMQ 4.5.2 Maintenance Release

The HiveMQ team is pleased to announce the availability of HiveMQ 4.5.2.

This maintenance release for the 4.5 series includes the following improvements:

• Improved memory and CPU usage for all types of MQTT messages.
• Optimized message throughput for subscribers with high publication rates.
• Numerous small improvements that enhance overall performance.
• Improved message throughput stability for shared subscriptions.
• Adjusted handling of the temporary CPU usage increase that replication causes when a node leaves the cluster for better distribution across the remaining nodes.
• Reduced memory usage during replication when a node leaves or joins a cluster.

If you currently use HiveMQ 4.x, we recommend upgrading to version 4.5.2.

Have a great day, The HiveMQ Team
