HiveMQ 4.3.8 Maintenance Release
The HiveMQ team is pleased to announce the availability of HiveMQ 4.3.8.
This maintenance release for the 4.3 series includes the following improvements:
- Corrected an issue that could infrequently prevent new nodes from joining a cluster
- Improved destination checks in an upstream library to ensure rolling upgrade stability
- Improved heartbeat configuration for faster failure detection
- Improved cluster merging and automatic healing capabilities for better cluster stability
- Numerous performance enhancements for cluster operations such as replication
- Reduced the amount of CPU usage and traffic that client disconnection generates when a node in a HiveMQ cluster stops
- Corrected an issue that could disrupt message flow under some circumstances
- Fine-tuned the dns-4.3.8 Docker image for accurate configuration of the cluster transport type
- Fixed an issue where the Prometheus extension did not return metrics under load
- Corrected format error in the heap-dump path to ensure that a heap dump is automatically generated when HiveMQ runs out of memory
- Adjusted the way that license files are read to the license folder to increase verification accuracy
- Fixed a rare NullPointerException that could appear during the license check of a cluster
If you currently use HiveMQ 4.3.x, we recommend upgrading to version 4.3.8.
Have a great day, The HiveMQ Team
