HiveMQ 4.6.4 Maintenance Release

The HiveMQ team is pleased to announce the availability of HiveMQ 4.6.4.

This maintenance release for the 4.6 series includes the following improvements:

• Reduced the memory footprint of client connections by 1 KB per connection.
• Improved observability of extension lifecycle events.
• Improved kafka-to-mqtt message handling during the shutdown of HiveMQ.
• Fixed an issue that could stall a cluster join when an extension with an available consumer is present.
• Resolved an issue where queued messages with large payloads could cause a node to crash.

If you currently use HiveMQ 4.x, we recommend upgrading to version 4.6.4.

Have a great day, The HiveMQ Team
