HiveMQ 4.28.6 Maintenance Release

The HiveMQ team is pleased to announce the availability of HiveMQ 4.28.6.

This maintenance release for the 4.28 series includes the following improvements:

HiveMQ Enterprise MQTT Broker

• Reduced the number of message availability notifications sent to connected clients for shared subscriptions to prevent unnecessary resource usage.
• Refined the audit log statements that actions in the control center generate to provide clearer feedback.

HiveMQ Data Hub

• Added the ability to define an init function in transformation scripts to declare branches proactively.
• Added Arm64 Linux support for Data Hub scripting.
• Fixed an issue with the handling of Control Center policy update ETags to ensure that previously updated policies can be updated/deleted in the Control Center and REST API as expected.
• Adjusted handling of scripts that do not utilize the addPublish functions to enhance performance.

HiveMQ Enterprise Extension for MySQL

• Improved log statements to reduce ambiguity on batch operations that span multiple topics.

HiveMQ Enterprise Extension for PostgreSQL

• Improved log statements to reduce ambiguity on batch operations that span multiple topics.

HiveMQ Platform (general)

• SHA256 checksums are now published for every release artifact on releases.hivemq.com and a .sha256 file ending is appended to each artifact file name.
• The OpenAPI documents for the HiveMQ Enterprise MQTT Broker and HiveMQ Swarm are now published as release artifacts on releases.hivemq.com and are appended with an -openapi.yaml file ending.

Have a great day, The HiveMQ Team
