The HiveMQ team is pleased to announce the availability of HiveMQ 3.3.2. This is a maintenance release for the 3.3 series and brings the following improvements:

• The Web UI now shows the maximum offline queue size and strategy for clients
• Improved unsubscribe performance
• The Web UI now shows a warning if different HiveMQ versions are in a cluster
• At Startup HiveMQ shows the enabled cipher suites and protocols for TLS listeners in the log
• The Web UI Dashboard now shows MQTT Publishes instead of all MQTT messages in the graphs
• Updated integrated native SSL/TLS library to latest version
• Improved message ordering while the cluster topology changes
• Fixed a cosmetic NullPointerException with background cleanup jobs
• Fixed an issue where Web UI Popups could not be closed on IE/Edge and Safari
• Fixed an issue which could lead to an IllegalArgumentException with a QoS 0 message in a rare edge-case
• Improved persistence migrations for updating single HiveMQ deployments
• Fixed a reference counting issue
• Fixed an issue with rolling upgrades if the AsyncMetricService is used while the update is in progress

You can download the new HiveMQ version here.

We recommend to upgrade if you are an HiveMQ 3.3.x user.
