# HiveMQ 4.28.32 Maintenance Release

The HiveMQ team is pleased to announce the availability of **HiveMQ 4.28.32**.

This maintenance release for the 4.28 series includes the following bug fixes and improvements:

## HiveMQ Enterprise MQTT Broker

- Updated the default `logback.xml` file to write event logs asynchronously to avoid reduced broker performance when many clients connect and disconnect frequently. If you customized your `conf/logback.xml` file, add the new asynchronous event log configuration manually during the upgrade.
- Fixed an issue where a cluster could stop accepting new or rejoining nodes if a node left the cluster during a join operation or if data replication failed.
- Fixed an issue where a malformed CONNECT packet could abort active trace recordings.
- Fixed an issue where, under TCP backpressure, the broker could send MQTT packets such as PINGRESP after it sent a `DISCONNECT` packet for a keep-alive timeout.
- Fixed an issue where extension consumers with overlapping topic filters could receive duplicate messages, which affected the Kafka, MongoDB, MySQL, PostgreSQL, Microsoft SQL Server, Data Lake, Snowflake, and Bridge extensions.

## HiveMQ Enterprise Security Extension

- Fixed an issue where a MySQL realm that uses MySQL Connector/J could not connect over TLS when its configuration listed more than one TLS protocol or cipher suite.

## HiveMQ Enterprise Extension for Kafka

- Fixed intermittent load failures of custom transformers with multiple constructors in the Kafka extension by always using the public no-argument constructor.
