The HiveMQ team is pleased to announce the availability of HiveMQ MQTT Client 1.2.2.

This patch release for version 1.2 includes the following improvements:

🐞 Bug fixes

  • Fixed that a failure to shutdown the netty event loop leaves bad executor in cache
  • Fixed that threads are not terminated when using manual acknowledgement with QoS 0
  • The client always reads the DISCONNECT message even if the server closes the connection while the client sends data
  • SSLExceptions and ProxyConnectExceptions are not logged unnecessarily when they are handled correctly

🗒️ Miscellaneous

  • Direct publishing to Maven Central
  • Improved Gradle build files


You can get the new version as a Maven artifact from Maven Central or JitPack.

Also check out the project on GitHub.

We recommend upgrading to this patch release for all HiveMQ MQTT Client library users.

Have a great day,

Silvio from the HiveMQ Team
