1.1.0

🌟 Features

• Reconnect Handling #83
  • Connected and Disconnected listeners
  • Automatic reconnect strategy (exponential backoff + random delays, customizable parameters)
  • Customizable reconnect handling (delay, reconnect when a future completes, alter Connect message, alter transport for high availability)
  • Resending of messages after reconnect (pending + queued, Publishes, Subscribes, Unsubscribes)
  • Setting Auth and Will publish on a client, not only on connect (reused during reconnect)

🐞 Bug fixes

• Fixed mixed ordering of messages when publishing in a very high rate with the AsyncClient #283

⚠️ Behavioral changes

• Rx3/5Client.publish(Flowable): if the session expires the Flowable is not cancelled anymore. Instead the individual publishes are errored. This is the expected behavior, cancelling may devour messages.
