Why is Adafruit not accepting this pull request? Wanted to modify the library by myself, but then I found your fork. I would have made the same changes as you did. Good work! |

The last value is the retained flag. Setting it to zero will not publish the topic as retained. Setting it to anything else will. |

Added a 'retain' flag for the
Adafruit_MQTT_Publishclass. When set, published topics will be saved on the broker so later subscriptions will receive the message as well.In order to remove this topic from the broker, one must publish a message with no (i.e. zero-length) content.
By default, this flag is unset to keep the current behavior.
