+This document describes the source code for the `Eclipse Paho <http://eclipse.org/paho/>`_ MQTT Python client library, which implements versions 5.0, 3.1.1, and 3.1 of the MQTT protocol.

It also provides some helper functions to make publishing one off messages to an MQTT server very straightforward.
 
-It supports Python 2.7.9+ or 3.4+, with limited support for Python 2.7 before 2.7.9.
+It supports Python 2.7.9+ or 3.5+.

Designed as an extremely lightweight publish/subscribe messaging transport, it is useful for connections with remote locations where a small code footprint is required and/or network bandwidth is at a premium.
