For historical reference, the previous version of MQTT v3.1 is available here.
MQTT-SN v1.2, formerly known as MQTT-S, is available here. MQTT for Sensor Networks is aimed at embedded devices on non-TCP/IP networks, such as Zigbee. MQTT-SN is a publish/subscribe messaging protocol for wireless sensor networks (WSN), with the aim of extending the MQTT protocol beyond the reach of TCP/IP infrastructure for Sensor and Actuator solutions. Read more about it at the IBM Zurich Research website.
We encourage you to explore (and contribute to!) the mqtt.org wiki for examples and background, but these are some of the longer and more formal documents on MQTT.
