There are three new components in this release:
1) an Android Service based on the Paho Java MQTT client library, which sends and receives messages on behalf of an Android client application when the application's main Activity may not be running.
2) MQTT and MQTT-SN client libraries in C for embedded devices with limited resources - for instance mbed and Arduino microcontrollers.
3) An MQTT client for .Net and WinRT, written in C#
along with updated (bug-fixed) versions of the existing components: MQTT client libraries for Java, C/C++, Python and JavaScript.
