Intel Edison @ MQTT

Hi,

When looking at https://communities.intel.com/servlet/JiveServlet/previewBody/23272-102-1-27335/Edison%20101%20Presentation%20from%20IDF… and https://intel.activeevents.com/sf14/connect/fileDownload/session/210DAAEA9629A64A85EF96815CF78A67/SF14_EDTS003_101f.pdf in the release 1 software stack - middleware I see MQTT is present. Does this mean MQTT library is part of Intel Edison software stack or do I need to add a third-party MQTT client library?

Thanks.

Guy
