To announce updated license texts. (12th August 2014)

MS1/Extra - new license file clarifies copyright.
MS2/Extra is unchanged.
MS3 license text updated to include MS3-Pro.

A combined text is available to view/download at

I would like to remind resellers that it is a license condition that a printed copy of the firmware license is included with any products that are supplied with firmware pre-loaded. The PDF sheet is designed to be printed out and included with your shipments.

The licenses are renewed periodically, that date sets an end for the current license documents. Do note that the date would only impacts new sales in any case.
