New numbering system for V7 releases

New numbering system for V7 releases

As of July 2019, the naming convention for T3 V7 releases is changing to make the product version number more meaningful.  The version numbers will now be 7. yy . ww  where  yy  is the year and  ww  is the week of the year.  This does not have any impact on the installation / upgrade procedure.
