Planned annual upgrade of Moodle VLE platform.  

 We should be upgrading yearly, but jumping 2 versions at a time (upgrading in June/July each year).  The exact version each year will be dependent on our plugins and how quickly they can be tested/redeveloped by non-Moodle HQ developers. At present we expect to deploy in July the version that comes out in the December previous.  

Annual upgrade of Moodle platform to stay on supported version. Takes place in Semester 2 for delivery into production in July to fit with teaching pattern.
