A new version of the Grid format for Moodle 3.0: https://moodle.org/plugins/pluginversion.php?id=11481 - thanks to Justin Hunt and Mark Sharp for most of the updates:
1. Updated php4 constructor - #27 - thanks to Mark Sharp.
2. Added the ability to grey out and unlink grid icons for unavailable sections - #30 - thanks to Justin Hunt.
3. Travis CI fixes.
4. Fixes for #30 in IE.
This fixes a few things and now paves the way to make the M3.1 version - due date TBD.
