3.0.1 RC2 fixes a CMS regression since 3.0.0 where Add Forms of GridField would require a full CMS refresh after visiting, most obviously affecting the "Add Member" area of the Security admin panel.
In addition it restores GridField image embedding functionality from the 3.0 beta series that regressed in 3.0.0, most obviously restoring the image thumbnails to the Files admin panel.
There should be no changes required to upgrade from 3.0.0 or 3.0.1-rc1
See 3.0.0 for previous details.
