I can't find the Default Role.
In the Spring 2014 release, the Default Role label was changed to Admin Privileges. This means that every place in the system that previously referenced the Default Role, now shows Admin Privileges. Note that the role names (and the access levels assigned them) shown in the drop-down lists have not changed.
Note that this is the role granted to all new member accounts. It determines the areas of the system they can access and the types of administration or system configuration changes they can make. To learn more, see Admin Privileges.
Where was this change made?
You can see this change on the following pages:
