-Changes/Bugfixes
-~~~~~~~~~~~~~~~~
-
-**Potentially backward incompatible change**:
-
-Multi-tenant admin classes now allow only org managers.
-
-Before this version, a user needed to be only org member
-to see items of that organization in the admin, but this
-is wrong! An ``OrganizationUser`` which has ``is_admin=False`` is
-only an end-user of that organization.
-Instead, an ``OrganizationUser`` which has ``is_admin=True`` is
-also a manager and only this type of user shall be allowed
-to manage items of the organization through the django admin site.
+Changes
+~~~~~~~
 
-This is needed in order to support users being simple end-users
-in one organization but administrators in others, otherwise
-a staff user who is administrator of one organization would be
-able to change also items of other organizations where
-they are only members and not managers.
