What Microsoft changed
Month-dated announcementAdded the authenticationBehaviors resource type and the coopEnforcement property to the v1.0 endpoint. Application owners can use the property to explicitly test Cross-Origin-Opener-Policy enforcement, temporarily suppress enforcement while remediating an incompatible browser authentication flow, or return to the service default. The property is available in the global service only and isn't available in national cloud deployments.
