Notes on releases that change what an unchanged configuration does.

| Change | Summary |
| --- | --- |
| [Identity verification is required by default](/authproxy/upgrading/identity-verification-required-by-default/) | A service that has a backend is now verified by its `/.cratis/me` answer, and anything but an explicit positive denies. |
| [Tenant and service headers follow Arc](/authproxy/upgrading/tenant-and-service-headers/) | Both current and legacy tenant and service headers are forwarded during the transition; legacy forwarding is deprecated, and client-supplied tenant headers are stripped. |
