Hi all,
the most important changes for this version are as follows:
* New advice: For public clients, nonce is not sufficient to protect
against authorization code injection. PKCE is now a MUST for public
clients.
* We have refined the guidance on using nonce for code injection
protection, for example if multiple ID tokens are returned
("response_type=code id_token").
* The draft now covers the PKCE Downgrade Attack and countermeasures.
Authorization servers MUST follow special rules when allowing
non-PKCE and PKCE flows for the same client.
* Native apps with a "localhost" redirect URI can be exempt from exact
redirect URI matching: Port numbers may differ, as in RFC8252,
Section 7.3.
* And finally, some clarifications on refresh token
sender-constraining and mTLS.
