The "offline_access" scope value was defined to request that a refresh token be returned when using the code flow that can be used to obtain an access token granting access to the user's UserInfo endpoint even when the user is not present.
A new "tos_url" registration parameter was added so that the terms of service can be specified separately from the usage policy.
Clarified that "jwk_url" and "jwk_encryption_url" refer to documents containing JWK Sets – not single JWK keys.
See the Document History section of each specification for more details about the changes made.
