9.0.0-RC1

Added

• Device Authorization Grant added (PR #1074)
• GrantTypeInterface has a new function, revokeRefreshTokens() for enabling or disabling refresh tokens after use (PR #1375)
• A CryptKeyInterface to allow developers to change the CryptKey implementation with greater ease (PR #1044)
• The authorization server can now finalize scopes when a client uses a refresh token (PR #1094)
• An AuthorizationRequestInterface to make it easier to extend the AuthorizationRequest (PR #1110)
• Added function getKeyContents() to the CryptKeyInterface (PR #1375)

Fixed

• If a refresh token has expired, been revoked, cannot be decrypted, or does not belong to the correct client, the server will now issue an invalid_grant error and a HTTP 400 response. In previous versions the server incorrectly issued an invalid_request and HTTP 401 response (PR #1042) (PR #1082)

Changed

• Authorization Request objects are now created through the factory method, createAuthorizationRequest() (PR #1111)
• Changed parameters for finalizeScopes() to allow a reference to an auth code ID (PR #1112)
• AccessTokenEntityInterface now requires the implementation of toString() instead of the magic method __toString() (PR #1395)

Removed

• Removed message property from OAuthException HTTP response. Now just use error_description as per the OAuth 2 spec (PR #1375)
