on GitHub

OAuth 1 & 2 provider API refactor with breaking changes:

• All endpoint methods change contract to return 3 values instead of 4. The new
  signature is headers, body, status code where the initial redirect_uri
  has been relocated to its rightful place inside headers as Location.
• OAuth 1 Access Token Endpoint has a new required validator method
  invalidate_request_token.
• OAuth 1 Authorization Endpoint now returns a 200 response instead of 302 on
  oob callbacks.
