title: OAuth 2.0 -- What's new?
body: <p>Could someone enumerate the main differences between OAuth 2.0 and previous versions? Or point me to good documentation. (Not the full <a href="https://datatracker.ietf.org/doc/html/draft-ietf-oauth-v2-08" rel="nofollow noreferrer">OAuth 2.0 Protocol draft</a>; I don't have time to read it.)</p>
