Hi all,

this version most importantly updates the recommendations for Mix-Up
mitigation, building upon
https://tools.ietf.org/html/draft-ietf-oauth-iss-auth-resp-00. The
description of Mix-Up attacks has also been improved.

Smaller changes:

   * Make the use of metadata RECOMMENDED for both servers and clients
   * Make announcing PKCE support in metadata the RECOMMENDED way
(before: either metadata or deployment-specific way)
   * AS also MUST NOT expose open redirectors.
   * Mention that attackers can collaborate.
   * Make HTTPS mandatory for most redirect URIs.

I'll present more details in the interim meeting next monday.

As always, your feedback is appreciated. We hope that we can proceed to
a WGLC for this document soon.

-Daniel
