<div style="font-family:Calibri,sans-serif; font-size:11pt">Fair questions, Justin. First, this is not the Implementer's Draft release. A few more changes still need to be made to get there, including the ones you're mentioning about discovery and registration
and also IdP initiated login. This was an interim release to keep Connect on sync with JWT. Because of the JWT changes, Connect would have been broken without this release.<br>
<br>
The same isn't true of the discovery and registration changes. There, I think the working group's conservative approach, while still encouraging experimentation with the new specs, remains a good stance for the upcoming implementer's drafts. We cam discuss
that more on tomorrow's call if you like (7am Pacific).<br>

Happy New Year!<br>

<div class="moz-cite-prefix">It surprises me that the very fundamental user_id -> sub breaking change was introduced in this revision, but the group wanted to hold back on both registration and discovery until after this publication so as to limit the number
of deep compatibility breaks. I guess what I don't understand is the willingness to break things in one area but hesitance in others, especially since the user_id -> sub change came up only very recently. Don't get me wrong, I'm very much in favor of *all*
of these changes, but I don't understand the logic in how we're deciding what gets broken and when.<br>
<br>
Also, as I recall the discussion, both of these documents were supposed to have a note at the top of them pointing them to the appropriate upstream draft (oauth2-dyn-reg and webfinger, respectively) as an impending change. I can only guess that these notes
got lost during the holiday shuffle and the barrage of JOSE-related changes, but if there's any good way to get these pointers in place, I believe we should do so.<br>

<p class="MsoNormal">New versions of the OpenID Connect specifications have been released resolving numerous open issues raised by the working group. The most significant change is changing the name of the <span style="font-family:"Courier New"">user_id</span>
claim to <span style="font-family:"Courier New"">sub</span> (subject) so that ID Tokens conform to the
<a href="http://tools.ietf.org/html/draft-ietf-oauth-jwt-bearer-04">OAuth JWT Bearer Profile specification</a>, and so they can be used as OAuth assertions. (Also, see the related
<a href="http://self-issued.info/?p=916">coordinated change to the OAuth JWT specifications</a>.) A related enhancement was extending our use of the <span style="font-family:"Courier New"">aud</span> (audience) claim to allow ID Tokens to have multiple audiences.
Also, a related addition was defining the <span style="font-family:"Courier New"">azp</span> (authorized party) claim to allow implementers to experiment with this proposed functionality. (This is a slightly more general form of the <span style="">cid</span>
claim that Google and Nat Sakimura had proposed.)</p>
