It didn't reset anything.  However, last call ended on 8/11 and now we all have to figure  out what to do about this document.

OK, thanks.  But I'm really unclear what you want the reviewers to do with it.

There seems to be no point in continung with the review of -12 as if nothing has happened.  My assumption was that you decided to go with a new approach to security in -13 and wanted the review to proceed on that basis, as Spencer indicated should happen given that -13 substantially changed what was in -12.

If that isn't right, it would be best if you supply a -14 that has the document that you would like to get reviewed as the basis for WGLC and if not tell the working group that the document is now no longer ready for WGLC review.

The changes in v13 were in response to the WGLC, including the ones to the security. And
while the churn to the document was substantial, the effective changes to the protocol
were not that substantial.

I do not want to see what would effectively be an open ended WGLC that gets reset
every time a review is made. That sets a precedent I do not want to endorse.

There is a need to adress the issue of a last call for flex-files-13.

I previously suggested extending the -12 LC to encompass the -13 and ending on 8/21, but Spencer on 8/8 responded:.

Since that last call ended on 8/11, the version available now is we have to start that new last call.

Wait, I would have held off shipping a v-13 if I had known it reset the last call.

I sent out v-13 as a courtesy to the reviewers.

I think it is pretty clear that there has been enough change.  If there is anyone who disagrees, please speak up..

The only remaIning issue is the the end date.  I previously proposed a two-week last call period to enable me to do
a comprehensive review.  Others might want to focus on the security changes in -13 but I skipped a comprehensive
review of -12 because it was always pretty clear there would have to be a -13.

Two weeks from today would be 8/29.  However, it may be simpler to make the end date the following Fridiay, which is 9/1.
Is Tom and the rest of the working group OK with that end date for the -13 WGLC?

Once that is complete, we will start another last call on the version of the I-D that is available then.

Note that this is always the case - if there has been enough change during a last call to warrant another round, then we do another last call.  Not a big deal.

I can't see reviewing this by 8/11.  I think we will need to reset the WGLC clock.

I thibk it should be extended  to 8/21 to give us two weeks to review the new draft.  Other opinions?

In any case, Spencer S should announce a new date, so everybody is in sync.
