Thanks for the update, Niall.

I have P1030R3 on the list of papers to schedule for Belfast [1], but I
haven't finished the schedule yet. We're going to be short on time, but
I plan to make time for this paper. Some things that you could do to help:

1) Have a brief introduction prepared that goes over the changes since
R2 and the affect those changes have had on users (e.g., some details
like those you describe below).

2) Review the polls [2] from our review of R2 and for each determine if
there is new information that should lead us to re-poll those
questions. Of course, discussion may lead us to re-polling those if we
determine that significant new information exists any way.

3) Consider any new polls you might like to take for R3.
