Re: Agenda items for Monday 23 June

I just cancelled the meeting. Oops.
But that's probably fine. These topics probably don't require a meeting.
Email is likely sufficient.

5.) I am also working on a little announcement post for when Third Edition
becomes a Recommendation. I had previously worked on a CICP post but hadn't
updated it after comments. I'll be sure to link to your post :D

6.) I believe the plan is to create a branch for Third Edition and leave
tip-of-tree as the current edition. That will then effectively become an
inactive branch. (We can also mark it as a release on that branch.)
