Most of the outstanding design issues were discussed at the last IETF meeting and had clear resolutions. As such, I think we're close to being ready to ship this draft.
One issue not discussed(#48 <https://github.com/quicwg/ack-frequency/issues/48>) regarding ECN CE and a new issue(#65 <https://github.com/quicwg/ack-frequency/issues/65>) adding a NO_ACK frame are notable changes and have not received wide discussion, so I wanted to publicize them here before merging any changes. I think both changes are heading in the right direction, and both have PRs you can comment on. I'd like to merge these in a week or so if there's no pushback, so please take a look when you have time. Thanks, Ian
