Agenda items for Monday 23 June

Mostly announcements:

1. PNG 3rd Edition will become a W3C Recommendation on Tues 24 June
https://github.com/w3c/transitions/issues/725
   (There is a one-week delay between requesting transition to 
Recommendation and publishing, so the 24th was the earliest date)

2. Mozilla, who originally proposed APNG back in the day, announced they 
are happy to see it in PNG 3rd Edition:

> Mozilla is proud to support PNG 3e in Firefox and grateful for the 
> work the Working Group put into this specification including 
> incorporating the prior APNG specification developed on the Mozilla 
> Wiki (https://wiki.mozilla.org/APNG_Specification).
>
> See and feel free to contribute to this bug (or its dependencies) 
> regarding the implementation of PNG 3e in Firefox: 
> https://bugzilla.mozilla.org/show_bug.cgi?id=495609
where it says

> APNG has been incorporated into the W3C PNG Third Edition 
> specification. Updated bug title and specification URL accordingly.
>
> Since we should no longer be directly implementing the prior APNG 
> Specification, but as a meta task still should "finish" implementing 
> and fixing bugs in APNG, made sense to re-use this meta bug to keep 
> history/lineage/dependencies rather than file a new meta bug and 
> create a bunch of Bugzilla notification noise.
>
3. Servo, the emerging web engine written in Rust, has an issue to 
implement APNG and someone is on it
https://github.com/issues/created?issue=servo%7Cservo%7C37493

4. pnggroup, which maintains libpng, has a pull request from Cosmin 
Truta for APNG support in libpng v2
https://github.com/pnggroup/libpng/pull/706

5. I'm writing a blog post which is a deep dive on CICP, and I plan to 
announce it the same day PNG 3rd Edition becomes a Recommendation

and a question

6. It would be good to be clear how we handle 3rd Edition and 4th 
Edition, in terms of GitHub branches, so everyone is clear going forward.

Specifically, I need to check in changes from Proposed Recommendation (a 
changes section that says "Changes from Proposed Recommendation: none") 
and a (currently empty) errata list, and then how to check in a first 
draft of Fourth Edition whose title says Fourth Edition and whose 
changes section is currently empty except for "Changes from Third 
Edition: none".
