This is such excellent news! Thank you Chris and everyone who helped get it here :-) Best, Chris Seeger Chris Seeger Director, Advanced Content Production Office of the CTO ________________________________ From: Chris Lilley <chris@w3.org> Sent: Friday, June 20, 2025 8:56:08 PM To: public-png@w3.org <public-png@w3.org> Subject: [EXTERNAL] 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<https://urldefense.com/v3/__https://github.com/w3c/transitions/issues/725__;!!PIZeeW5wscynRQ!s1rkUIJQoY2tKkWgbdhLQF_uhWDVpo8VF_32_G2eSdVdYptBKH2rKFHcupE_1dY52xcJpCJ0HkZg3g$> (There is a one-week delay between requesting transition to Recommendation and publishing, so the 24th was the earliest date) 2. Mozilla, who originally proposed APNG back in the day, announced they are happy to see it in PNG 3rd Edition: Mozilla is proud to support PNG 3e in Firefox and grateful for the work the Working Group put into this specification including incorporating the prior APNG specification developed on the Mozilla Wiki (https://wiki.mozilla.org/APNG_Specification<https://urldefense.com/v3/__https://wiki.mozilla.org/APNG_Specification__;!!PIZeeW5wscynRQ!s1rkUIJQoY2tKkWgbdhLQF_uhWDVpo8VF_32_G2eSdVdYptBKH2rKFHcupE_1dY52xcJpCI2yx6X_w$>). 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<https://urldefense.com/v3/__https://bugzilla.mozilla.org/show_bug.cgi?id=495609__;!!PIZeeW5wscynRQ!s1rkUIJQoY2tKkWgbdhLQF_uhWDVpo8VF_32_G2eSdVdYptBKH2rKFHcupE_1dY52xcJpCJjZ0WXBA$> where it says APNG has been incorporated into the W3C PNG Third Edition specification. Updated bug title and specification URL accordingly. Since we should no longer be directly implementing the prior APNG Specification, but as a meta task still should "finish" implementing and fixing bugs in APNG, made sense to re-use this meta bug to keep history/lineage/dependencies rather than file a new meta bug and create a bunch of Bugzilla notification noise. 3. Servo, the emerging web engine written in Rust, has an issue to implement APNG and someone is on it https://github.com/issues/created?issue=servo%7Cservo%7C37493<https://urldefense.com/v3/__https://github.com/issues/created?issue=servo*7Cservo*7C37493__;JSU!!PIZeeW5wscynRQ!s1rkUIJQoY2tKkWgbdhLQF_uhWDVpo8VF_32_G2eSdVdYptBKH2rKFHcupE_1dY52xcJpCKwXUB6LA$> 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<https://urldefense.com/v3/__https://github.com/pnggroup/libpng/pull/706__;!!PIZeeW5wscynRQ!s1rkUIJQoY2tKkWgbdhLQF_uhWDVpo8VF_32_G2eSdVdYptBKH2rKFHcupE_1dY52xcJpCIIuVPa9Q$> 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". -- Chris Lilley @svgeesus@mastodon.scot Technical Director @ W3C W3C Technical Programming Team, Core Web Design
