W3C Web Accessibility Initiative (WAI) update — What's in it for you

Shawn Lawton Henry and Kevin White will give updates on WCAG 2, WCAG 3, and resources to focus on the user experiences of disabled people.

With great sadness we learned yesterday of the peaceful passing of @npub10sh5...m4qw last Saturday. In the last 14 years, as a W3C Invited Expert, Gregg co-edited 9 standards and a dozen other specs. He also implemented them all and contributed test suites that #w3c groups are still using. His implication in the JSON-LD Working Group, that he co-chaired, was instrumental to the success of JSON-LD. For all this, but also his friendliness and good nature, he will be dearly missed.

Sad news: Gregg Kellogg passed away from Coralie Mercier on 2025-09-11 (semantic-web@w3.org from September 2025)

W3C tech: "PNG has been updated for the first time in 22 years — new spec supports HDR and animation" "According to ProgramMax, the U.S. Library of Congress, Library and Archives Canada, and the National Archives of Australia recommend PNG for archiving digital images, likely because of its lossless compression. With this amount of trust placed on the file format, it must keep up with the times and ensure that it will continue to help preserve our visual history."
