HDR and EXIF are great changes… APNG, if already being used for some apps/services, seems a logic choice. Maybe it’ll finally mean the end of gifs once and for all?

What I’m more excited for though, is the improvements in compression that the article hints that are being worked on. Specially if it can beat other more modern formats that have added lossless compression like jpegxl. I feel it’s best to have separate formats for lossless and lossy, to prevent the off-chance of lossyness getting through.
