A new PNG spec

10 months ago

A new PNG specification has been released after over 20 years of stagnation.
Key updates include proper HDR support, recognition of APNGs (animated PNGs), and official support for Exif data.
The update also includes general improvements like fixing errata and clarifications.
The push for updates came from the need for HDR support in subtitles, leading to contributions from major tech companies and organizations.
Many popular programs and platforms already support the new PNG spec, including Chrome, Safari, Firefox, and Photoshop.
Future updates are planned, focusing on better compression and parallel encoding/decoding, with the next edition improving HDR and SDR interoperability.
