This worries me. Because presumably, changing the compression algorithm will break backwards compatibility, which means we'll start to see "png" files that aren't actually png files.

It'll be like USB-C but for images.

+1 why not name it png4 or something. It's better if compatibility is obvious upfront

I think if they did that, nobody would use it. And anyway, from the article:

> Many of the programs you use already support the new PNG spec: Chrome, Safari, Firefox, iOS/macOS, Photoshop, DaVinci Resolve, Avid Media Composer...

It might be too late to rename png to .png4 or something. It sounds like we're using the new png standard already in a lot of our software.
