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.

Better compression can also mean a new set of filter methods or a new interlacing algorithm. But yeah, any of them would cause an instant incompatibility. As noted in the relevant issue [1], we will need a new media type at the very least.

We would need a new media type. But the actual new features don't need one, because the news don't break compatibility.

https://svgees.us/blog/img/revoy-cICP-bt.2020.png uses the new colour space. If your software and monitor can handle it, you see better colour than I, otherwise, you see what I see.
