The W3 has published the first public draft of PNG, "Third Edition." I share a link to the changelog between the second and third editions:

Looks quite cool! HDR and wide gamut are surging, which I like.

Thanks. I don't think I'll add support for the new cICP chunk until I get a sample for testing. I think this the the only change that impacts ExifTool.
