PNG is back!

A new PNG spec was just released! […]

[…] After 20 years of stagnation, PNG is back with renewed vigor!

What's new?

* Proper HDR support (future‐proof, too!)

* Finally recognizes APNGs (animations!)

* Officially supports Exif data

* General tidying up—fixing errata, clarifications, etc.

@knurd42 can we finally get proper arithmetic coding support?
I know it has been in the spec, but maybe this time.
Also 32 bit png anytime?
