Website is not up-to-date

Dear @pnggroup team,

The website is not up-to-date, it is possible to solve it?

• http://libpng.org/pub/png/libpng.html

Thanks in advance.

Yes, since the maintainer is a member of the pnggroup organisation, however it might help to list the issues which you can see are out-of-date.

With that statement in mind here are some of the issues I know about:

• The "extensions" document itself is (or was a few days ago) out of date. The up-to-date version is here, Extensions to the PNG 1.2 Specification, Version 1.5.0 1.5.1 is required when PNG v3 becomes more than a "candidate recommendation" because the definition of the eXIf chunk has been changed incompatibly and is now part of the core standard, so not technically an "extension", but that's a separate issue as it is not the responsibility of the website maintainer.
• The "Joint W3C and ISO" section here: http://libpng.org/pub/png/png-sitemap.html#info might include a link to the W3C draft pages here: https://www.w3.org/TR/png-3/ Yeah; that is a WIP and who knows how it will change before it gets its head shoved out of the door, but it's basically a link to the deliberation process (sort of) now that png-mng-misc has been sidelined.
• Perhaps some discussion, or at least comments, on how to go about getting new chunks approved?

An alternative to all this is to mark libpng.org "historical", freeze dry it, and rely on github, or wordpress, or something else of a more FOSS nature than either the W3C or ISO, maybe a wiki?, to contain the libpng documentation, such as it is.

Just my comment, since I'm not a member of pnggroup (by design).
