OK! What we have in this branch, as I can see:

• The new front page itself, in public/index.php
• Frontend support files:
  • include/branch-highlights.inc: frontend-targeted descriptions of highlights of each release
  • public/styles/theme-gst.css and public/js/common.js
  • Many new images
• A "theme" rendering framework in src/Themes
• A new footer design (and new body wrapper, if needed, in the header), opt-in per page: include/header.inc and footer.inc only switch behavior when a page sets $config['include_section'] = false / $config['footer_style'] = 'new'
• An updated version release data layer, founded in src/Releases/Branches.php

Here is a screenshot, since we don't have this on a preview branch:

Tasks I think we need to do in order to move forward with this:

• Review any changes made to the non-template code
• Review changes to content
• Review changes to design

I feel like I'm most equipped to be a part of the content and design conversations; as I haven't been really involved in the PHP.net site before, I'd love to leave the first item to others (not sure if @derickr has had a chance to review all this code yet; if not, it'd be great if someone could volunteer to do that.)

I'll leave another comment in a minute about my thoughts, and those I've gathered from others, about content and design.
