Looking good! Just a few things that you could consider updating.

1. In the blurb, I found myself unsure what "support" referred to. Browser support? Financial support? So here are ideas for clarifying that just a bit.
   "Sponsor support for continued development of the Anchor Position Spec is making the Anchor Position Polyfill more useful. Here's a summary of the latest updates."
   OR
   "Donations from sponsors for continued development of the Anchor Position Spec is making the Anchor Position Polyfill more useful. Here's what's new!"

2. "some of the upcoming ones are-" I would change that to "some of the upcoming ones are:" (Use a colon instead of a dash.)

3. At most screen sizes that I have available to view the header image, I can't see the bottom of the anchor. I see the chains, mostly. Could you re-position the image so that the really recognizable part of the anchor is in view on more screen sizes?
