- Chrome now enforces that servers on private networks explicitly grant access to public websites using a new header "Access-Control-Allow-Private-Network" that should be sent in responses to preflight OPTIONS requests. - This change implements special handling for OPTIONS requests by sending all the existing CORS headers along with the new Access-Control-Allow-Private-Network header if private network access is being requested. - See https://developer.chrome.com/blog/private-network-access-preflight/ for more info.
