This update focuses on restoring reliable IndexNow support for sites using custom domains. If you rely on IndexNow for faster search engine indexing, custom domain changelogs now work as expected again.
Fixes for IndexNow on custom domains
IndexNow submissions now use the host taken directly from the URLs you submit, instead of a hardcoded host. This ensures that search engines see the correct domain for each submitted URL, which is required for proper indexing.
We also added a route that serves the IndexNow key file on custom domains. With the key file now available on the same domain as your changelog URLs, IndexNow can successfully verify ownership and process your submissions.
