+**Added**
+- Self-serve listing on `/submit` — enter your domain to validate your `releases.json` manifest and activate listing immediately; valid manifests show a plain-language preview of detected release locations with an activate button for unlisted domains; invalid manifests display field-level errors with a re-check loop. New `POST /v1/listing/validate` and `POST /v1/listing/activate` endpoints support the same flow for API and agent callers.
+
+**Changed**
+- Changelog pages load faster — `/changelog` routes now render markdown server-side; shiki and react-markdown no longer ship to the browser on these pages.
