If your code still calls the Workers KV API at /accounts/{account_id}/workers/namespaces/*, those routes are now deprecated. Cloudflare flagged them on July 15 and will stop serving them on October 15. The good news is this is about as gentle as a migration gets: the replacement routes under /storage/kv/namespaces/ take the same parameters and return the same payloads, so it's a find-and-replace on the path — swap /workers/namespaces/ for /storage/kv/namespaces/ and you're done. Nothing breaks today. But anything still hitting the old paths after October 15 starts failing, so it's worth grepping your integrations and CI scripts now rather than during an incident.
