Key changes include unified hook handling where all hooks now receive a single state object, a new totalTimeout option that caps the entire operation across retries, cleaner URL handling with a renamed prefix option and a new baseUrl option following standard URL resolution, and built-in response validation via Standard Schema supporting Zod, Valibot, and compatible validators. HTTPError now exposes a pre-parsed data property to avoid resource leaks. The release requires Node.js 22 and includes a full migration guide with before-and-after examples for breaking changes. ## Full article daily.dev links to this article rather than hosting it.
