- Test on Node.js >=22. - Update `engines.node` to `>=22`. - Update README requirements section.
- Improve formatting. - Add more common README sections.
- `kyOriginalPromise` no longer exported. - `ky` is again exported. - Change from using `ky` promises to regular instances.
- After `ky@2` update the error body is already available in `error.data` and trying to get JSON again will fail.
- Remove `push`. - Add `query`, `options`, and `trace` to align with `ky@2`.
ky@2 merges header options via a plain object spread when both sides are still plain objects, which does not dedupe names that differ only by case (e.g. `Accept` vs `accept`), causing values to be appended instead of overridden. Use a `Headers` instance instead. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>
- Fix import. - Use suggested ChromeHeadless options for CI.
Webpack's browser field remaps `tests/utils.js` to `tests/utils-browser.js`, but the browser stub never defined `makeAgent`. The namespace import in the shared spec file only references it inside an `isNode` guard, but webpack still statically validates the export, breaking the karma build.

Adding a non-simple header (e.g. `Authorization`) triggers a browser CORS preflight `OPTIONS` request, which this route never answered, causing the actual request to be blocked. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>
`ky@2` wraps the browser's `TypeError: Failed to fetch` in its own `NetworkError`, with the original error moved to `cause`. Check both locations so the friendly CORS message still gets applied. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>
Launch the browser with `--ignore-certificate-errors` so it accepts the self-signed cert, letting the local HTTPS test server test run in both node and browsers. This covers TLS in the browser without depending on an external site. Restrict the github.com test to node. The site sends no CORS headers, so a browser blocks the request before it is sent. Keeping it node-only also halves how often it runs, reducing rate limit exposure. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>
`engines` requires node >=22, so the node 18.2+ guard on agent conversion is always true. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>

There was a problem hiding this comment.
Seems ok from a glance -- hard to tell, without implementation experience, whether any new strange behavior is introduced.
