@steinybot The CI build failed! Please review the logs for more information.

Once you've pushed the fixes, the build will automatically re-run. Thanks!

Note: builds which are failing do not end up on the list of PRs for the DT maintainers to review.

SuspenseList is not part of react@^18.0.0 but react@experimental. While the PR made that change, SuspenseList was later removed from the stable entrypoint

[typescript-bot]

@steinybot One or more reviewers has requested changes. Please address their comments. I'll be back once they sign off or you've pushed new commits. Thank you!

[steinybot]

@eps1lon It seems you are right: https://codesandbox.io/s/react-suspense-list-d993mu?file=/src/App.tsx

The comment at the top of experimental.d.ts says:

// See https://github.com/facebook/react/blob/master/packages/react/src/React.js to see how the exports are declared,
// and https://github.com/facebook/react/blob/master/packages/shared/ReactFeatureFlags.js to verify which APIs are
// flagged experimental or not. Experimental APIs will be tagged with `__EXPERIMENTAL__`.

That comment really should say to look in https://github.com/facebook/react/blob/main/packages/react/index.stable.js. I've been searching for ages trying to work it out and only now spotted that there is a different file.

[eps1lon]

Documentation and https://unpkg.com/react et al. are usually best to identify what ends up being available.

[Jessidhia]

That comment really should say to look in https://github.com/facebook/react/blob/main/packages/react/index.stable.js.

This was likely a refactoring done in the React side after that comment was written 😇
