React v17.0: A “Stepping Stone” Release

No new features, but a lot of changes, paving the way for future releases.

The React 17 release is unusual because it doesn’t add any new developer-facing features. Instead, this release is primarily focused on making it easier to upgrade React itself.

We’re actively working on the new React features, but they’re not a part of this release. The React 17 release is a key part of our strategy to roll them out without leaving anyone behind.

In particular, React 17 is a “stepping stone” release that makes it safer to embed a tree managed by one version of React inside a tree managed by a different version of React.

Here are the major changes:

  1. Changes to Event Delegation
  2. No Event Pooling
  3. Effect Cleanup Timing Change
  4. Consistent Errors for Returning undefined
  5. Methods of removing private exports
