Today, we’re thrilled to launch react.dev, the new home for React and its documentation. It teaches modern React with function components and Hooks, and we’ve included diagrams, illustrations, challenges, and over 600 interactive examples. Check it out!

We’ve just released React 16.8 with a stable version of Hooks. React Hooks let you use features like local state and lifecycle without writing a class. They’re fully backwards-compatible and you can start using them today. reactjs.org/blog/2019/02/06/…
ALT What Are Hooks? Hooks let you use state and other React features without writing a class. You can also build your own Hooks to share reusable stateful logic between components.

Today, we’re releasing the first Release Candidate for React 17! This release is rather unusual: it contains no new features. 👀 reactjs.org/blog/2020/08/10/…
ALT 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.

If your app doesn’t work after upgrading to React 18, the first thing to check is whether it’s wrapped in <StrictMode>. Strict Mode has gotten stricter in 18, but you can turn it off and address issues at your own pace later!
✨ More upgrading tips: reactjs.org/blog/2022/03/08/…
ALT If your app doesn’t work after upgrading, check whether it’s wrapped in <StrictMode>. Strict Mode has gotten stricter in React 18, and not all your components may be resilient to the new checks it adds in development mode. If removing Strict Mode fixes your app, you can remove it during the upgrade, and then add it back (either at the top or for a part of the tree) after you fix the issues that it’s pointing out.
