React Versions – React
The React docs at react.dev provide documentation for the latest version of React.
We aim to keep the docs updated within major versions, and do not publish versions for each minor or patch version. When a new major is released, we archive the docs for the previous version as x.react.dev. See our versioning policy for more info.
You can find an archive of previous major versions below.
In 2023, we launched our new docs for React 18 as react.dev. The legacy React 18 docs are available at legacy.reactjs.org. Versions 17 and below are hosted on legacy sites.
For versions older than React 15, see 15.react.dev.
React was open-sourced on May 29, 2013. The initial commit is: 75897c: Initial public release
