Preparing for the Future with React Prereleases (reactjs.org)
Oct 22, 2019
To share upcoming changes with our partners in the React ecosystem, we’re establishing official prerelease channels. We hope this process will help us make changes to React with confidence, and give developers the opportunity to try out experimental features.
React v16.0 (reactjs.org)
Sep 26, 2017
We’re excited to announce the release of React v16.0! Among the changes are some long-standing feature requests, including fragments, error boundaries, portals, support for custom DOM attributes, improved server-side rendering, and reduced file size.
React v15.5.0 (reactjs.org)
Apr 07, 2017
It’s been exactly one year since the last breaking change to React. Our next major release, React 16, will include some exciting improvements, including a complete rewrite of React’s internals. We take stability seriously, and are committed to bringing those improvements to all of our users with minimal effort.
