  • (react-dom/server) renderToReadableStream
  • ReactDOM.render is no longer supported in React 18. Use createRoot instead. Until you switch to the new API, your app will behave as if it’s running React 17. Learn more: https://reactjs.org/link/switch-to-createroot
  • if your app uses server-side rendering with hydration, upgrade hydrate to hydrateRoot
  • We’ve also changed unmountComponentAtNode to root.unmount
  • We’ve also removed the callback from render
  • react-dom: ReactDOM.hydrate has been deprecated. Using it will warn and run your app in React 17 mode.
  • react-dom: ReactDOM.render has been deprecated. Using it will warn and run your app in React 17 mode.
  • react-dom: ReactDOM.renderSubtreeIntoContainer has been deprecated.
  • react-dom: ReactDOM.unmountComponentAtNode has been deprecated.
  • react-dom/server: ReactDOMServer.renderToNodeStream has been deprecated.
  • renderToNodeStream is deprecated
  • renderToStaticNodeStream exists apparently
  • set globalThis.IS_REACT_ACT_ENVIRONMENT to true before running your test
  • Components can now render undefined
  • Deprecate renderIntoDOM
  • Add a callback attr (?)
  • Deprecate Mounted component types
  • Add a downstream-test to check React 17 still works
