Create React App 5.0.1 is a maintenance release that improves compatibility with React 18. We've also updated our templates to use createRoot and relaxed our check for older versions of Create React App.
Inside any created project that has not been ejected, run:
npm install --save --save-exact react-scripts@5.0.1
or
yarn add --exact react-scripts@5.0.1

Create React App 5.0 is a major release with several new features and the latest version of all major dependencies.
Thanks to all the maintainers and contributors who worked so hard on this release! 🙌
Inside any created project that has not been ejected, run:
npm install --save --save-exact react-scripts@5.0.0
or
yarn add --exact react-scripts@5.0.0
NOTE: You may need to delete your node_modules folder and reinstall your dependencies by running npm install (or yarn) if you encounter errors after upgrading.
If you previously ejected but now want to upgrade, one common solution is to find the commits where you ejected (and any subsequent commits changing the configuration), revert them, upgrade, and later optionally eject again. It’s also possible that the feature you ejected for is now supported out of the box.
Like any major release, react-scripts@5.0.0 contains a number of breaking changes. We expect that they won't affect every user, but we recommend you look over this section to see if something is relevant to you. If we missed something, please file a new issue.
Node 10 reached End-of-Life in April 2021 and Node 12 will be End-of-Life in April 2022. Going forward we will only support the latest LTS release of Node.js.

We've upgraded to ESLint 7 and added many new rules including some for Jest and React Testing Library as well as the import/no-anonymous-default-export rule. We've also upgraded eslint-plugin-hooks to version 4.0.0 and removed the EXTEND_ESLINT flag as it is no longer required to customize the ESLint config.
We've upgraded to Jest 26 and now set resetMocks to true by default in the Jest config.
We've switched to the Workbox InjectManifest plugin and moved the PWA templates into their own repository.
typescript flag and NODE_PATH supportWe've removed the deprecated typescript flag when creating a new app. Use --template typescript instead. We've also dropped deprecated NODE_PATH flag as this has been replaced by setting the base path in jsconfig.json.
We've changed the loading order of env files to match the dotenv specification. See #9037 for more details.
Node 8 reached End-of-Life at the end of 2019 and is no longer supported.

Create React App 3.0 brings some exciting new features including support for Hooks!
Thanks to all the maintainers and contributors who worked so hard on this release! :tada:

We've updated from Jest 23 to get the latest improvements in Jest 24. We've noticed some differences in snapshot serialization in Jest 24, so you may need to adjust your tests slightly once you update. You can read more about what's changed in the Jest 24 blog post.
We now enforce Rules of Hooks with eslint-plugin-react-hooks. If you are breaking any of the rules of Hooks this will cause your build to fail.
We now lint TypeScript files. You can see the list of rules we enforce to check if your project is compatible. If you're using Visual Studio Code you can follow our guide to setup up your editor to display lint warnings.
browserslist support in @babel/preset-envThe browserslist config in your package.json is now used to control the output of your JavaScript files. You can use separate configuration for development and production. See here for a good starting point which gives a good development experience, especially when using language features such as async/await, but still provides high compatibility with many browsers in production
We've removed the --no-watch flag from the start script in favor of Jest's own --watchAll=false.
asset-manifest.jsonAll asset paths have been moved under the files key in asset-manifest.json.
jsconfig.json/tsconfig.jsonWe now support setting baseUrl in jsconfig.json and tsconfig.json. To configure baseUrl to point to the src directory in your JavaScript project, create a jsconfig.json file in your project root:
```json
{
"compilerOptions": {
"baseUrl": "src"
},
"include": ["src"]
}
```
If you have a TypeScript project you can configure baseUrl the same way in your tsconfig.json.
Currently the only supported options for baseUrl are node_modules (the default) and src.
You can now include a version of Normalize.css in your project that will use your browserslist setting to generate the appropriate styles for your target browsers. To include it simply add @import-normalize at the top of one of your CSS files.
