Release Notes

facebook/create-react-app

### [`v3.4.3`](https://togithub.com/facebook/create-react-app/blob/master/CHANGELOG.md#​343-2020-08-12) [Compare Source](https://togithub.com/facebook/create-react-app/compare/d2f813f8897ffcd2f0b0d2da75d0c44924c92f4d...d2f813f8897ffcd2f0b0d2da75d0c44924c92f4d) v3.4.2 release bumps `terser-webpack-plugin` to a version for which `npm audit` does not report a vulnerability. Note that **this vulnerability did not affect Create React App projects**, so this change is only necessary to satisfy auditing tools. ##### Migrating from 3.4.2 to 3.4.3 Inside any created project that has not been ejected, run: ```sh npm install --save --save-exact react-scripts@3.4.3 ``` or ```sh yarn add --exact react-scripts@3.4.3 ```
