### Migrating from 0.2.0 to 0.2.1
Update `react-scripts` to point to `0.2.1` in your `package.json` and run `npm install`. You shouldn’t need to do anything else. If you see a warning about wrong file casing next time you `npm start`, fix your imports to use the correct filename casing.
Newly created projects will use `0.2.1` automatically. You **don’t** need to update the global `create-react-app` CLI itself. It stays at `0.2.0` for now because it doesn’t have any changes.
