+### Babel Preset (`babel-preset-react-app`)
+
+* Published for the first time! ([@fson](https://github.com/fson) in [#701](https://github.com/facebookincubator/create-react-app/pull/701))
+
+### Utilities (`react-dev-utils`)
+
+* Published for the first time! ([@gaearon](https://github.com/gaearon) in [#723](https://github.com/facebookincubator/create-react-app/pull/723))
+
+### Global CLI (`create-react-app`)
+
+* Added `README` to npm. There were no other changes.
+
+### Migrating from 0.4.3 to 0.5.0
+
+Inside any created project that has not been ejected, run:
+
+```
+npm install --save-dev --save-exact react-scripts@0.5.0
+```
+
+### Breaking Changes in 0.5.0
+
+#### Global ESLint Plugin Versions
+
+If you used a global ESLint installation for the editor integration, you’ll need to install [these versions of global ESLint packages](https://github.com/facebookincubator/create-react-app/blob/c092086b1b256fd081f10744f90d216dd5217e29/packages/eslint-config-react-app/package.json#L14-L19).
+
+#### Moving `index.html` into `public` Folder
+
+You’ll also need to create a new folder called `public` in the root of your project. Then, move `index.html` and files it references (such as a favicon) into that folder.
+
+You can no longer reference any files from `./src` in `index.html`. Instead, `public/index.html` can now only reference files other inside of the `public` folder using a special variable called `%PUBLIC_URL%`.
+
+For example, instead of:
+
+```js
+<link rel="shortcut icon" href="./src/favicon.ico">
+```
+
+You would need to move both `index.html` and `src/favicon.ico` into the `public` folder, and change `<link>` to look like this:
+
+```html
+<link rel="shortcut icon" href="%PUBLIC_URL%/favicon.ico">
+```
+
+This ensures it become a part of the build output, and resolves correctly both with client-side routing and non-root `homepage` in `package.json`. Read more about [using the `public` folder](https://github.com/facebookincubator/create-react-app/blob/master/packages/react-scripts/template/README.md#using-the-public-folder) and [why these changes were made](https://github.com/facebookincubator/create-react-app/pull/703).
