 #### :rocket: New Feature
+
 * `react-scripts`
-  * [#1489](https://github.com/facebookincubator/create-react-app/pull/1489) Support setting "homepage" to "." to generate relative asset paths. ([@tibdex](https://github.com/tibdex))

+  * [#1489](https://github.com/facebookincubator/create-react-app/pull/1489) Support setting `"homepage"` to `"."` to generate relative asset paths. ([@tibdex](https://github.com/tibdex))
+
+    Applications that don’t use the HTML5 `pushState` API can now be built to be served from any relative URL. To enable this, specify `"."` as your `homepage` setting in `package.json`. It used to be possible before with a few known bugs, but they should be fixed now. See [Serving the Same Build from Different Paths](https://github.com/facebookincubator/create-react-app/blob/master/packages/react-scripts/template/README.md#serving-the-same-build-from-different-paths).
+
   * [#937](https://github.com/facebookincubator/create-react-app/pull/1504) Add `PUBLIC_URL` env variable for advanced use. ([@EnoahNetzach](https://github.com/EnoahNetzach))
+  
+  If you use a CDN to serve the app, you can now specify `PUBLIC_URL` environment variable to override the base URL (including the hostname) for resources referenced from the built code. This new variable is mentioned in the new [Advanced Configuration](https://github.com/facebookincubator/create-react-app/blob/master/packages/react-scripts/template/README.md#advanced-configuration) section.
+  
   * [#1440](https://github.com/facebookincubator/create-react-app/pull/1440) Make all react env vars accessible in index.html. ([@jihchi](https://github.com/jihchi))
+  
+  This makes all environment variables previously available in JS, also available in the HTML file, for example `%REACT_APP_MY_VARIABLE%`. See [Referencing Environment Variables in HTML](https://github.com/facebookincubator/create-react-app/blob/master/packages/react-scripts/template/README.md#referencing-environment-variables-in-the-html).
+  
 * `react-dev-utils`
+
   * [#1148](https://github.com/facebookincubator/create-react-app/pull/1148) Configure which browser to open in npm start (#873). ([@GAumala](https://github.com/GAumala))
 
-    You can now disable the automatic browser launching by setting the `BROWSER` environment variable to `none`.
+    You can now disable the automatic browser launching by setting the `BROWSER` environment variable to `none`. You can also specify a different browser (or an arbitrary script) to open by default, [as supported by `opn` command](https://github.com/sindresorhus/opn#app) that we use under the hood. See [Advanced Configuration](https://github.com/facebookincubator/create-react-app/blob/master/packages/react-scripts/template/README.md#advanced-configuration).

+Then, run your tests. If you are affected by breaking changes from Jest 18, consult [blog post](https://facebook.github.io/jest/blog/2016/12/15/2016-in-jest.html), [changelog](https://github.com/facebook/jest/blob/master/CHANGELOG.md#jest-1800), and [documentation](http://facebook.github.io/jest/docs/getting-started.html).
