+## 1.2.0 (June 21, 2016)
+* fix: remove `whatwg-fetch` polyfill, due problem in React Native ([issue #8](https://github.com/nodkz/react-relay-network-layer/issues/8)).
+
+If your client does not have `fetch` global method, you should include polyfill explicitly in you code:
+```js
+  import 'whatwg-fetch'; // for old browsers
+  or
+  import 'node-fetch';  // for old node versions
+  or
+  import 'fetch-everywhere'; // fresh isomorphic fetch polyfill, that supports all clients (not tested ;)
+```
+Thanks to @roman01la and @edvinerikson.
+
 ## 1.1.4 (June 15, 2016)
 * feat: add `allowEmptyToken` option for `authMiddleware` to allow made a request without Authorization header if token is empty

 The `ReactRelayNetworkLayer` is a [Relay Network Layer](https://facebook.github.io/relay/docs/guides-network-layer.html)
 with query batching and middleware support.
 
-Main purpose to use this NetworkLayer:
+This NetworkLayer solves following problems:
 - If your app is making enough individual queries to be a performance problem on first page load
-- If your app should manipulate request on the fly - log them, change or made some fallbacks if request fails
+- If your app should manipulate request/responce on the fly - change auth headers, request url or made some fallbacks if request fails
+
+Can be used in browser, react-native or node server for rendering. Under the hood this module uses global `fetch` method. So if your client is too old, please import explicitly proper polyfill to your code  (eg. `whatwg-fetch`, `node-fetch` or `fetch-everywhere`).
 
 Available middlewares:
 - **url** - for manipulating fetch `url` on fly via thunk. Options:
