 ## Features
 - Transfer data directly from/to storage without BASE64 bridging
 - File API supports normal files, Asset files, and CameraRoll files
 - Native-to-native file manipulation API, reduce JS bridging performance loss
 - File stream support for dealing with large file
-- Blob, File, XMLHttpRequest polyfills that make browser-based library available in RN
+- Blob, File, XMLHttpRequest polyfills that make browser-based library available in RN (experimental)

 Beginning in Android 6.0 (API level 23), users grant permissions to apps while the app is running, not when they install the app. So adding permissions in `AndroidManifest.xml` won't work in Android 6.0 devices. To grant permissions in runtime, you might use modules like [react-native-android-permissions](https://github.com/lucasferreira/react-native-android-permissions).

-#### Android Media Scanner, and Download Manager Support
+### RNFetchBlob as Fetch
+
+0.9.0
+
+If you have existing code that uses `whatwg-fetch`(the official **fetch**), you don't have to change them after 0.9.0, just use fetch replacement. The difference between Official fetch and fetch replacement is, official fetch uses [whatwg-fetch](https://github.com/github/fetch) js library which wraps XMLHttpRequest polyfill under the hood it's a great library for web developers, however that does not play very well with RN. Our implementation is simply a wrapper of  RNFetchBlob.fetch and fs APIs, so you can access all the features we provide.

+**Open Downloaded File with Intent**

+This is a new feature added in `0.9.0`, if you're going to open a file path using official [Linking](https://facebook.github.io/react-native/docs/linking.html) API that might not work as expected, also, if you're going to install an APK in `Downloads` app, that will not work too. As an alternative, you can try `actionViewIntent` API, which will send an ACTION_VIEW intent for you which uses the given `MIME` type.

 ### Performance Tips

-**Reduce RCT Bridge Overhead and BASE64 Time**
+**Reduce RCT Bridge and BASE64 Overheard**
 
 React Native connects JS and Native context by passing JSON through React bridge, therefore there will be an overhead to convert data before they sent. When data is large, this will be quite a performance impact to your app, it's recommended to use file storage instead of BASE64 if possible. The following chart shows how much faster when loading data from storage than BASE64 encoded string on iphone 6.
