React Native March 2017 (v0.43.0) released


Everybody Rejoice! Improved API and performances for `List Views` in `React Native` are coming!  
The upcoming `React Native March 2017` will introduce

## [FlatList](https://facebook.github.io/react-native/releases/next/docs/flatlist.html)

```javascript
<FlatList
  data={[{title: 'Title Text', key: 'item1'}, ...]}
  renderItem={({item}) => <ListItem title={item.title}}
/>
```

## [SectionList](https://facebook.github.io/react-native/releases/next/docs/sectionlist.html)

```javascript
<SectionList
  renderItem={({item}) => <ListItem title={item.title}}
  renderSectionHeader={({section}) => <H1 title={section.key} />}
  sections={[ // homogenous rendering between sections
    {data: [...], key: ...},
    {data: [...], key: ...},
    {data: [...], key: ...},
  ]}
/>

<SectionList
  sections={[ // heterogeneous rendering between sections
    {data: [...], key: ..., renderItem: ...},
    {data: [...], key: ..., renderItem: ...},
    {data: [...], key: ..., renderItem: ...},
  ]}
/>
```

## [VirtualizedList](https://facebook.github.io/react-native/releases/next/docs/virtualizedlist.html)

### Features

> Lists are used in many contexts, so we packed the new components full of features to handle the majority of use cases out of the box:
>
> - Scroll loading (onEndReached).
> - Pull to refresh (onRefresh / refreshing).
> - Configurable viewability (VPV) callbacks (onViewableItemsChanged / viewabilityConfig).
> - Horizontal mode (horizontal).
> - Intelligent item and section separators.
> - Multi-column support (numColumns) scrollToEnd, scrollToIndex, and scrollToItem
> - Better Flow typing.

Better List Views in React Native


How many `React Native` Navigation solutions are just too many?  
We don't know yet, keep 'em coming!

AirBnB joins the race for the best `React Native` Navigation solution with its `Native Navigation`

## [Native Navigation](http://airbnb.io/native-navigation/).

## [native-navigation](https://github.com/airbnb/native-navigation) on GitHub

> Native Navigation is a navigation library for the React Native platform. There are many navigation libraries in the React Native ecosystem. Native Navigation is unique in that it is built on top of  
> the iOS and Android platform navigational components, and is this more "native" than most other  
> options which implement navigation from scratch in JavaScript on top of base React Native components  
> like `View` and `Animated`.
>
> [React Native Navigation](https://github.com/wix/react-native-navigation) by Wix engineering is an alternative library that uses "Native" navigation components of each platform, and has been around  
> longer than `Native Navigation`. If you need a stable / production-ready navigation library _today_  
> that uses native platform based navigation components, we recommend you check this library out.
>
> If you are investigating navigation solutions and you are okay with JavaScript-based solutions, we  
> also encourage you to check out [React Navigation](https://reactnavigation.org/).


Native Navigation


[React Conf](http://conf.reactjs.org) is back this year and so are some new exciting announcements. News is out that [Create React Native App](https://github.com/react-community/create-react-native-app) is now officially out.

If you used [CRA](https://github.com/facebookincubator/create-react-app) before then you will already know that this will let you create a bootstrapped app with some simple commands.

```
$ npm i -g create-react-native-app
$ create-react-native-app my-project
$ cd my-project
$ npm start
```

This will let you develop pure `JavaScript` applications, if you then will need to wrap native libraries then you can run `npm run eject` and `react-native link` as you would normally do after a `react-native init`.

React Native February 2017 (v0.42.0) released


## [v0.41.0](https://github.com/facebook/react-native/releases/tag/v0.41.0) on GitHub ([npm](https://www.npmjs.com/package/react-native))

---

This is 0.41.0 release, referred to as "January 2017" according to the new release schedule.

## New features

### Android: Nodes

> This feature is currently experimental. You can turn it on by applying [this](https://github.com/facebook/react-native/tree/master/ReactAndroid/src/main/java/com/facebook/react/flat#how-to-test) in your `ReactNativeHost` subclass.

Nodes is an experimental, alternate version of UIImplementation for ReactNative on Android. It has two main advantages over the existing UIImplementation:

- Support for `overflow:visible` on Android.
- More efficient generation of view hierarchies.

The intention is to ultimately replace the existing UIImplementation on Android with Nodes (after all the issues are ironed out).

Feature development and bug-fixes related to `Nodes` are listed below in a separate section for better clarity.

Check the [readme](https://github.com/facebook/react-native/tree/master/ReactAndroid/src/main/java/com/facebook/react/flat) for more details.

## Breaking changes

### Android: Change ReactNativeHost getUseDeveloperSupport to public

> [f3c8158](https://github.com/facebook/react-native/commit/f3c8158773edf418833ff0032414433edbc6cd62) - [@jpshelley](https://github.com/jpshelley)

This changes the visibility of `getUseDeveloperSupport` from `protected` to `public`. In order to upgrade, you should replace the following in your `MainApplication.java`:

protected boolean getUseDeveloperSupport() {

with

public boolean getUseDeveloperSupport() {

### Android: ReactClippingViewGroup is moved to another package

> [57ebb98](https://github.com/facebook/react-native/commit/57ebb98d1900bdacd94521ae99fd45cb1d22ec8e) - [@astreet](https://github.com/astreet)

Developers using `ReactClippingViewGroup` may need to update their imports from:

import com.facebook.react.views.view.ReactClippingViewGroupHelper;

to

import com.facebook.react.uimanager.ReactClippingViewGroupHelper;
