+
+## 15.0.1 (April 8, 2016)

+
+### ReactDOM
+- Fixed issue resulting in loss of cursor position in controlled inputs. ([@spicyj](https://github.com/spicyj) in [#6449](https://github.com/facebook/react/pull/6449))
+
+
+## 15.0.0 (April 7, 2016)
+
+### Major changes
+
+- **Initial render now uses `document.createElement` instead of generating HTML.** Previously we would generate a large string of HTML and then set `node.innerHTML`. At the time, this was decided to be faster than using `document.createElement` for the majority of cases and browsers that we supported. Browsers have continued to improve and so overwhelmingly this is no longer true. By using `createElement` we can make other parts of React faster. ([@spicyj](https://github.com/spicyj) in [#5205](https://github.com/facebook/react/pull/5205))
+- **`data-reactid` is no longer on every node.** As a result of using `document.createElement`, we can prime the node cache as we create DOM nodes, allowing us to skip a potential lookup (which used the `data-reactid` attribute). Root nodes will have a `data-reactroot` attribute and server generated markup will still contain `data-reactid`. ([@spicyj](https://github.com/spicyj) in [#5205](https://github.com/facebook/react/pull/5205))
+- **No more extra `<span>`s.** ReactDOM will now render plain text nodes interspersed with comment nodes that are used for demarcation. This gives us the same ability to update individual pieces of text, without creating extra nested nodes. If you were targeting these `<span>`s in your CSS, you will need to adjust accordingly. You can always render them explicitly in your components. ([@mwiencek](https://github.com/mwiencek) in [#5753](https://github.com/facebook/react/pull/5753))
+- **Rendering `null` now uses comment nodes.** Previously `null` would render to `<noscript>` elements. We now use comment nodes. This may cause issues if making use of `:nth-child` CSS selectors. While we consider this rendering behavior an implementation detail of React, it's worth noting the potential problem. ()[@spicyj](https://github.com/spicyj) in [#5451](https://github.com/facebook/react/pull/5451))
+- **Functional components can now return `null`.** We added support for [defining stateless components as functions](/react/blog/2015/09/10/react-v0.14-rc1.html#stateless-function-components) in React 0.14. However, React 0.14 still allowed you to define a class component without extending `React.Component` or using `React.createClass()`, so [we couldn’t reliably tell if your component is a function or a class](https://github.com/facebook/react/issues/5355), and did not allow returning `null` from it. This issue is solved in React 15, and you can now return `null` from any component, whether it is a class or a function. ([@jimfb](https://github.com/jimfb) in [#5884](https://github.com/facebook/react/pull/5884))
+- **Improved SVG support.** All SVG tags are now fully supported. (Uncommon SVG tags are not present on the `React.DOM` element helper, but JSX and `React.createElement` work on all tag names.) All SVG attributes that are implemented by the browsers should be supported too. If you find any attributes that we have missed, please [let us know in this issue](https://github.com/facebook/react/issues/1657). ([@zpao](https://github.com/zpao) in [#6243](https://github.com/facebook/react/pull/6243))
+
+### Breaking changes
+
+- **No more extra `<span>`s.**
+- **`React.cloneElement()` now resolves `defaultProps`.** We fixed a bug in `React.cloneElement()` that some components may rely on. If some of the `props` received by `cloneElement()` are `undefined`, it used to return an element with `undefined` values for those props. We’re changing it to be consistent with `createElement()`. Now any `undefined` props passed to `cloneElement()` are resolved to the corresponding component’s `defaultProps`. ([@truongduy134](https://github.com/truongduy134) in [#5997](https://github.com/facebook/react/pull/5997))
+- **`ReactPerf.getLastMeasurements()` is opaque.** This change won’t affect applications but may break some third-party tools. We are [revamping `ReactPerf` implementation](https://github.com/facebook/react/pull/6046) and plan to release it during the 15.x cycle. The internal performance measurement format is subject to change so, for the time being, we consider the return value of `ReactPerf.getLastMeasurements()` an opaque data structure that should not be relied upon. ([@gaearon](https://github.com/gaearon) in [#6286](https://github.com/facebook/react/pull/6286))
+
+#### Removed deprecations
+
+These deprecations were introduced nine months ago in v0.14 with a warning and are removed:
+
+- Deprecated APIs are removed from the `React` top-level export: `findDOMNode`, `render`, `renderToString`, `renderToStaticMarkup`, and `unmountComponentAtNode`. As a reminder, they are now available on `ReactDOM` and `ReactDOMServer`. ([@jimfb](https://github.com/jimfb) in [#5832](https://github.com/facebook/react/pull/5832))
+- Deprecated addons are removed: `batchedUpdates` and `cloneWithProps`. ([@jimfb](https://github.com/jimfb) in [#5859](https://github.com/facebook/react/pull/5859), [@zpao](https://github.com/zpao) in [#6016](https://github.com/facebook/react/pull/6016))
+- Deprecated component instance methods are removed: `setProps`, `replaceProps`, and `getDOMNode`. ([@jimfb](https://github.com/jimfb) in [#5570](https://github.com/facebook/react/pull/5570))
+- Deprecated CommonJS `react/addons` entry point is removed. As a reminder, you should use separate `react-addons-*` packages instead. This only applies if you use the CommonJS builds. ([@gaearon](https://github.com/gaearon) in [#6285](https://github.com/facebook/react/pull/6285))
+- Passing `children` to void elements like `<input>` was deprecated, and now throws an error. ([@jonhester](https://github.com/jonhester) in [#3372](https://github.com/facebook/react/pull/3372))
+- React-specific properties on DOM `refs` (e.g. `this.refs.div.props`) were deprecated, and are removed now. ([@jimfb](https://github.com/jimfb) in [#5495](https://github.com/facebook/react/pull/5495))
+
+### New deprecations, introduced with a warning
+
+Each of these changes will continue to work as before with a new warning until the release of React 16 so you can upgrade your code gradually.
+
+- `LinkedStateMixin` and `valueLink` are now deprecated due to very low popularity. If you need this, you can use a wrapper component that implements the same behavior: [react-linked-input](https://www.npmjs.com/package/react-linked-input). ([@jimfb](https://github.com/jimfb) in [#6127](https://github.com/facebook/react/pull/6127))
+- Future versions of React will treat `<input value={null}>` as a request to clear the input. However, React 0.14 has been ignoring `value={null}`. React 15 warns you on a `null` input value and offers you to clarify your intention. To fix the warning, you may explicitly pass an empty string to clear a controlled input, or pass `undefined` to make the input uncontrolled. ([@antoaravinth](https://github.com/antoaravinth) in [#5048](https://github.com/facebook/react/pull/5048))
+- `ReactPerf.printDOM()` was renamed to `ReactPerf.printOperations()`, and `ReactPerf.getMeasurementsSummaryMap()` was renamed to `ReactPerf.getWasted()`. ([@gaearon](https://github.com/gaearon) in [#6287](https://github.com/facebook/react/pull/6287))
+
+### New helpful warnings
+
+- If you use a minified copy of the _development_ build, React DOM kindly encourages you to use the faster production build instead. ([@spicyj](https://github.com/spicyj) in [#5083](https://github.com/facebook/react/pull/5083))
+- React DOM: When specifying a unit-less CSS value as a string, a future version will not add `px` automatically. This version now warns in this case (ex: writing `style={{'{{'}}width: '300'}}`. Unitless *number* values like `width: 300` are unchanged. ([@pluma](https://github.com/pluma) in [#5140](https://github.com/facebook/react/pull/5140))
+- Synthetic Events will now warn when setting and accessing properties (which will not get cleared appropriately), as well as warn on access after an event has been returned to the pool. ([@kentcdodds](https://github.com/kentcdodds) in [#5940](https://github.com/facebook/react/pull/5940) and [@koba04](https://github.com/koba04) in [#5947](https://github.com/facebook/react/pull/5947))
+- Elements will now warn when attempting to read `ref` and `key` from the props. ([@prometheansacrifice](https://github.com/prometheansacrifice) in [#5744](https://github.com/facebook/react/pull/5744))
+- React will now warn if you pass a different `props` object to `super()` in the constructor. ([@prometheansacrifice](https://github.com/prometheansacrifice) in [#5346](https://github.com/facebook/react/pull/5346))
+- React will now warn if you call `setState()` inside `getChildContext()`. ([@raineroviir](https://github.com/raineroviir) in [#6121](https://github.com/facebook/react/pull/6121))
+- React DOM now attempts to warn for mistyped event handlers on DOM elements, such as `onclick` which should be `onClick`. ([@ali](https://github.com/ali) in [#5361](https://github.com/facebook/react/pull/5361))
+- React DOM now warns about `NaN` values in `style`. ([@jontewks](https://github.com/jontewks) in [#5811](https://github.com/facebook/react/pull/5811))
+- React DOM now warns if you specify both `value` and `defaultValue` for an input. ([@mgmcdermott](https://github.com/mgmcdermott) in [#5823](https://github.com/facebook/react/pull/5823))
+- React DOM now warns if an input switches between being controlled and uncontrolled. ([@TheBlasfem](https://github.com/TheBlasfem) in [#5864](https://github.com/facebook/react/pull/5864))
+- React DOM now warns if you specify `onFocusIn` or `onFocusOut` handlers as they are unnecessary in React. ([@jontewks](https://github.com/jontewks) in [#6296](https://github.com/facebook/react/pull/6296))
+- React now prints a descriptive error message when you pass an invalid callback as the last argument to `ReactDOM.render()`, `this.setState()`, or `this.forceUpdate()`. ([@conorhastings](https://github.com/conorhastings) in [#5193](https://github.com/facebook/react/pull/5193) and [@gaearon](https://github.com/gaearon) in [#6310](https://github.com/facebook/react/pull/6310))
+- Add-Ons: `TestUtils.Simulate()` now prints a helpful message if you attempt to use it with shallow rendering. ([@conorhastings](https://github.com/conorhastings) in [#5358](https://github.com/facebook/react/pull/5358))
+- PropTypes: `arrayOf()` and `objectOf()` provide better error messages for invalid arguments. ([@chicoxyzzy](https://github.com/chicoxyzzy) in [#5390](https://github.com/facebook/react/pull/5390))
+
+### Notable bug fixes
+
+- Fixed multiple small memory leaks. ([@spicyj](https://github.com/spicyj) in [#4983](https://github.com/facebook/react/pull/4983) and [@victor-homyakov](https://github.com/victor-homyakov) in [#6309](https://github.com/facebook/react/pull/6309))
+- Input events are handled more reliably in IE 10 and IE 11; spurious events no longer fire when using a placeholder. ([@jquense](https://github.com/jquense) in [#4051](https://github.com/facebook/react/pull/4051))
+- The `componentWillReceiveProps()` lifecycle method is now consistently called when `context` changes. ([@milesj](https://github.com/milesj) in [#5787](https://github.com/facebook/react/pull/5787))
+- `React.cloneElement()` doesn’t append slash to an existing `key` when used inside `React.Children.map()`. ([@ianobermiller](https://github.com/ianobermiller) in [#5892](https://github.com/facebook/react/pull/5892))
+- React DOM now supports the `cite` and `profile` HTML attributes. ([@AprilArcus](https://github.com/AprilArcus) in [#6094](https://github.com/facebook/react/pull/6094) and [@saiichihashimoto](https://github.com/saiichihashimoto) in [#6032](https://github.com/facebook/react/pull/6032))
+- React DOM now supports `cssFloat`, `gridRow` and `gridColumn` CSS properties. ([@stevenvachon](https://github.com/stevenvachon) in [#6133](https://github.com/facebook/react/pull/6133) and  [@mnordick](https://github.com/mnordick) in [#4779](https://github.com/facebook/react/pull/4779))
+- React DOM now correctly handles `borderImageOutset`, `borderImageWidth`, `borderImageSlice`, `floodOpacity`, `strokeDasharray`, and `strokeMiterlimit` as unitless CSS properties. ([@rofrischmann](https://github.com/rofrischmann) in [#6210](https://github.com/facebook/react/pull/6210) and [#6270](https://github.com/facebook/react/pull/6270))
+- React DOM now supports the `onAnimationStart`, `onAnimationEnd`, `onAnimationIteration`, `onTransitionEnd`, and `onInvalid` events. Support for `onLoad` has been added to `object` elements. ([@tomduncalf](https://github.com/tomduncalf) in [#5187](https://github.com/facebook/react/pull/5187),  [@milesj](https://github.com/milesj) in [#6005](https://github.com/facebook/react/pull/6005), and [@ara4n](https://github.com/ara4n) in [#5781](https://github.com/facebook/react/pull/5781))
+- React DOM now defaults to using DOM attributes instead of properties, which fixes a few edge case bugs. Additionally the nullification of values (ex: `href={null}`) now results in the forceful removal, no longer trying to set to the default value used by browsers in the absence of a value. ([@syranide](https://github.com/syranide) in [#1510](https://github.com/facebook/react/pull/1510))
+- React DOM does not mistakingly coerce `children` to strings for Web Components. ([@jimfb](https://github.com/jimfb) in [#5093](https://github.com/facebook/react/pull/5093))

+- React DOM no longer forces synchronous layout because of scroll position tracking. ([@syranide](https://github.com/syranide) in [#2271](https://github.com/facebook/react/pull/2271))
+- `Object.is` is used in a number of places to compare values, which leads to fewer false positives, especially involving `NaN`. In particular, this affects the `shallowCompare` add-on. ([@chicoxyzzy](https://github.com/chicoxyzzy) in [#6132](https://github.com/facebook/react/pull/6132))
+- Add-Ons: ReactPerf no longer instruments adding or removing an event listener because they don’t really touch the DOM due to event delegation. ([@antoaravinth](https://github.com/antoaravinth) in [#5209](https://github.com/facebook/react/pull/5209))
+
+### Other improvements
+
+- React now uses `loose-envify` instead of `envify` so it installs fewer transitive dependencies. ([@qerub](https://github.com/qerub) in [#6303](https://github.com/facebook/react/pull/6303))
+- Shallow renderer now exposes `getMountedInstance()`. ([@glenjamin](https://github.com/glenjamin) in [#4918](https://github.com/facebook/react/pull/4918))
+- Shallow renderer now returns the rendered output from `render()`. ([@simonewebdesign](https://github.com/simonewebdesign) in [#5411](https://github.com/facebook/react/pull/5411))
+- React no longer depends on ES5 *shams* for `Object.create` and `Object.freeze` in older environments. It still, however, requires ES5 *shims* in those environments. ([@dgreensp](https://github.com/dgreensp) in [#4959](https://github.com/facebook/react/pull/4959))
+- React DOM now allows `data-` attributes with names that start with numbers. ([@nLight](https://github.com/nLight) in [#5216](https://github.com/facebook/react/pull/5216))
+- React DOM adds a new `suppressContentEditableWarning` prop for components like [Draft.js](https://facebook.github.io/draft-js/) that intentionally manage `contentEditable` children with React. ([@mxstbr](https://github.com/mxstbr) in [#6112](https://github.com/facebook/react/pull/6112))
+- React improves the performance for `createClass()` on complex specs. ([@spicyj](https://github.com/spicyj) in [#5550](https://github.com/facebook/react/pull/5550))

+
+
+## 0.14.0 (October 7, 2015)
+
+### Major changes
+
+- Split the main `react` package into two: `react` and `react-dom`.  This paves the way to writing components that can be shared between the web version of React and React Native.  This means you will need to include both files and some functions have been moved from `React` to `ReactDOM`.
+- Addons have been moved to separate packages (`react-addons-clone-with-props`, `react-addons-create-fragment`, `react-addons-css-transition-group`, `react-addons-linked-state-mixin`, `react-addons-perf`, `react-addons-pure-render-mixin`, `react-addons-shallow-compare`, `react-addons-test-utils`, `react-addons-transition-group`, `react-addons-update`, `ReactDOM.unstable_batchedUpdates`).
+- Stateless functional components - React components were previously created using React.createClass or using ES6 classes.  This release adds a [new syntax](https://facebook.github.io/react/docs/reusable-components.html#stateless-functions) where a user defines a single [stateless render function](https://facebook.github.io/react/docs/reusable-components.html#stateless-functions) (with one parameter: `props`) which returns a JSX element, and this function may be used as a component.
+- Refs to DOM components as the DOM node itself. Previously the only useful thing you can do with a DOM component is call `getDOMNode()` to get the underlying DOM node. Starting with this release, a ref to a DOM component _is_ the actual DOM node. **Note that refs to custom (user-defined) components work exactly as before; only the built-in DOM components are affected by this change.**
+
+
+### Breaking changes
+
+- `React.initializeTouchEvents` is no longer necessary and has been removed completely. Touch events now work automatically.
+- Add-Ons: Due to the DOM node refs change mentioned above, `TestUtils.findAllInRenderedTree` and related helpers are no longer able to take a DOM component, only a custom component.
+- The `props` object is now frozen, so mutating props after creating a component element is no longer supported. In most cases, [`React.cloneElement`](https://facebook.github.io/react/docs/top-level-api.html#react.cloneelement) should be used instead. This change makes your components easier to reason about and enables the compiler optimizations mentioned above.
+- Plain objects are no longer supported as React children; arrays should be used instead. You can use the [`createFragment`](https://facebook.github.io/react/docs/create-fragment.html) helper to migrate, which now returns an array.
+- Add-Ons: `classSet` has been removed. Use [classnames](https://github.com/JedWatson/classnames) instead.
+- Web components (custom elements) now use native property names.  Eg: `class` instead of `className`.
+
+### Deprecations
+
+- `this.getDOMNode()` is now deprecated and `ReactDOM.findDOMNode(this)` can be used instead. Note that in the common case, `findDOMNode` is now unnecessary since a ref to the DOM component is now the actual DOM node.
+- `setProps` and `replaceProps` are now deprecated. Instead, call ReactDOM.render again at the top level with the new props.
+- ES6 component classes must now extend `React.Component` in order to enable stateless function components. The [ES3 module pattern](https://facebook.github.io/react/blog/2015/01/27/react-v0.13.0-beta-1.html#other-languages) will continue to work.
+- Reusing and mutating a `style` object between renders has been deprecated. This mirrors our change to freeze the `props` object.
+- Add-Ons: `cloneWithProps` is now deprecated. Use [`React.cloneElement`](https://facebook.github.io/react/docs/top-level-api.html#react.cloneelement) instead (unlike `cloneWithProps`, `cloneElement` does not merge `className` or `style` automatically; you can merge them manually if needed).
+- Add-Ons: To improve reliability, `CSSTransitionGroup` will no longer listen to transition events. Instead, you should specify transition durations manually using props such as `transitionEnterTimeout={500}`.
+
+### Notable enhancements
+
+- Added `React.Children.toArray` which takes a nested children object and returns a flat array with keys assigned to each child. This helper makes it easier to manipulate collections of children in your `render` methods, especially if you want to reorder or slice `this.props.children` before passing it down. In addition, `React.Children.map` now returns plain arrays too.
+- React uses `console.error` instead of `console.warn` for warnings so that browsers show a full stack trace in the console. (Our warnings appear when you use patterns that will break in future releases and for code that is likely to behave unexpectedly, so we do consider our warnings to be “must-fix” errors.)
+- Previously, including untrusted objects as React children [could result in an XSS security vulnerability](http://danlec.com/blog/xss-via-a-spoofed-react-element). This problem should be avoided by properly validating input at the application layer and by never passing untrusted objects around your application code. As an additional layer of protection, [React now tags elements](https://github.com/facebook/react/pull/4832) with a specific [ES2015 (ES6) `Symbol`](http://www.2ality.com/2014/12/es6-symbols.html) in browsers that support it, in order to ensure that React never considers untrusted JSON to be a valid element. If this extra security protection is important to you, you should add a `Symbol` polyfill for older browsers, such as the one included by [Babel’s polyfill](http://babeljs.io/docs/usage/polyfill/).
+- When possible, React DOM now generates XHTML-compatible markup.
+- React DOM now supports these standard HTML attributes: `capture`, `challenge`, `inputMode`, `is`, `keyParams`, `keyType`, `minLength`, `summary`, `wrap`. It also now supports these non-standard attributes: `autoSave`, `results`, `security`.
+- React DOM now supports these SVG attributes, which render into namespaced attributes: `xlinkActuate`, `xlinkArcrole`, `xlinkHref`, `xlinkRole`, `xlinkShow`, `xlinkTitle`, `xlinkType`, `xmlBase`, `xmlLang`, `xmlSpace`.
+- The `image` SVG tag is now supported by React DOM.
+- In React DOM, arbitrary attributes are supported on custom elements (those with a hyphen in the tag name or an `is="..."` attribute).
+- React DOM now supports these media events on `audio` and `video` tags: `onAbort`, `onCanPlay`, `onCanPlayThrough`, `onDurationChange`, `onEmptied`, `onEncrypted`, `onEnded`, `onError`, `onLoadedData`, `onLoadedMetadata`, `onLoadStart`, `onPause`, `onPlay`, `onPlaying`, `onProgress`, `onRateChange`, `onSeeked`, `onSeeking`, `onStalled`, `onSuspend`, `onTimeUpdate`, `onVolumeChange`, `onWaiting`.
+- Many small performance improvements have been made.
+- Many warnings show more context than before.
+- Add-Ons: A [`shallowCompare`](https://github.com/facebook/react/pull/3355) add-on has been added as a migration path for `PureRenderMixin` in ES6 classes.
+- Add-Ons: `CSSTransitionGroup` can now use [custom class names](https://github.com/facebook/react/blob/48942b85/docs/docs/10.1-animation.md#custom-classes) instead of appending `-enter-active` or similar to the transition name.
+
+### New helpful warnings
+
+- React DOM now warns you when nesting HTML elements invalidly, which helps you avoid surprising errors during updates.
+- Passing `document.body` directly as the container to `ReactDOM.render` now gives a warning as doing so can cause problems with browser extensions that modify the DOM.
+- Using multiple instances of React together is not supported, so we now warn when we detect this case to help you avoid running into the resulting problems.
+
+### Notable bug fixes
+
+- Click events are handled by React DOM more reliably in mobile browsers, particularly in Mobile Safari.
+- SVG elements are created with the correct namespace in more cases.
+- React DOM now renders `<option>` elements with multiple text children properly and renders `<select>` elements on the server with the correct option selected.
+- When two separate copies of React add nodes to the same document (including when a browser extension uses React), React DOM tries harder not to throw exceptions during event handling.
+- Using non-lowercase HTML tag names in React DOM (e.g., `React.createElement('DIV')`) no longer causes problems, though we continue to recommend lowercase for consistency with the JSX tag name convention (lowercase names refer to built-in components, capitalized names refer to custom components).
+- React DOM understands that these CSS properties are unitless and does not append “px” to their values: `animationIterationCount`, `boxOrdinalGroup`, `flexOrder`, `tabSize`, `stopOpacity`.
+- Add-Ons: When using the test utils, `Simulate.mouseEnter` and `Simulate.mouseLeave` now work.
+- Add-Ons: ReactTransitionGroup now correctly handles multiple nodes being removed simultaneously.
+
+
+### React Tools / Babel
+
+#### Breaking Changes
+
+- The `react-tools` package and `JSXTransformer.js` browser file [have been deprecated](https://facebook.github.io/react/blog/2015/06/12/deprecating-jstransform-and-react-tools.html). You can continue using version `0.13.3` of both, but we no longer support them and recommend migrating to [Babel](http://babeljs.io/), which has built-in support for React and JSX.
+
+#### New Features
+
+- Babel 5.8.24 introduces **Inlining React elements:** The `optimisation.react.inlineElements` transform converts JSX elements to object literals like `{type: 'div', props: ...}` instead of calls to `React.createElement`.  This should only be enabled in production, since it disables some development warnings/checks.
+- Babel 5.8.24 introduces **Constant hoisting for React elements:** The `optimisation.react.constantElements` transform hoists element creation to the top level for subtrees that are fully static, which reduces calls to `React.createElement` and the resulting allocations. More importantly, it tells React that the subtree hasn’t changed so React can completely skip it when reconciling.  This should only be enabled in production, since it disables some development warnings/checks.

 # Contributing to React

-React is one of Facebook's first open source projects that is both under very active development and is also being used to ship code to everybody on [facebook.com](https://www.facebook.com). We're still working out the kinks to make contributing to this project as easy and transparent as possible, but we're not quite there yet. Hopefully this document makes the process for contributing clear and answers some questions that you may have.
+Want to contribute to React? There are a few things you need to know.  

-## [Code of Conduct](https://code.facebook.com/codeofconduct)
-
-Facebook has adopted a Code of Conduct that we expect project participants to adhere to. Please read [the full text](https://code.facebook.com/codeofconduct) so that you can understand what actions will and will not be tolerated.
-
-## Our Development Process
-
-Some of the core team will be working directly on GitHub. These changes will be public from the beginning. Other changesets will come via a bridge with Facebook's internal source control. This is a necessity as it allows engineers at Facebook outside of the core team to move fast and contribute from an environment they are comfortable in.
-
-### `master` is unsafe
-
-We will do our best to keep `master` in good shape, with tests passing at all times. But in order to move fast, we will make API changes that your application might not be compatible with. We will do our best to communicate these changes and always version appropriately so you can lock into a specific version if need be.
-
-### Pull Requests
-
-The core team will be monitoring for pull requests. When we get one, we'll run some Facebook-specific integration tests on it first. From here, we'll need to get another person to sign off on the changes and then merge the pull request. For API changes we may need to fix internal uses, which could cause some delay. We'll do our best to provide updates and feedback throughout the process.
-
-*Before* submitting a pull request, please make sure the following is done…
-
-1. Fork the repo and create your branch from `master`.
-2. If you've added code that should be tested, add tests!
-3. If you've changed APIs, update the documentation.
-4. Ensure the test suite passes (`grunt test`).
-5. Make sure your code lints (`grunt lint`) - we've done our best to make sure these rules match our internal linting guidelines.
-6. If you haven't already, complete the CLA.
-
-### Contributor License Agreement (CLA)
-
-In order to accept your pull request, we need you to submit a CLA. You only need to do this once, so if you've done this for another Facebook open source project, you're good to go. If you are submitting a pull request for the first time, just let us know that you have completed the CLA and we can cross-check with your GitHub username.
-
-[Complete your CLA here.](https://code.facebook.com/cla)
-
-## Bugs
-
-### Where to Find Known Issues
-
-We will be using GitHub Issues for our public bugs. We will keep a close eye on this and try to make it clear when we have an internal fix in progress. Before filing a new task, try to make sure your problem doesn't already exist.
-
-### Reporting New Issues
-
-The best way to get your bug fixed is to provide a reduced test case. jsFiddle, jsBin, and other sites provide a way to give live examples. Those are especially helpful though may not work for `JSX`-based code.
-
-### Security Bugs
-
-Facebook has a [bounty program](https://www.facebook.com/whitehat/) for the safe disclosure of security bugs. With that in mind, please do not file public issues; go through the process outlined on that page.
-
-## How to Get in Touch
-
-* IRC - [#reactjs on freenode](https://webchat.freenode.net/?channels=reactjs)
-* Discussion forum - [discuss.reactjs.org](https://discuss.reactjs.org/)
-
-## Style Guide
-
-Our linter will catch most styling issues that may exist in your code.
-You can check the status of your code styling by simply running: `grunt lint`
-
-However, there are still some styles that the linter cannot pick up. If you are unsure about something, looking at [Airbnb's Style Guide](https://github.com/airbnb/javascript) will guide you in the right direction.
-
-### Code Conventions
-
-* Use semicolons `;`
-* Commas last `,`
-* 2 spaces for indentation (no tabs)
-* Prefer `'` over `"`
-* `'use strict';`
-* 80 character line length
-* Write "attractive" code
-* Do not use the optional parameters of `setTimeout` and `setInterval`
-
-### Documentation
-
-* Do not wrap lines at 80 characters

 React is a JavaScript library for building user interfaces.

-* **Just the UI:** Lots of people use React as the V in MVC. Since React makes no assumptions about the rest of your technology stack, it's easy to try it out on a small feature in an existing project.
-* **Virtual DOM:** React abstracts away the DOM from you, giving a simpler programming model and better performance. React can also render on the server using Node, and it can power native apps using [React Native](https://facebook.github.io/react-native/).
-* **Data flow:** React implements one-way reactive data flow which reduces boilerplate and is easier to reason about than traditional data binding.
-
-**NEW**! Check out our newest project [React Native](https://github.com/facebook/react-native), which uses React and JavaScript to create native mobile apps.
+* **Declarative:** React makes it painless to create interactive UIs. Design simple views for each state in your application, and React will efficiently update and render just the right components when your data changes. Declarative views make your code more predictable, simpler to understand, and easier to debug.
+* **Component-Based:** Build encapsulated components that manage their own state, then compose them to make complex UIs. Since component logic is written in JavaScript instead of templates, you can easily pass rich data through your app and keep state out of the DOM.
+* **Learn Once, Write Anywhere:** We don't make assumptions about the rest of your technology stack, so you can develop new features in React without rewriting existing code. React can also render on the server using Node and power mobile apps using [React Native](https://facebook.github.io/react-native/).

A simple transform is included with React that allows converting JSX into native JavaScript for browsers to digest.

JSX is not required to use React, but it makes code more readable, and writing it feels like writing HTML. We recommend using [Babel](https://babeljs.io/) with a [React preset](https://babeljs.io/docs/plugins/preset-react/) to convert JSX into native JavaScript for browsers to digest.

 ## Installation

-The fastest way to get started is to serve JavaScript from the CDN (also available on [cdnjs](https://cdnjs.com/libraries/react) and [jsdelivr](http://www.jsdelivr.com/#!react)):
+React is available as the `react` package on [npm](https://www.npmjs.com/). It is also available on a [CDN](https://facebook.github.io/react/docs/installation.html#using-a-cdn).

-```html
-<!-- The core React library -->
-<script src="https://fb.me/react-0.13.3.js"></script>
-<!-- In-browser JSX transformer, remove when pre-compiling JSX. -->
-<script src="https://fb.me/JSXTransformer-0.13.3.js"></script>
-```
+React is flexible and can be used in a variety of projects. You can create new apps with it, but you can also gradually introduce it into an existing codebase without doing a rewrite.

-We've also built a [starter kit](https://facebook.github.io/react/downloads/react-0.13.3.zip) which might be useful if this is your first time using React. It includes a webpage with an example of using React with live code.
+The recommended way to install React depends on your project. Here you can find short guides for the most common scenarios:

-If you'd like to use [bower](http://bower.io), it's as easy as:
+* [Trying Out React](https://facebook.github.io/react/docs/installation.html#trying-out-react)
+* [Creating a Single Page Application](https://facebook.github.io/react/docs/installation.html#creating-a-single-page-application)
+* [Adding React to an Existing Application](https://facebook.github.io/react/docs/installation.html#adding-react-to-an-existing-application)

-```sh
-bower install --save react
-```

+### [Code of Conduct](https://code.facebook.com/codeofconduct)

-### Building Your Copy of React
+Facebook has adopted a Code of Conduct that we expect project participants to adhere to. Please read [the full text](https://code.facebook.com/codeofconduct) so that you can understand what actions will and will not be tolerated.

-The process to build `react.js` is built entirely on top of node.js, using many libraries you may already be familiar with.
+### Good First Bug

-#### Prerequisites
-
-* You have `node` installed at v0.10.0+ (it might work at lower versions, we just haven't tested) and `npm` at v2.0.0+.
-* You are familiar with `npm` and know whether or not you need to use `sudo` when installing packages globally.
-* You are familiar with `git`.
-
-#### Build
-
-Once you have the repository cloned, building a copy of `react.js` is really easy.
-
-```sh
-# grunt-cli is needed by grunt; you might have this installed already
-npm install -g grunt-cli
-npm install
-grunt build
-```
-
-At this point, you should now have a `build/` directory populated with everything you need to use React. The examples should all work.
-
-### Grunt
-
-We use grunt to automate many tasks. Run `grunt -h` to see a mostly complete listing. The important ones to know:
-
-```sh
-# Build and run tests with PhantomJS
-grunt test
-# Build and run tests in your browser
-grunt test --debug
-# Lint the code with ESLint
-grunt lint
-# Wipe out build directory
-grunt clean
-```
+To help you get your feet wet and get you familiar with our contribution process, we have a list of [good first bugs](https://github.com/facebook/react/labels/good%20first%20bug) that contain bugs which are fairly easy to fix. This is a great place to get started.
