 - **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))

([@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).

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`.

 - `setProps` and `replaceProps` are now deprecated. Instead, call ReactDOM.render again at the top level with the new props.

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 a CDN. We're using [unpkg](https://unpkg.com/) below but React is also available on [cdnjs](https://cdnjs.com/libraries/react) and [jsdelivr](https://www.jsdelivr.com/projects/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://unpkg.com/react@15.4.0/dist/react.js"></script>
-<!-- The ReactDOM Library -->
-<script src="https://unpkg.com/react-dom@15.4.0/dist/react-dom.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-15.4.0.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:
-
-```sh
-bower install --save react
-```
-
-And it's just as easy with [npm](http://npmjs.com):
-
-```sh
-npm i --save react
-```

+>**Note:**
+>This is a legacy React addon, and is no longer maintained.
+>
+>We don't encourage using it in new code, but it exists for backwards compatibility.  
+>The recommended migration path is to use arrays with explicit keys on individual elements.
+
+**Importing**
+
+```javascript
+import createFragment from 'react-addons-create-fragment'; // ES6
+var createFragment = require('react-addons-create-fragment'); // ES5 with npm
+```
+
+If you prefer a `<script>` tag, you can get it from `React.addons.createFragment` with:
+
+```html
+<!-- development version -->
+<script src="https://unpkg.com/react-addons-create-fragment/react-addons-create-fragment.js"></script>
+
+<!-- production version -->
+<script src="https://unpkg.com/react-addons-create-fragment/react-addons-create-fragment.min.js"></script>
+```
+
+In this case, make sure to put the `<script>` tag after React.
+
+## Overview
+
+In most cases, you can use the `key` prop to specify keys on the elements you're returning from `render`. However, this breaks down in one situation: if you have two sets of children that you need to reorder, there's no way to put a key on each set without adding a wrapper element.
+
+That is, if you have a component such as:
+
+```js
+function Swapper(props) {
+  let children;
+  if (props.swapped) {
+    children = [props.rightChildren, props.leftChildren];
+  } else {
+    children = [props.leftChildren, props.rightChildren];
+  }
+  return <div>{children}</div>;
+}
+```
+
+The children will unmount and remount as you change the `swapped` prop because there aren't any keys marked on the two sets of children.
+
+To solve this problem, you can use the `createFragment` add-on to give keys to the sets of children.
+
+#### `Array<ReactNode> createFragment(object children)`
+
+Instead of creating arrays, we write:
+
+```javascript
+import createFragment from 'react-addons-create-fragment';
+
+function Swapper(props) {
+  let children;
+  if (props.swapped) {
+    children = createFragment({
+      right: props.rightChildren,
+      left: props.leftChildren
+    });
+  } else {
+    children = createFragment({
+      left: props.leftChildren,
+      right: props.rightChildren
+    });
+  }
+  return <div>{children}</div>;
+}
+```
+
+The keys of the passed object (that is, `left` and `right`) are used as keys for the entire set of children, and the order of the object's keys is used to determine the order of the rendered children. With this change, the two sets of children will be properly reordered in the DOM without unmounting.
+
+The return value of `createFragment` should be treated as an opaque object; you can use the [`React.Children`](https://facebook.github.io/react/docs/react-api.html#react.children) helpers to loop through a fragment but should not access it directly. Note also that we're relying on the JavaScript engine preserving object enumeration order here, which is not guaranteed by the spec but is implemented by all major browsers and VMs for objects with non-numeric keys.

+# react-addons-css-transition-group
+
+The code in this package has moved. We recommend you to use `CSSTransitionGroup` from [`react-transition-group`](https://github.com/reactjs/react-transition-group) instead.
+
+In particular, its version `1.x` is a drop-in replacement for the last released version of `react-addons-css-transition-group`.
+
+Run `npm install --save react-transition-group@1.x`, and replace the imports in your code:
+
+```js
+// Old
+import CSSTransitionGroup from 'react-addons-css-transition-group';
+
+// New
+import CSSTransitionGroup from 'react-transition-group/CSSTransitionGroup';
+```
+
+The documentation branch for `react-transition-group@1.x` [can be found here](https://github.com/reactjs/react-transition-group/tree/v1-stable#high-level-api-csstransitiongroup).

+# react-addons-linked-state-mixin
+
+>**Note:**
+>This is a legacy React addon, and is no longer maintained.
+>
+>We don't encourage using it in new code, but it exists for backwards compatibility.  
+>The recommended migration path is to explicitly set `value` and the `onChange` handler instead of using `LinkedStateMixin`.
+
+**Importing `LinkedStateMixin`**
+
+```javascript
+import LinkedStateMixin from 'react-addons-linked-state-mixin'; // ES6
+var LinkedStateMixin = require('react-addons-linked-state-mixin'); // ES5 with npm
+```
+
+If you prefer a `<script>` tag, you can get it from `React.addons.LinkedStateMixin` with:
+
+```html
+<!-- development version -->
+<script src="https://unpkg.com/react-addons-linked-state-mixin/react-addons-linked-state-mixin.js"></script>
+
+<!-- production version -->
+<script src="https://unpkg.com/react-addons-linked-state-mixin/react-addons-linked-state-mixin.min.js"></script>
+```
+
+In this case, make sure to put the `<script>` tag after React.
+
+**Importing `LinkedInput`**
+
+After React 16, you will also need `LinkedInput` component if you want to keep using this pattern. You can import it like this:
+
+```javascript
+import LinkedInput from 'react-linked-input'; // ES6
+var LinkedInput = require('react-linked-input'); // ES5 with npm
+```
+
+If you prefer a `<script>` tag, you can get it from `LinkedInput` global with:
+
+```html
+<!-- development version -->
+<script src="https://unpkg.com/react-linked-input/react-linked-input.js"></script>
+
+<!-- production version -->
+<script src="https://unpkg.com/react-linked-input/react-linked-input.min.js"></script>
+```
+
+## Overview
+
+`LinkedStateMixin` is an easy way to express two-way binding with React.
+
+In React, data flows one way: from owner to child. We think that this makes your app's code easier to understand. You can think of it as "one-way data binding."
+
+However, there are lots of applications that require you to read some data and flow it back into your program. For example, when developing forms, you'll often want to update some React `state` when you receive user input. Or perhaps you want to perform layout in JavaScript and react to changes in some DOM element size.
+
+In React, you would implement this by listening to a "change" event, read from your data source (usually the DOM) and call `setState()` on one of your components. "Closing the data flow loop" explicitly leads to more understandable and easier-to-maintain programs. See [our forms documentation](https://facebook.github.io/react/docs/forms.html) for more information.
+
+Two-way binding -- implicitly enforcing that some value in the DOM is always consistent with some React `state` -- is concise and supports a wide variety of applications. We've provided `LinkedStateMixin`: syntactic sugar for setting up the common data flow loop pattern described above, or "linking" some data source to React `state`.
+
+> Note:
+>
+> `LinkedStateMixin` is just a thin wrapper and convention around the `onChange`/`setState()` pattern. It doesn't fundamentally change how data flows in your React application.
+
+## LinkedStateMixin: Before and After
+
+Here's a simple form example without using `LinkedStateMixin`:
+
+```javascript
+var createReactClass = require('create-react-class');
+
+var NoLink = createReactClass({
+  getInitialState: function() {
+    return {message: 'Hello!'};
+  },
+  handleChange: function(event) {
+    this.setState({message: event.target.value});
+  },
+  render: function() {
+    var message = this.state.message;
+    return <input type="text" value={message} onChange={this.handleChange} />;
+  }
+});
+```
+
+This works really well and it's very clear how data is flowing, however, with a lot of form fields it could get a bit verbose. Let's use `LinkedStateMixin` to save us some typing:
+
+```javascript
+var createReactClass = require('create-react-class');
+var LinkedInput = require('react-linked-input');
+
+var WithLink = createReactClass({
+  mixins: [LinkedStateMixin],
+  getInitialState: function() {
+    return {message: 'Hello!'};
+  },
+  render: function() {
+    return <LinkedInput type="text" valueLink={this.linkState('message')} />;
+  }
+});
+```
+
+`LinkedStateMixin` adds a method to your React component called `linkState()`. `linkState()` returns a `valueLink` object which contains the current value of the React state and a callback to change it. The `LinkInput` component passes those properties to the input it renders.
+
+`valueLink` objects can be passed up and down the tree as props, so it's easy (and explicit) to set up two-way binding between a component deep in the hierarchy and state that lives higher in the hierarchy.
+
+Note that checkboxes have a special behavior regarding their `value` attribute, which is the value that will be sent on form submit if the checkbox is checked (defaults to `on`). The `value` attribute is not updated when the checkbox is checked or unchecked. For checkboxes, you should use `checkedLink` instead of `valueLink`:
+
+```
+<LinkedInput type="checkbox" checkedLink={this.linkState('booleanValue')} />
+```

+# react-addons-pure-render-mixin
+
+>**Note:**
+>This is a legacy React addon, and is no longer maintained.
+>
+>We don't encourage using it in new code, but it exists for backwards compatibility.  
+>The recommended migration path is to use [`React.PureComponent`](https://facebook.github.io/react/docs/react-api.html#react.purecomponent) instead.
+
+**Importing**
+
+```javascript
+import PureRenderMixin from 'react-addons-pure-render-mixin'; // ES6
+var PureRenderMixin = require('react-addons-pure-render-mixin'); // ES5 with npm
+```
+
+If you prefer a `<script>` tag, you can get it from `React.addons.PureRenderMixin` with:
+
+```html
+<!-- development version -->
+<script src="https://unpkg.com/react-addons-pure-render-mixin/react-addons-pure-render-mixin.js"></script>
+
+<!-- production version -->
+<script src="https://unpkg.com/react-addons-pure-render-mixin/react-addons-pure-render-mixin.min.js"></script>
+```
+
+In this case, make sure to put the `<script>` tag after React.
+
+## Overview
+
+If your React component's render function renders the same result given the same props and state, you can use this mixin for a performance boost in some cases.
+
+Example:
+
+```js
+const createReactClass = require('create-react-class');
+
+createReactClass({
+  mixins: [PureRenderMixin],
+
+  render: function() {
+    return <div className={this.props.className}>foo</div>;
+  }
+});
+```
+
+Under the hood, the mixin implements [shouldComponentUpdate](https://facebook.github.io/react/docs/component-specs.html#updating-shouldcomponentupdate), in which it compares the current props and state with the next ones and returns `false` if the equalities pass.
+
+> Note:
+>
+> This only shallowly compares the objects. If these contain complex data structures, it may produce false-negatives for deeper differences. Only mix into components which have simple props and state, or use `forceUpdate()` when you know deep data structures have changed. Or, consider using [immutable objects](https://facebook.github.io/immutable-js/) to facilitate fast comparisons of nested data.
+>
+> Furthermore, `shouldComponentUpdate` skips updates for the whole component subtree. Make sure all the children components are also "pure".

+If you prefer a `<script>` tag, you can get it from `React.addons.shallowCompare` with:
+
+```html
+<!-- development version -->
+<script src="https://unpkg.com/react-addons-shallow-compare/react-addons-shallow-compare.js"></script>
+
+<!-- production version -->
+<script src="https://unpkg.com/react-addons-shallow-compare/react-addons-shallow-compare.min.js"></script>
+```
+
+In this case, make sure to put the `<script>` tag after React.
+
+
+## Overview
+
+Before [`React.PureComponent`](https://facebook.github.io/react/docs/react-api.html#react.purecomponent) was introduced, `shallowCompare` was commonly used to achieve the same functionality as [`PureRenderMixin`](https://www.npmjs.com/package/react-addons-pure-render-mixin) while using ES6 classes with React.
+
+If your React component's render function is "pure" (in other words, it renders the same result given the same props and state), you can use this helper function for a performance boost in some cases.
+
+Example:
+
+```js
+export class SampleComponent extends React.Component {
+  shouldComponentUpdate(nextProps, nextState) {
+    return shallowCompare(this, nextProps, nextState);
+  }
+
+  render() {
+    return <div className={this.props.className}>foo</div>;
+  }
+}
+```
+
+`shallowCompare` performs a shallow equality check on the current `props` and `nextProps` objects as well as the current `state` and `nextState` objects.  
+It does this by iterating on the keys of the objects being compared and returning true when the values of a key in each object are not strictly equal.
+
+`shallowCompare` returns `true` if the shallow comparison for props or state fails and therefore the component should update.  
+`shallowCompare` returns `false` if the shallow comparison for props and state both pass and therefore the component does not need to update.

+# react-addons-transition-group
+
+The code in this package has moved. We recommend you to use `TransitionGroup` from [`react-transition-group`](https://github.com/reactjs/react-transition-group) instead.
+
+In particular, its version `1.x` is a drop-in replacement for the last released version of `react-addons-transition-group`.
+
+Run `npm install --save react-transition-group@1.x`, and replace the imports in your code:
+
+```js
+// Old
+import TransitionGroup from 'react-addons-transition-group';
+
+// New
+import TransitionGroup from 'react-transition-group/TransitionGroup';
+```
+
+The documentation branch for `react-transition-group@1.x` [can be found here](https://github.com/reactjs/react-transition-group/tree/v1-stable#low-level-api-transitiongroup).

+# react-addons-update
+
+>**Note:**
+>This is a legacy React addon, and is no longer maintained.
+>
+>We don't encourage using it in new code, but it exists for backwards compatibility.  
+>The recommended migration path is to use [`immutability-helper`](https://github.com/kolodny/immutability-helper). Its version `1.0.0` is a drop-in replacement.
+
+**Importing**
+
+```javascript
+import update from 'react-addons-update'; // ES6
+var update = require('react-addons-update'); // ES5 with npm
+```
+
+If you prefer a `<script>` tag, you can get it from `React.addons.update` with:
+
+```html
+<!-- development version -->
+<script src="https://unpkg.com/react-addons-update/react-addons-update.js"></script>
+
+<!-- production version -->
+<script src="https://unpkg.com/react-addons-update/react-addons-update.min.js"></script>
+```
+
+In this case, make sure to put the `<script>` tag after React.
+
+## Overview
+
+React lets you use whatever style of data management you want, including mutation. However, if you can use immutable data in performance-critical parts of your application it's easy to implement a fast [`shouldComponentUpdate()`](https://facebook.github.io/react/docs/react-component.html#shouldcomponentupdate) method to significantly speed up your app.
+
+Dealing with immutable data in JavaScript is more difficult than in languages designed for it, like [Clojure](http://clojure.org/). However, we've provided a simple immutability helper, `update()`, that makes dealing with this type of data much easier, *without* fundamentally changing how your data is represented. You can also take a look at Facebook's [Immutable-js](https://facebook.github.io/immutable-js/docs/) and the [Optimizing Performance](https://facebook.github.io/react/docs/optimizing-performance.html) section for more detail on Immutable-js.
+
+### The Main Idea
+
+If you mutate data like this:
+
+```js
+myData.x.y.z = 7;
+// or...
+myData.a.b.push(9);
+```
+
+You have no way of determining which data has changed since the previous copy has been overwritten. Instead, you need to create a new copy of `myData` and change only the parts of it that need to be changed. Then you can compare the old copy of `myData` with the new one in `shouldComponentUpdate()` using triple-equals:
+
+```js
+const newData = deepCopy(myData);
+newData.x.y.z = 7;
+newData.a.b.push(9);
+```
+
+Unfortunately, deep copies are expensive, and sometimes impossible. You can alleviate this by only copying objects that need to be changed and by reusing the objects that haven't changed. Unfortunately, in today's JavaScript this can be cumbersome:
+
+```js
+const newData = extend(myData, {
+  x: extend(myData.x, {
+    y: extend(myData.x.y, {z: 7}),
+  }),
+  a: extend(myData.a, {b: myData.a.b.concat(9)})
+});
+```
+
+While this is fairly performant (since it only makes a shallow copy of `log n` objects and reuses the rest), it's a big pain to write. Look at all the repetition! This is not only annoying, but also provides a large surface area for bugs.
+
+## `update()`
+
+`update()` provides simple syntactic sugar around this pattern to make writing this code easier. This code becomes:
+
+```js
+import update from 'react-addons-update';
+
+const newData = update(myData, {
+  x: {y: {z: {$set: 7}}},
+  a: {b: {$push: [9]}}
+});
+```
+
+While the syntax takes a little getting used to (though it's inspired by [MongoDB's query language](http://docs.mongodb.org/manual/core/crud-introduction/#query)) there's no redundancy, it's statically analyzable and it's not much more typing than the mutative version.
+
+The `$`-prefixed keys are called *commands*. The data structure they are "mutating" is called the *target*.
+
+## Available Commands
+
+  * `{$push: array}` `push()` all the items in `array` on the target.
+  * `{$unshift: array}` `unshift()` all the items in `array` on the target.
+  * `{$splice: array of arrays}` for each item in `arrays` call `splice()` on the target with the parameters provided by the item.
+  * `{$set: any}` replace the target entirely.
+  * `{$merge: object}` merge the keys of `object` with the target.
+  * `{$apply: function}` passes in the current value to the function and updates it with the new returned value.
+
+## Examples
+
+### Simple push
+
+```js
+const initialArray = [1, 2, 3];
+const newArray = update(initialArray, {$push: [4]}); // => [1, 2, 3, 4]
+```
+`initialArray` is still `[1, 2, 3]`.
+
+### Nested collections
+
+```js
+const collection = [1, 2, {a: [12, 17, 15]}];
+const newCollection = update(collection, {2: {a: {$splice: [[1, 1, 13, 14]]}}});
+// => [1, 2, {a: [12, 13, 14, 15]}]
+```
+This accesses `collection`'s index `2`, key `a`, and does a splice of one item starting from index `1` (to remove `17`) while inserting `13` and `14`.
+
+### Updating a value based on its current one
+
+```js
+const obj = {a: 5, b: 3};
+const newObj = update(obj, {b: {$apply: function(x) {return x * 2;}}});
+// => {a: 5, b: 6}
+// This is equivalent, but gets verbose for deeply nested collections:
+const newObj2 = update(obj, {b: {$set: obj.b * 2}});
+```
+
+### (Shallow) Merge
+
+```js
+const obj = {a: 5, b: 3};
+const newObj = update(obj, {$merge: {b: 6, c: 7}}); // => {a: 5, b: 6, c: 7}
+```

+# react-linked-input
+
+>**Note:**
+>This is a legacy React addon, and is no longer maintained.
+>
+>We don't encourage using it in new code, but it exists for backwards compatibility.  
+>The recommended migration path is to set `value` and `onChange` props directly instead of `valueLink` or `checkedLink`.
+
+This component supports the legacy `valueLink` API for `<input>` components. The built-in support for it is being removed from React. This component may be used as a migration plan (so your code doesn't break in React 16) or may be used if you just like the `valueLink` data binding semantics. However, this component is not maintained, so use at your own risk.
+
+For details on how to use it, refer to the [`LinkedStateMixin`](https://www.npmjs.com/package/react-addons-linked-state-mixin) documentation, since they usually appear together.
