-## 16.0.0 (September 26, 2017)
-
-### New JS Environment Requirements
-
- * React 16 depends on the collection types [Map](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Map) and [Set](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Set), as well as [requestAnimationFrame](https://developer.mozilla.org/en-US/docs/Web/API/window/requestAnimationFrame). If you support older browsers and devices which may not yet provide these natively (e.g. <IE11), [you may want to include a polyfill](https://gist.github.com/gaearon/9a4d54653ae9c50af6c54b4e0e56b583).
-
-### New Features
-* Components can now return arrays and strings from `render`. (Docs coming soon!)
-* Improved error handling with introduction of "error boundaries". [Error boundaries](https://facebook.github.io/react/blog/2017/07/26/error-handling-in-react-16.html) are React components that catch JavaScript errors anywhere in their child component tree, log those errors, and display a fallback UI instead of the component tree that crashed.
-* First-class support for declaratively rendering a subtree into another DOM node with `ReactDOM.createPortal()`. (Docs coming soon!)
-* Streaming mode for server side rendering is enabled with `ReactDOMServer.renderToNodeStream()` and `ReactDOMServer.renderToStaticNodeStream()`. ([@aickin](https://github.com/aickin) in [#10425](https://github.com/facebook/react/pull/10425), [#10044](https://github.com/facebook/react/pull/10044), [#10039](https://github.com/facebook/react/pull/10039), [#10024](https://github.com/facebook/react/pull/10024), [#9264](https://github.com/facebook/react/pull/9264), and others.)
-* [React DOM now allows passing non-standard attributes](https://facebook.github.io/react/blog/2017/09/08/dom-attributes-in-react-16.html). ([@nhunzaker](https://github.com/nhunzaker) in [#10385](https://github.com/facebook/react/pull/10385), [10564](https://github.com/facebook/react/pull/10564), [#10495](https://github.com/facebook/react/pull/10495) and others)
-
-### Breaking Changes
-- There are several changes to the behavior of scheduling and lifecycle methods:
-  * `ReactDOM.render()` and `ReactDOM.unstable_renderIntoContainer()` now return `null` if called from inside a lifecycle method.
-    * To work around this, you can either use [the new portal API](https://github.com/facebook/react/issues/10309#issuecomment-318433235) or [refs](https://github.com/facebook/react/issues/10309#issuecomment-318434635).
-  * Minor changes to `setState` behavior:
-    * Calling `setState` with null no longer triggers an update. This allows you to decide in an updater function if you want to re-render.
-    * Calling `setState` directly in render always causes an update. This was not previously the case. Regardless, you should not be calling `setState` from render.
-    * `setState` callback (second argument) now fires immediately after `componentDidMount` / `componentDidUpdate` instead of after all components have rendered.
-  * When replacing `<A />` with `<B />`,  `B.componentWillMount` now always happens before  `A.componentWillUnmount`. Previously, `A.componentWillUnmount` could fire first in some cases.
-  * Previously, changing the `ref` to a component would always detach the ref before that component's render is called. Now, we change the `ref` later, when applying the changes to the DOM.
-  * It is not safe to re-render into a container that was modified by something other than React. This worked previously in some cases but was never supported. We now emit a warning in this case. Instead you should clean up your component trees using `ReactDOM.unmountComponentAtNode`. [See this example.](https://github.com/facebook/react/issues/10294#issuecomment-318820987)
-  * `componentDidUpdate` lifecycle no longer receives `prevContext` param. ([@bvaughn](https://github.com/bvaughn) in [#8631](https://github.com/facebook/react/pull/8631))
-  * Non-unique keys may now cause children to be duplicated and/or omitted. Using non-unique keys is not (and has never been) supported, but previously it was a hard error.
-  * Shallow renderer no longer calls `componentDidUpdate()` because DOM refs are not available. This also makes it consistent with `componentDidMount()` (which does not get called in previous versions either).
-  * Shallow renderer does not implement `unstable_batchedUpdates()` anymore.
-- The names and paths to the single-file browser builds have changed to emphasize the difference between development and production builds. For example:
-  - `react/dist/react.js` → `react/umd/react.development.js`
-  - `react/dist/react.min.js` → `react/umd/react.production.min.js`
-  - `react-dom/dist/react-dom.js` → `react-dom/umd/react-dom.development.js`
-  - `react-dom/dist/react-dom.min.js` → `react-dom/umd/react-dom.production.min.js`
-* The server renderer has been completely rewritten, with some improvements:
-  * Server rendering does not use markup validation anymore, and instead tries its best to attach to existing DOM, warning about inconsistencies. It also doesn't use comments for empty components and data-reactid attributes on each node anymore.
-  * Hydrating a server rendered container now has an explicit API. Use `ReactDOM.hydrate` instead of `ReactDOM.render` if you're reviving server rendered HTML. Keep using `ReactDOM.render` if you're just doing client-side rendering.
-* When "unknown" props are passed to DOM components, for valid values, React will now render them in the DOM. [See this post for more details.](https://facebook.github.io/react/blog/2017/09/08/dom-attributes-in-react-16.html) ([@nhunzaker](https://github.com/nhunzaker) in [#10385](https://github.com/facebook/react/pull/10385), [10564](https://github.com/facebook/react/pull/10564), [#10495](https://github.com/facebook/react/pull/10495) and others)
-* Errors in the render and lifecycle methods now unmount the component tree by default. To prevent this, add [error boundaries](https://facebook.github.io/react/blog/2017/07/26/error-handling-in-react-16.html) to the appropriate places in the UI.
-
-### Removed Deprecations
-
-- There is no `react-with-addons.js` build anymore. All compatible addons are published separately on npm, and have single-file browser versions if you need them.
-- The deprecations introduced in 15.x have been removed from the core package. `React.createClass` is now available as create-react-class, `React.PropTypes` as prop-types, `React.DOM` as react-dom-factories, react-addons-test-utils as react-dom/test-utils, and shallow renderer as react-test-renderer/shallow. See [15.5.0](https://facebook.github.io/react/blog/2017/04/07/react-v15.5.0.html) and [15.6.0](https://facebook.github.io/react/blog/2017/06/13/react-v15.6.0.html) blog posts for instructions on migrating code and automated codemods.

 ## 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. ([@sophiebits](https://github.com/sophiebits) 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`. ([@sophiebits](https://github.com/sophiebits) in [#5205](https://github.com/facebook/react/pull/5205))

([@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. ([@sophiebits](https://github.com/sophiebits) 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).

+>**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".

+# react-addons-shallow-compare
+
+>**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 shallowCompare from 'react-addons-shallow-compare'; // ES6
+var shallowCompare = require('react-addons-shallow-compare'); // ES5 with npm
+```
+
+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}
+```

+
+>**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.
