 - **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).

([@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))

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.

+title: "React v15.5.0"
+author: acdlite
+---
+
+It's been exactly one year since the last breaking change to React. Our next major release, React 16, will include some exciting improvements, including a [complete rewrite](https://www.youtube.com/watch?v=ZCuYPiUIONs) of React's internals. [We take stability seriously](/react/contributing/design-principles.html#stability), and are committed to bringing those improvements to all of our users with minimal effort.
+
+To that end, today we're releasing React 15.5.0.
+
+### New Deprecation Warnings
+
+The biggest change is that we've extracted `React.PropTypes` and `React.createClass` into their own packages. Both are still accessible via the main `React` object, but using either will log a one-time deprecation warning to the console when in development mode. This will enable future code size optimizations.
+
+These warnings will not affect the behavior of your application. However, we realize they may cause some frustration, particularly if you use a testing framework that treats `console.error` as a failure.
+
+**Adding new warnings is not something we do lightly.** Warnings in React are not mere suggestions — they are integral to our strategy of keeping as many people as possible on the latest version of React. We never add warnings without providing an incremental path forward.
+
+So while the warnings may cause frustration in the short-term, we believe **prodding developers to migrate their codebases now prevents greater frustration in the future**. Proactively fixing warnings ensures you are prepared for the next major release. If your app produces zero warnings in 15.5, it should continue to work in 16 without any changes.
+
+For each of these new deprecations, we've provided a codemod to automatically migrate your code. They are available as part of the [react-codemod](https://github.com/reactjs/react-codemod) project.
+
+### Migrating from React.PropTypes
+
+Prop types are a feature for runtime validation of props during development. We've extracted the built-in prop types to a separate package to reflect the fact that not everybody uses them.
+
+In 15.5, instead of accessing `PropTypes` from the main `React` object, install the `prop-types` package and import them from there:
+
+```js{11,16,25}
+// Before (15.4 and below)
+import React from 'react';
+
+class Component extends React.Component {
+  render() {
+    return <div>{this.props.text}</div>;
+  }
+}
+
+Component.propTypes = {
+  text: React.PropTypes.string.isRequired,
+}
+
+// After (15.5)
+import React from 'react';
+import PropTypes from 'prop-types';
+
+class Component extends React.Component {
+  render() {
+    return <div>{this.props.text}</div>;
+  }
+}
+
+Component.propTypes = {
+  text: PropTypes.string.isRequired,
+};
+```
+
+The [codemod](https://github.com/reactjs/react-codemod#react-proptypes-to-prop-types) for this change performs this conversion automatically. Basic usage:
+
+```bash
+jscodeshift -t react-codemod/transforms/React-PropTypes-to-prop-types.js <path>
+```
+
+
+The `propTypes`, `contextTypes`, and `childContextTypes` APIs will work exactly as before. The only change is that the built-in validators now live in a separate package.
+
+You may also consider using [Flow](https://flow.org/) to statically type check your JavaScript code, including [React components](https://flow.org/en/docs/frameworks/react/#setup-flow-with-react-a-classtoc-idtoc-setup-flow-with-react-hreftoc-setup-flow-with-reacta).
+
+### Migrating from React.createClass
+
+When React was initially released, there was no idiomatic way to create classes in JavaScript, so we provided our own: `React.createClass`.
+
+Later, classes were added to the language as part of ES2015, so we added the ability to create React components using JavaScript classes. **Along with functional components, JavaScript classes are now the [preferred way to create components in React](/react/docs/components-and-props.html#functional-and-class-components).**
+
+For your existing `createClass` components, we recommend that you migrate them to JavaScript classes. However, if you have components that rely on mixins, converting to classes may not be immediately feasible. If so, `create-react-class` is available on npm as a drop-in replacement:
+
+```js{4,13,15}
+// Before (15.4 and below)
+var React = require('react');
+
+var Component = React.createClass({
+  mixins: [MixinA],
+  render() {
+    return <Child />;
+  }
+});
+
+// After (15.5)
+var React = require('react');
+var createReactClass = require('create-react-class');
+
+var Component = createReactClass({
+  mixins: [MixinA],
+  render() {
+    return <Child />;
+  }
+});
+```
+
+Your components will continue to work the same as they did before.
+
+The [codemod](https://github.com/reactjs/react-codemod#explanation-of-the-new-es2015-class-transform-with-property-initializers) for this change attempts to convert a `createClass` component to a JavaScript class, with a fallback to `create-react-class` if necessary. It has converted thousands of components internally at Facebook.
+
+Basic usage:
+
+```bash
+jscodeshift -t react-codemod/transforms/class.js path/to/components
+```
+
+### Discontinuing support for React Addons
+
+We're discontinuing active maintenance of React Addons packages. In truth, most of these packages haven't been actively maintained in a long time. They will continue to work indefinitely, but we recommend migrating away as soon as you can to prevent future breakages.
+
+- **react-addons-create-fragment** – React 16 will have first-class support for fragments, at which point this package won't be necessary. We recommend using arrays of keyed elements instead.
+- **react-addons-css-transition-group** - Use [react-transition-group/CSSTransitionGroup](https://github.com/reactjs/react-transition-group) instead. Version 1.1.1 provides a drop-in replacement.
+- **react-addons-linked-state-mixin** - Explicitly set the `value` and `onChange` handler instead.
+- **react-addons-pure-render-mixin** - Use [`React.PureComponent`](/react/docs/react-api.html#react.purecomponent) instead.
+- **react-addons-shallow-compare** - Use [`React.PureComponent`](/react/docs/react-api.html#react.purecomponent) instead.
+- **react-addons-transition-group** - Use [react-transition-group/TransitionGroup](https://github.com/reactjs/react-transition-group) instead. Version 1.1.1 provides a drop-in replacement.
+- **react-addons-update** - Use [immutability-helper](https://github.com/kolodny/immutability-helper) instead, a drop-in replacement.
+- **react-linked-input** - Explicitly set the `value` and `onChange` handler instead.
+
+We're also discontinuing support for the `react-with-addons` UMD build. It will be removed in React 16.
+
+### React Test Utils
+
+Currently, the React Test Utils live inside `react-addons-test-utils`. As of 15.5, we're deprecating that package and moving them to `react-dom/test-utils` instead:
+
+```js
+// Before (15.4 and below)
+import TestUtils from 'react-addons-test-utils';
+
+// After (15.5)
+import TestUtils from 'react-dom/test-utils';
+```
+
+This reflects the fact that what we call the Test Utils are really a set of APIs that wrap the DOM renderer.
+
+The exception is shallow rendering, which is not DOM-specific. The shallow renderer has been moved to `react-test-renderer/shallow`.
+
+```js{2,5}
+// Before (15.4 and below)
+import { createRenderer } from 'react-addons-test-utils';
+
+// After (15.5)
+import { createRenderer } from 'react-test-renderer/shallow';
+```

+
+## Installation
+
+We recommend using [Yarn](https://yarnpkg.com/) or [npm](https://www.npmjs.com/) for managing front-end dependencies. If you're new to package managers, the [Yarn documentation](https://yarnpkg.com/en/docs/getting-started) is a good place to get started.
+
+To install React with Yarn, run:
+
+```bash
+yarn add react@15.5.0 react-dom@15.5.0
+```
+
+To install React with npm, run:
+
+```bash
+npm install --save react@15.5.0 react-dom@15.5.0
+```
+
+We recommend using a bundler like [webpack](https://webpack.js.org/) or [Browserify](http://browserify.org/) so you can write modular code and bundle it together into small packages to optimize load time.
+
+Remember that by default, React runs extra checks and provides helpful warnings in development mode. When deploying your app, make sure to [compile it in production mode](/react/docs/installation.html#development-and-production-versions).
+
+In case you don't use a bundler, we also provide pre-built bundles in the npm packages which you can [include as script tags](/react/docs/installation.html#using-a-cdn) on your page:
