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 where a user defines a single stateless render function (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 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 helper to migrate, which now returns an array.
• Add-Ons: classSet has been removed. Use 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 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 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. 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 with a specific ES2015 (ES6) Symbol 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.
• 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 add-on has been added as a migration path for PureRenderMixin in ES6 classes.
• Add-Ons: CSSTransitionGroup can now use custom class names 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. You can continue using version 0.13.3 of both, but we no longer support them and recommend migrating to Babel, 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.

v0.13.0

Compare Source

React Core

Breaking Changes

• Deprecated patterns that warned in 0.12 no longer work: most prominently, calling component classes without using JSX or React.createElement and using non-component functions with JSX or createElement
• Mutating props after an element is created is deprecated and will cause warnings in development mode; future versions of React will incorporate performance optimizations assuming that props aren't mutated
• Static methods (defined in statics) are no longer autobound to the component class
• ref resolution order has changed slightly such that a ref to a component is available immediately after its componentDidMount method is called; this change should be observable only if your component calls a parent component's callback within your componentDidMount, which is an anti-pattern and should be avoided regardless
• Calls to setState in life-cycle methods are now always batched and therefore asynchronous. Previously the first call on the first mount was synchronous.
• setState and forceUpdate on an unmounted component now warns instead of throwing. That avoids a possible race condition with Promises.
• Access to most internal properties has been completely removed, including this._pendingState and this._rootNodeID.

New Features

• Support for using ES6 classes to build React components; see the v0.13.0 beta 1 notes for details.
• Added new top-level API React.findDOMNode(component), which should be used in place of component.getDOMNode(). The base class for ES6-based components will not have getDOMNode. This change will enable some more patterns moving forward.
• Added a new top-level API React.cloneElement(el, props) for making copies of React elements – see the v0.13 RC2 notes for more details.
• New ref style, allowing a callback to be used in place of a name: <Photo ref={(c) => this._photo = c} /> allows you to reference the component with this._photo (as opposed to ref="photo" which gives this.refs.photo).
• this.setState() can now take a function as the first argument for transactional state updates, such as this.setState((state, props) => ({count: state.count + 1})); – this means that you no longer need to use this._pendingState, which is now gone.
• Support for iterators and immutable-js sequences as children.

Deprecations

• ComponentClass.type is deprecated. Just use ComponentClass (usually as element.type === ComponentClass).
• Some methods that are available on createClass-based components are removed or deprecated from ES6 classes (getDOMNode, replaceState, isMounted, setProps, replaceProps).

React with Add-Ons

New Features

• React.addons.createFragment was added for adding keys to entire sets of children.

Deprecations

• React.addons.classSet is now deprecated. This functionality can be replaced with several freely available modules. classnames is one such module.
• Calls to React.addons.cloneWithProps can be migrated to use React.cloneElement instead – make sure to merge style and className manually if desired.

React Tools

Breaking Changes

• When transforming ES6 syntax, class methods are no longer enumerable by default, which requires Object.defineProperty; if you support browsers such as IE8, you can pass --target es3 to mirror the old behavior

New Features

• --target option is available on the jsx command, allowing users to specify and ECMAScript version to target.
  • es5 is the default.
  • es3 restores the previous default behavior. An additional transform is added here to ensure the use of reserved words as properties is safe (eg this.static will become this['static'] for IE8 compatibility).
• The transform for the call spread operator has also been enabled.

JSXTransformer

Breaking Changes

• The return value of transform now contains sourceMap as a JS object already, not an instance of SourceMapGenerator.

JSX

Breaking Changes

• A change was made to how some JSX was parsed, specifically around the use of > or } when inside an element. Previously it would be treated as a string but now it will be treated as a parse error. The jsx_orphaned_brackets_transformer package on npm can be used to find and fix potential issues in your JSX code.
