15.0.1 (April 8, 2016)

React

  • Restore React.__spread API to unbreak code compiled with some tools making use of this undocumented API. It is now officially deprecated. (@zpao in #6444)

ReactDOM

  • Fixed issue resulting in loss of cursor position in controlled inputs. (@spicyj in #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 in #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 in #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 in #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 in #5451)
  • Functional components can now return null. We added support for defining stateless components as functions 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, 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 in #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. (@zpao in #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 in #5997)
  • ReactPerf.getLastMeasurements() is opaque. This change won’t affect applications but may break some third-party tools. We are revamping ReactPerf implementation 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 in #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 in #5832)
  • Deprecated addons are removed: batchedUpdates and cloneWithProps. (@jimfb in #5859, @zpao in #6016)
  • Deprecated component instance methods are removed: setProps, replaceProps, and getDOMNode. (@jimfb in #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 in #6285)
  • Passing children to void elements like <input> was deprecated, and now throws an error. (@jonhester in #3372)
  • React-specific properties on DOM refs (e.g. this.refs.div.props) were deprecated, and are removed now. (@jimfb in #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. (@jimfb in #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 in #5048)
  • ReactPerf.printDOM() was renamed to ReactPerf.printOperations(), and ReactPerf.getMeasurementsSummaryMap() was renamed to ReactPerf.getWasted(). (@gaearon in #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 in #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 in #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 in #5940 and @koba04 in #5947)
  • Elements will now warn when attempting to read ref and key from the props. (@prometheansacrifice in #5744)
  • React will now warn if you pass a different props object to super() in the constructor. (@prometheansacrifice in #5346)
  • React will now warn if you call setState() inside getChildContext(). (@raineroviir in #6121)
  • React DOM now attempts to warn for mistyped event handlers on DOM elements, such as onclick which should be onClick. (@ali in #5361)
  • React DOM now warns about NaN values in style. (@jontewks in #5811)
  • React DOM now warns if you specify both value and defaultValue for an input. (@mgmcdermott in #5823)
  • React DOM now warns if an input switches between being controlled and uncontrolled. (@TheBlasfem in #5864)
  • React DOM now warns if you specify onFocusIn or onFocusOut handlers as they are unnecessary in React. (@jontewks in #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 in #5193 and @gaearon in #6310)
  • Add-Ons: TestUtils.Simulate() now prints a helpful message if you attempt to use it with shallow rendering. (@conorhastings in #5358)
  • PropTypes: arrayOf() and objectOf() provide better error messages for invalid arguments. (@chicoxyzzy in #5390)

Notable bug fixes

  • Fixed multiple small memory leaks. (@spicyj in #4983 and @victor-homyakov in #6309)
  • Input events are handled more reliably in IE 10 and IE 11; spurious events no longer fire when using a placeholder. (@jquense in #4051)
  • The componentWillReceiveProps() lifecycle method is now consistently called when context changes. (@milesj in #5787)
  • React.cloneElement() doesn’t append slash to an existing key when used inside React.Children.map(). (@ianobermiller in #5892)
  • React DOM now supports the cite and profile HTML attributes. (@AprilArcus in #6094 and @saiichihashimoto in #6032)
  • React DOM now supports cssFloat, gridRow and gridColumn CSS properties. (@stevenvachon in #6133 and @mnordick in #4779)
  • React DOM now correctly handles borderImageOutset, borderImageWidth, borderImageSlice, floodOpacity, strokeDasharray, and strokeMiterlimit as unitless CSS properties. (@rofrischmann in #6210 and #6270)
  • React DOM now supports the onAnimationStart, onAnimationEnd, onAnimationIteration, onTransitionEnd, and onInvalid events. Support for onLoad has been added to object elements. (@tomduncalf in #5187, @milesj in #6005, and @ara4n in #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 in #1510)
  • React DOM does not mistakingly coerce children to strings for Web Components. (@jimfb in #5093)
  • React DOM now correctly normalizes SVG <use> events. (@edmellum in #5720)
  • React DOM does not throw if a <select> is unmounted while its onChange handler is executing. (@sambev in #6028)
  • React DOM does not throw in Windows 8 apps. (@Andrew8xx8 in #6063)
  • React DOM does not throw when asynchronously unmounting a child with a ref. (@yiminghe in #6095)
  • React DOM no longer forces synchronous layout because of scroll position tracking. (@syranide in #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 in #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 in #5209)

### Other improvements

  • React now uses loose-envify instead of envify so it installs fewer transitive dependencies. (@qerub in #6303)
  • Shallow renderer now exposes getMountedInstance(). (@glenjamin in #4918)
  • Shallow renderer now returns the rendered output from render(). (@simonewebdesign in #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 in #4959)
  • React DOM now allows data- attributes with names that start with numbers. (@nLight in #5216)
  • React DOM adds a new suppressContentEditableWarning prop for components like Draft.js that intentionally manage contentEditable children with React. (@mxstbr in #6112)
  • React improves the performance for createClass() on complex specs. (@spicyj in #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 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.

0.13.3 (May 8, 2015)

React Core

New Features

  • Added clipPath element and attribute for SVG
  • Improved warnings for deprecated methods in plain JS classes

Bug Fixes

  • Loosened dangerouslySetInnerHTML restrictions so {__html: undefined} will no longer throw
  • Fixed extraneous context warning with non-pure getChildContext
  • Ensure replaceState(obj) retains prototype of obj

React with Add-ons

Bug Fixes

  • Test Utils: Ensure that shallow rendering works when components define contextTypes

0.13.2 (April 18, 2015)

React Core

New Features

  • Added strokeDashoffset, flexPositive, flexNegative to the list of unitless CSS properties
  • Added support for more DOM properties:
    • scoped - for <style> elements
    • high, low, optimum - for <meter> elements
    • unselectable - IE-specific property to prevent user selection

Bug Fixes

  • Fixed a case where re-rendering after rendering null didn't properly pass context
  • Fixed a case where re-rendering after rendering with style={null} didn't properly update style
  • Update uglify dependency to prevent a bug in IE8
  • Improved warnings

React with Add-Ons

Bug Fixes

  • Immutability Helpers: Ensure it supports hasOwnProperty as an object key

0.13.1 (March 16, 2015)

React Core

Bug Fixes

  • Don't throw when rendering empty <select> elements
  • Ensure updating style works when transitioning from null

React with Add-Ons

Bug Fixes

  • TestUtils: Don't warn about getDOMNode for ES6 classes
  • TestUtils: Ensure wrapped full page components (<html>, <head>, <body>) are treated as DOM components
  • Perf: Stop double-counting DOM components

React Tools

Bug Fixes

  • Fix option parsing for --non-strict-es6module

0.13.0 (March 10, 2015)

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

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.

0.12.2 (December 18, 2014)

React Core

  • Added support for more HTML attributes: formAction, formEncType, formMethod, formTarget, marginHeight, marginWidth
  • Added strokeOpacity to the list of unitless CSS properties
  • Removed trailing commas (allows npm module to be bundled and used in IE8)
  • Fixed bug resulting in error when passing undefined to React.createElement - now there is a useful warning

React Tools

  • JSX-related transforms now always use double quotes for props and displayName

0.12.1 (November 18, 2014)

React Tools

  • Types transform updated with latest support
  • jstransform version updated with improved ES6 transforms
  • Explicit Esprima dependency removed in favor of using Esprima information exported by jstransform

0.12.0 (October 28, 2014)

React Core

Breaking Changes

  • key and ref moved off props object, now accessible on the element directly
  • React is now BSD licensed with accompanying Patents grant
  • Default prop resolution has moved to Element creation time instead of mount time, making them effectively static
  • React.__internals is removed - it was exposed for DevTools which no longer needs access
  • Composite Component functions can no longer be called directly - they must be wrapped with React.createFactory first. This is handled for you when using JSX.

New Features

  • Spread operator ({...}) introduced to deprecate this.transferPropsTo
  • Added support for more HTML attributes: acceptCharset, classID, manifest

Deprecations

  • React.renderComponent --> React.render

    • scrollLeft, scrollTop removed, these should not be specified as props
  • Improved error messages

React With Addons

New Features

  • React.addons.batchedUpdates added to API for hooking into update cycle

Breaking Changes

  • React.addons.update uses assign instead of copyProperties which does hasOwnProperty checks. Properties on prototypes will no longer be updated correctly.

Bug Fixes

  • Fixed some issues with CSS Transitions

JSX

Breaking Changes

  • Enforced convention: lower case tag names are always treated as HTML tags, upper case tag names are always treated as composite components
  • JSX no longer transforms to simple function calls

New Features

  • @jsx React.DOM no longer required
  • spread ({...}) operator introduced to allow easier use of props

Bug Fixes

  • JSXTransformer: Make sourcemaps an option when using APIs directly (eg, for react-rails)

JSX

  • Fix duplicate variable declaration in JSXTransformer (caused issues in some browsers)

0.11.0 (July 17, 2014)

React Core

Breaking Changes

  • getDefaultProps() is now called once per class and shared across all instances
  • MyComponent() now returns a descriptor, not an instance
  • React.isValidComponent and React.PropTypes.component validate descriptors, not component instances
  • Custom propType validators should return an Error instead of logging directly

New Features

  • Rendering to null
  • Keyboard events include normalized e.key and e.getModifierState() properties
  • New normalized onBeforeInput event
  • React.Children.count has been added as a helper for counting the number of children

Bug Fixes

React With Addons

  • PureRenderMixin: a mixin which helps optimize "pure" components
  • Perf: a new set of tools to help with performance analysis
  • Update: New $apply command to transform values
  • TransitionGroup bug fixes with null elements, Android

React NPM Module

  • Now includes the pre-built packages under dist/.
  • envify is properly listed as a dependency instead of a peer dependency

JSX

  • Added support for namespaces, eg <Components.Checkbox />
  • JSXTransformer
    • Enable the same harmony features available in the command line with <script type="text/jsx;harmony=true">
    • Scripts are downloaded in parallel for more speed. They are still executed in order (as you would expect with normal script tags)
    • Fixed a bug preventing sourcemaps from working in Firefox

React Tools Module

  • Improved readme with usage and API information
  • Improved ES6 transforms available with --harmony option
  • Added --source-map-inline option to the jsx executable

0.10.0 (March 21, 2014)

React Core

New Features

  • Added warnings to help migrate towards descriptors
  • Made it possible to server render without React-related markup (data-reactid, data-react-checksum). This DOM will not be mountable by React. Read the docs for React.renderComponentToStaticMarkup
  • Added support for more attributes:
    • srcSet for <img> to specify images at different pixel ratios
    • textAnchor for SVG

Bug Fixes

  • Ensure all void elements don’t insert a closing tag into the markup.
  • Ensure className={false} behaves consistently
  • Ensure this.refs is defined, even if no refs are specified.

Addons

react-tools

  • Added an option argument to transform function. The only option supported is harmony, which behaves the same as jsx --harmony on the command line. This uses the ES6 transforms from jstransform.

0.9.0 (February 20, 2014)

React Core

Breaking Changes

  • The lifecycle methods componentDidMount and componentDidUpdate no longer receive the root node as a parameter; use this.getDOMNode() instead

  • On mouse wheel events, deltaY is no longer negated
  • When prop types validation fails, a warning is logged instead of an error thrown (with the production build of React, type checks are now skipped for performance)
  • On input, select, and textarea elements, .getValue() is no longer supported; use .getDOMNode().value instead
  • this.context on components is now reserved for internal use by React

New Features

  • Added support for onReset on <form> elements
  • The autoFocus attribute is now polyfilled consistently on input, select, and textarea

Bug Fixes

  • React no longer adds an __owner__ property to each component's props object; passed-in props are now never mutated
  • When nesting top-level components (e.g., calling React.renderComponent within componentDidMount), events now properly bubble to the parent component
  • Fixed a case where nesting top-level components would throw an error when updating
  • Passing an invalid or misspelled propTypes type now throws an error
  • On mouse enter/leave events, .target, .relatedTarget, and .type are now set properly

  • Fixed bug with selection and focus.
  • Made it possible to unmount components from the document root.
  • Fixed bug for disabled attribute handling on non-<input> elements.

React with Addons

  • Fixed bug with transition and animation event detection.

0.5.0 (October 16, 2013)

React

  • Memory usage improvements - reduced allocations in core which will help with GC pauses
  • Performance improvements - in addition to speeding things up, we made some tweaks to stay out of slow path code in V8 and Nitro.
  • Standardized prop -> DOM attribute process. This previously resulting in additional type checking and overhead as well as confusing cases for users. Now we will always convert your value to a string before inserting it into the DOM.
  • Support for Selection events.
  • Support for Composition events.
  • Support for additional DOM properties (charSet, content, form, httpEquiv, rowSpan, autoCapitalize).
  • Support for additional SVG properties (rx, ry).
  • Support for using getInitialState and getDefaultProps in mixins.
  • Support mounting into iframes.
  • Bug fixes for controlled form components.
  • Bug fixes for SVG element creation.
  • Added React.version.
  • Added React.isValidClass - Used to determine if a value is a valid component constructor.
  • Removed React.autoBind - This was deprecated in v0.4 and now properly removed.
  • Renamed React.unmountAndReleaseReactRootNode to React.unmountComponentAtNode.
  • Began laying down work for refined performance analysis.
  • Better support for server-side rendering - react-page has helped improve the stability for server-side rendering.
  • Made it possible to use React in environments enforcing a strict Content Security Policy. This also makes it possible to use React to build Chrome extensions.

React with Addons (New!)

  • Introduced a separate build with several "addons" which we think can help improve the React experience. We plan to deprecate this in the long-term, instead shipping each as standalone pieces. Read more in the docs.

JSX

  • No longer transform class to className as part of the transform! This is a breaking change - if you were using class, you must change this to className or your components will be visually broken.
  • Added warnings to the in-browser transformer to make it clear it is not intended for production use.
  • Improved compatibility for Windows
  • Improved support for maintaining line numbers when transforming.

0.4.1 (July 26, 2013)

React

  • setState callbacks are now executed in the scope of your component.
  • click events now work on Mobile Safari.
  • Prevent a potential error in event handling if Object.prototype is extended.
  • Don't set DOM attributes to the string "undefined" on update when previously defined.
  • Improved support for <iframe> attributes.
  • Added checksums to detect and correct cases where server-side rendering markup mismatches what React expects client-side.

JSXTransformer

  • Improved environment detection so it can be run in a non-browser environment.

0.4.0 (July 17, 2013)

React

  • Switch from using id attribute to data-reactid to track DOM nodes. This allows you to integrate with other JS and CSS libraries more easily.
  • Support for more DOM elements and attributes (e.g., <canvas>)
  • Improved server-side rendering APIs. React.renderComponentToString(<component>, callback) allows you to use React on the server and generate markup which can be sent down to the browser.
  • prop improvements: validation and default values. Read our blog post for details...
  • Support for the key prop, which allows for finer control over reconciliation. Read the docs for details...
  • Removed React.autoBind. Read our blog post for details...
  • Improvements to forms. We've written wrappers around <input>, <textarea>, <option>, and <select> in order to standardize many inconsistencies in browser implementations. This includes support for defaultValue, and improved implementation of the onChange event, and circuit completion. Read the docs for details...
  • We've implemented an improved synthetic event system that conforms to the W3C spec.
  • Updates to your component are batched now, which may result in a significantly faster re-render of components. this.setState now takes an optional callback as it's second parameter. If you were using onClick={this.setState.bind(this, state)} previously, you'll want to make sure you add a third parameter so that the event is not treated as the callback.

JSX

  • Support for comment nodes <div>{/* this is a comment and won't be rendered */}</div>
  • Children are now transformed directly into arguments instead of being wrapped in an array E.g. <div><Component1/><Component2/></div> is transformed into React.DOM.div(null, Component1(null), Component2(null)). Previously this would be transformed into React.DOM.div(null, [Component1(null), Component2(null)]). If you were using React without JSX previously, your code should still work.

react-tools

  • Fixed a number of bugs when transforming directories
  • No longer re-write require()s to be relative unless specified

0.3.3 (June 20, 2013)

React

  • Allow reusing the same DOM node to render different components. e.g. React.renderComponent(<div/>, domNode); React.renderComponent(<span/>, domNode); will work now.

JSX

  • Improved the in-browser transformer so that transformed scripts will execute in the expected scope. The allows components to be defined and used from separate files.

react-tools

  • Upgrade Commoner so require statements are no longer relativized when passing through the transformer. This was a feature needed when building React, but doesn't translate well for other consumers of bin/jsx.
  • Upgraded our dependencies on Commoner and Recast so they use a different directory for their cache.
  • Freeze our Esprima dependency.

0.3.2 (May 31, 2013)

JSX

  • Improved compatibility with other coding styles (specifically, multiple assignments with a single var).

react-tools

  • Switch from using the browserified build to shipping individual modules. This allows react-tools to be used with browserify.

0.3.1 (May 30, 2013)

react-tools

  • Fix bug in packaging resulting in broken module.

0.3.0 (May 29, 2013)

  • Initial public release
