- Changing
- CSS property names with vendor prefixes (
Webkit,ms,Moz,O) are now handled properly - Duplicate keys no longer cause a hard error; now a warning is logged (and only one of the children with the same key is shown)
imgevent listeners are now unbound properly, preventing the error "Two valid but unequal nodes with the samedata-reactid"- Added explicit warning when missing polyfills

srcSetfor<img>to specify images at different pixel ratiostextAnchorfor SVG
- Ensure all void elements don’t insert a closing tag into the markup.
- Ensure
className={false}behaves consistently - Ensure
this.refsis defined, even if no refs are specified.
updatefunction to deal with immutable data. Read the docs
- Added an option argument to
transformfunction. The only option supported isharmony, which behaves the same asjsx --harmonyon the command line. This uses the ES6 transforms from jstransform.
- The lifecycle methods
componentDidMountandcomponentDidUpdateno longer receive the root node as a parameter; usethis.getDOMNode()instead - Whenever a prop is equal to
undefined, the default value returned bygetDefaultPropswill now be used instead React.unmountAndReleaseReactRootNodewas previously deprecated and has now been removedReact.renderComponentToStringis now synchronous and returns the generated HTML string- Full-page rendering (that is, rendering the
<html>tag using React) is now supported only when starting with server-rendered markup - On mouse wheel events,
deltaYis 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, andtextareaelements,.getValue()is no longer supported; use.getDOMNode().valueinstead this.contexton components is now reserved for internal use by React
- React now never rethrows errors, so stack traces are more accurate and Chrome's purple break-on-error stop sign now works properly

- Boolean attributes such as
disabledare rendered without a value (previouslydisabled="true", now simplydisabled) keyvalues containing.are now supported- Shortened
data-reactidvalues for performance - Components now always remount when the
keyproperty changes - Event handlers are attached to
documentonly when necessary, improving performance in some cases - Events no longer use
.returnValuein modern browsers, eliminating a warning in Chrome scrollLeftandscrollTopare no longer accessed on document.body, eliminating a warning in Chrome- General performance fixes, memory optimizations, improvements to warnings and error messages
React.addons.TestUtilswas added to help write unit testsReact.addons.TransitionGroupwas renamed toReact.addons.CSSTransitionGroupReact.addons.TransitionGroupwas added as a more general animation wrapperReact.addons.cloneWithPropswas added for cloning components and modifying their props- Bug fix for adding back nodes during an exit transition for CSSTransitionGroup

- Fixed a potential XSS vulnerability when using user content as a
key: CVE-2013-7035
- Fixed bug with
<input type="range">and selection events. - Fixed bug with selection and focus.
- Made it possible to unmount components from the document root.
- Fixed bug for
disabledattribute handling on non-<input>elements.
- Fixed bug with transition and animation event detection.
- 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
getInitialStateandgetDefaultPropsin 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.unmountAndReleaseReactRootNodetoReact.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.
- 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.
- No longer transform
classtoclassNameas part of the transform! This is a breaking change - if you were usingclass, you must change this toclassNameor 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.
setStatecallbacks are now executed in the scope of your component.clickevents now work on Mobile Safari.- Prevent a potential error in event handling if
Object.prototypeis 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.
- Improved environment detection so it can be run in a non-browser environment.
- Switch from using
idattribute todata-reactidto 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. propimprovements: validation and default values. Read our blog post for details...- Support for the
keyprop, 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 fordefaultValue, and improved implementation of theonChangeevent, 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.setStatenow takes an optional callback as it's second parameter. If you were usingonClick={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.
- 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 intoReact.DOM.div(null, Component1(null), Component2(null)). Previously this would be transformed intoReact.DOM.div(null, [Component1(null), Component2(null)]). If you were using React without JSX previously, your code should still work.
- Fixed a number of bugs when transforming directories
- No longer re-write
require()s to be relative unless specified
- Allow reusing the same DOM node to render different components. e.g.
React.renderComponent(<div/>, domNode); React.renderComponent(<span/>, domNode);will work now.
- 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.
- Upgrade Commoner so
requirestatements 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 ofbin/jsx. - Upgraded our dependencies on Commoner and Recast so they use a different directory for their cache.
- Freeze our esprima dependency.
- Improved compatability with other coding styles (specifically, multiple assignments with a single
var).
- Switch from using the browserified build to shipping individual modules. This allows react-tools to be used with browserify.
- Fix bug in packaging resulting in broken module.
- Initial public release
