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
React.renderComponentToString --> React.renderToString
React.renderComponentToStaticMarkup --> React.renderToStaticMarkup
React.isValidComponent --> React.isValidElement
React.PropTypes.component --> React.PropTypes.element
React.PropTypes.renderable --> React.PropTypes.node
DEPRECATED React.isValidClass
DEPRECATED instance.transferPropsTo
DEPRECATED Returning false from event handlers to preventDefault
DEPRECATED Convenience Constructor usage as function, instead wrap with React.createFactory
DEPRECATED use of key={null} to assign implicit keys

Bug Fixes

Better handling of events and updates in nested results, fixing value restoration in "layered" controlled components
Correctly treat event.getModifierState as case sensitive
Improved normalization of event.charCode
Better error stacks when involving autobound methods
Removed DevTools message when the DevTools are installed
Correctly detect required language features across browsers
Fixed support for some HTML attributes:
- list updates correctly now
- 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)

Added explicit warning when missing polyfills

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 ES6 transforms available with --harmony option
Added --source-map-inline option to the jsx executable

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

update function to deal with immutable data. Read the docs

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.
