0.11.0 (July 17, 2014)

React Core

Breaking Changes

• getDefaultProps() is now called once per class and shared across all instances

• 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

• Re-renders are batched in more cases

  • Changing className on a mounted SVG component now works correctly
  • Added support for elements mask and tspan
  • Added support for attributes dx, dy, fillOpacity, fontFamily, fontSize, markerEnd, markerMid, markerStart, opacity, patternContentUnits, patternUnits, preserveAspectRatio, strokeDasharray, strokeOpacity
• 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)
• img event listeners are now unbound properly, preventing the error "Two valid but unequal nodes with the same data-reactid"
• 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

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)

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

• 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.

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

• React.renderComponentToString is 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, 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
