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

Bug Fixes

  • 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

• Perf: a new set of tools to help with performance analysis

• Added --source-map-inline option to the jsx executable
