The lifecycle methods componentDidMount and componentDidUpdate no longer receive the root node as a parameter; use this.getDOMNode() instead
Whenever a prop is equal to undefined, the default value returned by getDefaultProps will now be used instead
React.unmountAndReleaseReactRootNode was previously deprecated and has now been removed

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

CSS property values no longer have px appended for the unitless properties columnCount, flex, flexGrow, flexShrink, lineClamp, order, widows
Fixed a memory leak when unmounting children with a componentWillUnmount handler
