 - `React.initializeTouchEvents` is no longer necessary and has been removed completely. Touch events now work automatically.
 - Add-Ons: Due to the DOM node refs change mentioned above, `TestUtils.findAllInRenderedTree` and related helpers are no longer able to take a DOM component, only a custom component.
-- The `props` object is now frozen, so mutating props after creating a component element is no longer supported. In most cases, [`React.cloneElement`](/react/docs/top-level-api.html#react.cloneelement) should be used instead. This change makes your components easier to reason about and enables the compiler optimizations mentioned above.
-- Plain objects are no longer supported as React children; arrays should be used instead. You can use the [`createFragment`](/react/docs/create-fragment.html) helper to migrate, which now returns an array.

 - Add-Ons: `classSet` has been removed. Use [classnames](https://github.com/JedWatson/classnames) instead.
 - Web components (custom elements) now use native property names.  Eg: `class` instead of `className`.

 - `this.getDOMNode()` is now deprecated and `ReactDOM.findDOMNode(this)` can be used instead. Note that in the common case, `findDOMNode` is now unnecessary since a ref to the DOM component is now the actual DOM node.
 - `setProps` and `replaceProps` are now deprecated. Instead, call ReactDOM.render again at the top level with the new props.
-- ES6 component classes must now extend `React.Component` in order to enable stateless function components. The [ES3 module pattern](/react/blog/2015/01/27/react-v0.13.0-beta-1.html#other-languages) will continue to work.

 - Reusing and mutating a `style` object between renders has been deprecated. This mirrors our change to freeze the `props` object.
-- Add-Ons: `cloneWithProps` is now deprecated. Use [`React.cloneElement`](/react/docs/top-level-api.html#react.cloneelement) instead (unlike `cloneWithProps`, `cloneElement` does not merge `className` or `style` automatically; you can merge them manually if needed).

 - Add-Ons: To improve reliability, `CSSTransitionGroup` will no longer listen to transition events. Instead, you should specify transition durations manually using props such as `transitionEnterTimeout={500}`.

-- The `react-tools` package and `JSXTransformer.js` browser file [have been deprecated](/react/blog/2015/06/12/deprecating-jstransform-and-react-tools.html). You can continue using version `0.13.3` of both, but we no longer support them and recommend migrating to [Babel](http://babeljs.io/), which has built-in support for React and JSX.

 * Support for using ES6 classes to build React components; see the [v0.13.0 beta 1 notes](https://facebook.github.io/react/blog/2015/01/27/react-v0.13.0-beta-1.html) for details.
 * Added new top-level API `React.findDOMNode(component)`, which should be used in place of `component.getDOMNode()`. The base class for ES6-based components will not have `getDOMNode`. This change will enable some more patterns moving forward.
-* Added a new top-level API `React.cloneElement(el, props)` for making copies of React elements – see the [v0.13 RC2 notes](/react/blog/2015/03/03/react-v0.13-rc2.html#react.cloneelement) for more details.

 * New `ref` style, allowing a callback to be used in place of a name: `<Photo ref={(c) => this._photo = c} />` allows you to reference the component with `this._photo` (as opposed to `ref="photo"` which gives `this.refs.photo`).
 * `this.setState()` can now take a function as the first argument for transactional state updates, such as `this.setState((state, props) => ({count: state.count + 1}));` – this means that you no longer need to use `this._pendingState`, which is now gone.
 * Support for iterators and immutable-js sequences as children.
