 * Improvements to forms. We've written wrappers around `<input>`, `<textarea>`, `<option>`, and `<select>` in order to standardize many inconsistencies in browser implementations. This includes support for `defaultValue`, and improved implementation of the `onChange` event, and circuit completion. [Read the docs for details...](http://facebook.github.io/react/docs/forms.html)
 * We've implemented an improved synthetic event system that conforms to the W3C spec.

What is returned from `render()`` is not your actual composition of "child" components, it is merely a *description* of the children at a particular instance in time - a snapshot, if you will.
