+## 0.4.0 (July 17, 2013)
+
+### React
+
+* Switch from using `id` attribute to `data-reactid` to track DOM nodes. This allows you to integrate with other JS and CSS libraries more easily.
+* Support for more DOM elements and attributes (e.g., `<canvas>`)
+* Improved server-side rendering APIs. `React.renderComponentToString(<component>, callback)` allows you to use React on the server and generate markup which can be sent down to the browser.
+* `prop` improvements: validation and default values. [Read our blog post for details...](http://facebook.github.io/react/blog/2013/07/11/react-v0-4-prop-validation-and-default-values.html)
+* Support for the `key` prop, which allows for finer control over reconciliation. [Read the docs for details...](http://facebook.github.io/react/docs/multiple-components.html)
+* Removed `React.autoBind`. [Read our blog post for details...](http://facebook.github.io/react/blog/2013/07/02/react-v0-4-autobind-by-default.html)
+* 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.
+* Updates to your component are batched now, which may result in a significantly faster re-render of components. `this.setState` now takes an optional callback as it's second parameter. If you were using `onClick={this.setState.bind(this, state)}` previously, you'll want to make sure you add a third parameter so that the event is not treated as the callback.
+
+### JSX
+
+* Support for comment nodes `<div>{/* this is a comment and won't be rendered */}</div>`
+* Children are now transformed directly into arguments instead of being wrapped in an array
+  E.g. `<div><Component1/><Component2></div>` is transformed into `React.DOM.div(null, Component1(null), Component2(null))`.
+  Previously this would be transformed into `React.DOM.div(null, [Component1(null), Component2(null)])`.
+  If you were using React without JSX previously, your code should still work.
+
+### react-tools
+
+* Fixed a number of bugs when transforming directories
+* No longer re-write `require()`s to be relative unless specified
