 This release is the result of several months of hard work from members of the team and the community. While there are no groundbreaking changes in core, we've worked hard to improve performance and memory usage. We've also worked hard to make sure we are being consistent in our usage of DOM properties.
 
-The biggest change you'll notice as a developer is that we no longer support `class` in JSX as a way to provide CSS classes. Since this prop was being converted to `className` at the transform step, it caused some confusion when trying to access it in composite components. As a result we decided to make our DOM properties mirror their counterparts in the JS DOM API. There are [a few exceptions](https:/facebook/react/blob/master/src/dom/DefaultDOMPropertyConfig.js#L156) where we deviate slightly in an attempt to be consistent internally.

 The other major change in v0.5 is that we've added an additional build - `react-with-addons` - which adds support for some extras that we've been working on including animations and two-way binding. [Read more about these addons in the docs](/docs/addons.html).

 When a user interacts with a React view, the view sends an action (usually represented as a JavaScript object with some fields) through the dispatcher, which notifies the various stores that hold the application's data and business logic. When the stores change state, they notify the views that something has updated. This works especially well with React's declarative model, which allows the stores to send updates without specifying how to transition views between states.
