 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://github.com/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).

 We updated the license on React to the BSD 3-Clause license with an explicit patent grant. Previously we used the Apache 2 license. These licenses are very similar and our extra patent grant is equivalent to the grant provided in the Apache license. You can still use React with the confidence that we have granted the use of any patents covering it. This brings us in line with the same licensing we use across the majority of our open source projects at Facebook.
