We have already released two release candidates for React 15, and the final version is coming soon.
However [Ian Christian Myers](https://github.com/iancmyers) discovered a memory leak related to server rendering in React 0.14 and [contributed a fix](https://github.com/facebook/react/pull/6060). While this memory leak has already been fixed in a different way in the React 15 release candidates, we decided to cut another 0.14 release that contains just this fix.
