When upgrade from 0.7.14 to any version up to 0.7.17, I get a lot of such warnings in console:

"Warning: forceUpdate(...): Can only update a mounted or mounting component. This usually means you called forceUpdate() on an unmounted component. This is a no-op."

Application components are not updated, or updated with delay in unpredictable manner. I suppose this breaking changes is caused by the new update queue algorithm introduced in 0.7.15.
Using latest react 0.13.3.
