React 15 is out

React version 15.0.0 is out. This is the first major version bump since they decided to shift their minor version to major in order to adhere to semver, which, well good. Semver is useful.

The change looks overall good, mostly focused on cleaning up the DOM that React produces by removing react ids and using HTML comments instead of noscript tags when rendering null.

Word of caution, they have noted that there is an issue with controlled inputs in 15.0.0, and that they're working on an update, so maybe let others test out this version before jumping on board.
