Read this, it's important!

Do not let npm confuse you: there used to be another project with the same name that the previous owner nuked. Unfortunately, removing or re-publishing old versions is no longer supported by npm. So packages that are tagged < v2.0.0 on npm are artifacts of a different project, and the first stable version of this library will be released as v2.0.0 and strictly follow the React Versioning Scheme afterwards.
