Ruby on Rails

I am happy to announce that Rails 4.2.9.rc1 has been released.

If no regressions are found, expect the final release on Monday, June 19, 2017.

If you find one, please open an [issue on GitHub](https://github.com/rails/rails/issues/new)

and mention me (@rafaelfranca) on it, so that we can fix it before the final release.
