Ruby on Rails

Hi everyone,

I am happy to announce that Rails 5.2.4.rc1 has been released.

This is going to be the last bug fix release of the 5.2 series, so please test the releases candidates

and report regressions so we can fix before the final release.

If no regressions are found, expect the final release on Wednesday, November 27, 2019.

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.
