Nothing whose version ends in "-rc4" is used in "production". You're using it in a very hot beta test.

We ran RC4 in production and we're running 1.12.1GA in production right now as well. We have been making money while running this and serving live customer traffic so we consider it production :)

I hope you have a plan for your paying users when it breaks in production.
