@mmoayyed Why has @apereocas-bot added this to the 6.1.0-RC1 milestone but #3686 was added to the 6.0.0 milestone?

[mmoayyed]

The bot is out of order and isn't quite cognizant of the CAS release policy just yet. Given the final cut of RC4 and we more or less going into freeze mode, the targetted version should be 6.1.0-RC1. I'll take a pass later today to make the bot behave.
