The reason CROPS is no longer available is due to a Hazard Identification workshop created due to an incident a few months ago. A cirrus had a rejected landing ( after the third bounce!) and nearly took out a QF 737.
P-Dubby is correct with the limitations he mentioned.
The 5 kts down wind however remains; mitigated by the 5 mil;e fianl requirement.
The reason that CROPS has been suspended at night is that there is no way for the controller to issue avoidance heading at night below the MVA.
I have heard that the evening sequence is now lasting a little longer....
