are curr: and test: no longer accepted in .hint files?

[Andrew Schulman]

I tried adding

curr: 1.7.3.2-1
test: 2.0.0-b9-1

to the .hint files in my latest upload of socat. Those fields used to be
supported to indicate current and test versions, but this time I got this
back from calm:

ERROR: package 'socat': unknown key curr at line 10

What's the supported way now to tell calm which versions are previous,
current, and test when you need to override the defaults?

Thanks,
Andrew
