Is there a way to get only the latest validity?

[Madd0g]

if I just ask for the validity field - I get all of the validity records.
if I ask for valid @ 'NOW', I get only records that are valid.

But how do I get only the latest validity, true or false?

I tried something with to_int(valid) and trying to find the max, but got lost.

actually, it seems like it's possible with latest_by, would be cool if it supported validity natively, I had to extract the timestamp/bool out first before passing to latest_by, but it works.
