I'm a little stuck... Click here to teach me more about this clue!

'thus far?' is the definition.
(I've seen this before)

I don't understand how the rest of the clue works.

(Other definitions for to date that I've seen before include "up to the present day" , "Up to this time - check calendar" , "Thus far" , "Amorous American's aim," , "Up until today" .)

I've seen this clue in The Guardian.
