state-of-the-art

But I can't explain it at all!

(Other definitions for state-of-the-art that I've seen before include "Using latest technology" , "Incorporating the newest ideas and features" , "Technologically up to date" , "Produced by the latest technology" , "Highest level of development at the present time" .)

I've seen this clue in The Times.
