More up-to-date (5)
I believe the answer is:
newer
'more up-to-date' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for newer that I've seen before include "More modern" , "Fresher or more novel" , "More pristine or recently invented" , "More recent" , "Fresher, not as old" .)
