Plan no longer includes current use (7)
I believe the answer is:
exploit
'use' is the definition.
(exploiting is a kind of using)
I don't understand the rest of the clue.
Can you help me to learn more?
(Other definitions for exploit that I've seen before include "Heroic feat" , "Make use of - great deed" , "put to good use" , "(Mis)use" , "Use to advantage" .)
