New deed includes it when revised (6)
I believe the answer is:
edited
'revised' is the definition.
(I've seen this in another clue)
'new deed includes it' is the wordplay.
'new' indicates an anagram.
'includes' means one lot of letters goes inside another.
'deed' is an anagram of 'eded'.
'eded' going around 'it' is 'EDITED'.
'when' acts as a link.
(Other definitions for edited that I've seen before include "Amended" , "Prepared text for publication" , "Entrust, commit, deliver" , "Corrected" , "Redacted" .)
