Revised or altered (7)
I believe the answer is:
amended
I believe this is a double definition.
'revised' is the first definition.
(similar in meaning)
'altered' is the second definition.
(amending is a kind of altering)
(Other definitions for amended that I've seen before include "Revised or altered" , "Made changes to correct" , "Rectified" , "Carried out reforms" , "Modified for the better" .)
