Recent changes in middle (6)
I believe the answer is:
centre
'middle' is the definition.
(I know that middle can be written as centre)
'recent changes' is the wordplay.
'changes' indicates an anagram.
'recent' with letters rearranged gives 'CENTRE'.
'in' is the link.
(Other definitions for centre that I've seen before include "- forward; - punch" , "The point equidistant from everything" , "and this may follow 26, 25 [LEFT RIGHT]" , "Heart" , "Player" .)
