Recent change to middle (6)
I believe the answer is:
centre
'middle' is the definition.
(synonyms)
'recent change' is the wordplay.
'change' is an anagram indicator.
'recent' anagrammed gives 'CENTRE'.
'to' is the link.
(Other definitions for centre that I've seen before include "and this may follow 26, 25 [LEFT RIGHT]" , "focus" , "Heart" , "'Things fall apart; the ... cannot hold' (Yeats)" , "Midpoint" .)
