Introduces ten changes in newspapers (8)
I believe the answer is:
presents
'introduces' is the definition.
('present' can be a synonym of 'introduce')
'ten changes in newspapers' is the wordplay.
'changes' indicates anagramming the letters.
'in' is an insertion indicator.
'newspapers' becomes 'press' (I've seen this before).
'ten' with letters rearranged gives 'ent'.
'ent' inserted inside 'press' is 'PRESENTS'.
(Other definitions for presents that I've seen before include "tips" , "Introduces" , "Press ten (anag.)" , "Awards formally" , "special things at Christmas?" .)
