Refreshed by fruit-filled baked pud (7)
I believe the answer is:
updated
'refreshed' is the definition.
'fruit-filled baked pud' is the wordplay.
'fruit' becomes 'date' (date is a kind of fruit).
'filled' means one lot of letters goes inside another.
'baked' indicates an anagram.
'pud' anagrammed gives 'upd'.
'date' going into 'upd' is 'UPDATED'.
'by' is the link.
(Other definitions for updated that I've seen before include "Modernised" , "Made something more modern" , "Brought to current status" , "Dude apt to be made current" , "Brought to current level of completeness" .)
