Herald procures new editor, finally (9)
I believe the answer is:
precursor
'herald' is the definition.
('precursor' can be a synonym of 'herald')
'procures new editor finally' is the wordplay.
'new' is an anagram indicator.
'finally' suggests the final letters.
The final letter of 'editor' is 'r'.
'procures' anagrammed gives 'precurso'.
'precurso'+'r'='PRECURSOR'
(Other definitions for precursor that I've seen before include "harbinger of what is to follow" , "Forerunner, predecessor" , "Something going in advance of another" , "I was here first" , "Herald" .)
