Released without charge (4)
I believe the answer is:
free
I believe this is a double definition.
'released' is the first definition.
('free' can be similar in meaning to 'released')
'without charge' is the second definition.
(thesaurus)
(Other definitions for free that I've seen before include "Release; gratis" , "Liberal" , "Unfettered" , "Not restricted or controlled" , "Reef (anag.)" .)
