Free news publication (7)

I believe the answer is:

release

I'm a little stuck... Click here to teach me more about this clue!

This might be a double definition.

'free' is the first definition.
(to release someone is to free them)

'news publication' is the second definition.
'release' can be an answer for 'publication' (thesaurus). I am unsure of the 'news' bit.

Can you help me to learn more?

(Other definitions for release that I've seen before include "record" , "Possibly film" , "Liberate" , "press announcement" , "Free - delivery" .)

I've seen this clue in The Globe and Mail.
