Disclosures that several changes need to be made (7)

I believe the answer is:

reveals

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

'be made' is the definition.
I can't judge whether this defines the answer.

'disclosures that several changes need' is the wordplay.
'several' can be anagrammed to 'REVEALS'.
Though, I am not clear how this is indicated.

'to' acts as a link.

Can you help me to learn more?

(Other definitions for reveals that I've seen before include "Unmasks" , "Shows" , "Discloses" , "Several (anag)" , "Upright sides of doors and windows" .)

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