Calms so those may change (7)

I believe the answer is:

soothes

'calms' is the definition.
(I've seen this in another clue)

'so those may change' is the wordplay.
'may change' indicates an anagram (I've seen this in other clues).
'those' anagrammed gives 'othes'.
'so'+'othes'='SOOTHES'

(Another definition for soothes that I've seen is " 'Allays, comforts, calms (7)'".)

I've seen this clue in the Sydney Morning Herald.
