'just released' is the definition.
The answer and definition are different parts of speech. However, past participle verbs and adjectives can occasionally mean the same thing.

'cereal wendy briefly promoted' is the wordplay.
'cereal' becomes 'bran' (type of cereal).
'briefly' means to remove the last letter.
'promoted' says the letters should be written backwards (going up, in a down clue).
'wendy' with its last letter taken away is 'wend'.
'wend' backwards is 'dnew'.
'bran'+'dnew'='BRAND-NEW'

Can you help me to learn more?
