seeds::program is out of data?

[cxp-13]

    #[account(
        mut,
        seeds = [
            METADATA_SEED.as_bytes(),
            token_metadata_program.key().as_ref(),
            mint.key().as_ref(),
        ],
        seeds::program = token_metadata_program.key(),
        bump
    )]
    pub metadata: UncheckedAccount<'info>,

this is a part of a project based on the 0.30.1 anchor version. the seeds::program appear at 0.20.1 version on Anchor document. Is there any ways can judge whether the attribute is working on current anchor version ?
