All links are optional fields.
`require` and `require-dev` additionally support stability flags ([root-only](04-schema.md#root-package)).
`require` and `require-dev` additionally support _stability flags_ ([root-only](04-schema.md#root-package)).
They take the form "_constraint_@_stability flag_".
These allow you to further restrict or expand the stability of a package beyond
the scope of the [minimum-stability](#minimum-stability) setting. You can apply
them to a constraint, or apply them to an empty constraint if you want to
them to a constraint, or apply them to an empty _constraint_ if you want to
allow unstable packages of a dependency for example.
