In GPL v3.0 paragraph 5a it says:
The work must carry prominent notices stating that you modified it, and giving a relevant date.
Is adding your copyright notice enough? (like described in this question)

Or should there be a separate modification notice? And how should this notice look?
In particular, what is the recommended way of creating a "prominent notice" for a bigger project that includes a modified version of another smaller project licensed under GPL v3.0?
