TL;DR
A final unconditional waiver is the lien-release document a contractor, subcontractor, or supplier signs upon receiving last payment, permanently giving up all mechanics-lien rights on the property with no strings attached. Unlike a conditional waiver, it is effective the moment it is signed even if the check later bounces, which is why signers should exchange it only for cleared funds.
