(2) At trial, if any defendant shows the court that the plaintiff, or any person lawfully on her or his behalf, has delivered a release or covenant not to sue to any person, firm, or corporation in partial satisfaction of the damages sued for, the court shall set off this amount from the amount of any judgment to which the plaintiff would be otherwise entitled at the time of rendering judgment and enter judgment accordingly.
(3) The fact of such a release or covenant not to sue, or that any defendant has been dismissed by order of the court shall not be made known to the jury.
