o motion to amend the complaint was filed, and neither the magistrate judge nor the district court said the complaint had been amended. The plaintiffs did file a motion to withdraw their request for injunctive relief, which simply acknowledged that there was no longer any need for an injunction in view of their release. But the court did not formally rule on that motion. Instead, the magistrate judge (whose recommendations were adopted by the district court without relevant change) concluded: "These plaintiffs cannot obtain monetary relief because they alleged only mental or emotional injuries and their injunctive claims are moot since they have been released from prison."
