Apple has released an update for the server add-on for OS X 10.8 Mountain Lion, bringing OS X Server to v2.2.1. This update adds the ability to monitor Time Machines backups (which Macs have been backed up, when they were last backed up, size of backup), and provides an interface for centralized certificate management. This update also provides many fixes including: SSL setup failures, deleting apps uploaded to Profile Manager, ability to use AD groups within Profile Manager, and improved caching server speed for software distributed by Apple through the Mac App Store.
