Apple has just released the 2.2.1 update for OS X Server.
The update includes features such as a caching server (to speed up the transfer of software distributed by Apple through the Mac App Store), Time Machine service that monitors the computers that were backed up (when they did and the file size generated), compatibility with the Wiki server for Retina screens, the ability to use Active Directory groups and an interface for centralized certificate management.
In addition, it corrects an issue that did not allow deleting applications sent to the Profile Manager, configuration failures due to an SSL error, and problems updating the Lion Server.
