Interim Releases can be scheduled to run automatically or can be downloaded manually at https://download.novell.com. The Interim releases can be set up within the ZAM Manager for the Task server to check the site on a scheduled basis, and download and apply them automatically. Please refer to the Help Section details of how to set up automatic downloads if desired.
