            • Perspectives with > 10,000 result rows will be lazy-loaded.  This will be more efficient.  The user can select the results in the context panel
            • Top Contributors can now be modified for perspectives with a limited result set.  Users can modify the number of result rows returned, or request "All".  For large systems with many jobs, threads, or tasks, selecting "All" might extend the time to display results significantly.

              • For Message Monitors:
                • View monitors and event logs
                • Change monitors
              • For System Monitors:
                • View monitors and event logs
                • Change monitors
                • View monitor charts
              • Monitor GUI supports the authority management, administrators can grant or remove read access for specific *USER profiles.

            • For time intervals that will return more than 500,000 rows of data, the server will time out, and the GUI will show the spinning "loading" icon indefinitely.  This can be resolved by clicking "actions", then "View Configuration", and selecting a shorter time interval.
        • Network - IP Policies > Packet rules list and actions are added
        • Network - TCP/IP Servers > Directory Server (LDAP) - Manage Instances, the LDAP instances list and actions are added
        • Network - TCP/IP Configuration > Lines - minor updates to strings used
        • Active Jobs updates
          • Basic, Work, and All selections for varying level of results.  This allows a large system with large number of jobs to use "Basic" and see better performance.
