Fixed: AsyncOS Upgrades and Service Updates Use Same Update Server
In AsyncOS 7.5, AsyncOS upgrades used the same update server as all of the service
updates, whether it was an IronPort update server or a local update server. This
prevented users from using a local server for AsyncOS upgrades and an IronPort
update server for all other service updates unless they configure the appliance to use
a manifest on a local appliance for an AsyncOS upgrade and then re-configure the
appliance to use an IronPort update server for the other services after the upgrade is
complete.

This issue has been resolved. AsyncOS 7.6 allows you to specify a different update
server for AsyncOS upgrades than the one used for other service updates, such as
feature key updates, outbreak filters, and time zone rules.

per page than expected. For example, if you selected to view 50 items of your query
results per page, the GUI may have displayed only 20 per page, even though the page
may have said "Displaying 1-50 of 120 items." This issue has been resolved
