To support the Benign with Low Confidence verdict, a new field was added to the WildFire verdict local database. As a result, when you upgrade a Cortex XDR agent release prior to 7.5 to a Cortex XDR agent 7.5, the local WildFire cache is deleted, which could increase the number of initial WildFire queries on the endpoint after upgrade.

To comply with the new operating system behavior starting with macOS 11.3, where uploading a configuration file in MDM automatically unloads from the endpoint any previously uploaded extensions by the same vendor, the Cortex XDR agent 7.5 and later retains its extensions on the endpoint in such cases.

To improve user experience, now when you uninstall the Cortex XDR agent from endpoints running macOS 10.15.4 or later, you are prompted only once to enter your admin password.
