 ### Features Added
 
 - `InteractiveBrowserBrokerCredential` now supports a `use_operating_system_account` property to enable the use of the currently logged in operating system account for authentication rather than prompting for a credential.
+- Added `enable_support_logging` as a keyword argument to `InteractiveBrowserBrokerCredential`. This allows additional support logging which may contain PII.
