This update introduces GoogleCloudDiscoveryengineV1DataProtectionPolicy across DataStores, DataConnectors, and AssistantCustomerPolicies, allowing developers to link Sensitive Data Protection (DLP) content policies for sanitizing uploads. A new SessionConfig has been added to the Engine resource, enabling control over session TTL (defaulting to 60 days) and management policies (e.g., VERTEX_AI_MANAGED). Additionally, the widgetConfigs.get method now supports an END_USER_MOBILE view for Gemini Enterprise mobile app integrations.
Breaking Change: The iconUrl field within WidgetConfig.UiSettings.ModelConfigInfo.ResolvedModel is now marked as readOnly. Developers who previously attempted to write to this field during configuration updates must now treat it as an output-only absolute URL for brand marks.
