GxP Impact Assessment

All new TDP functionalities go through a GxP impact assessment to determine validation needs for GxP installations.

New Functionality items marked with an asterisk (*) address usability, supportability, or infrastructure issues, and do not affect Intended Use for validation purposes, per this assessment.

Enhancements and Bug Fixes do not generally affect Intended Use for validation purposes.

Items marked as either beta release or limited availability release (previously early adopter program (EAP)) are not validated for GxP by TetraScience. However, customers can use these prerelease features and components in production if they perform their own validation.

New Functionality

New functionalities are features that weren't previously available in the TDP.

TDP System Administration New Functionality

Fullscreen Mode for Data Apps*

You can now toggle data apps into a fullscreen mode that hides the left navigation panel and the top toolbar, so that you can focus entirely on the app experience. A fullscreen toggle button is visible and accessible whenever a data app is displayed in the Platform UI (PUI).

• Activating fullscreen mode hides both the left navigation panel and the top toolbar from view.
• Deactivating fullscreen mode restores the left navigation panel and top toolbar to their original state.
• Fullscreen mode is available in both the Build and Manage (IT Mode) view and the Sci UX view.
• The fullscreen experience does not interfere with the data app's core functionality or layout.

The fullscreen button is keyboard navigable and includes ARIA labels to meet accessibility standards.
