Nov 1, 2025

Month: 2025-11. Key accomplishments for survey-library focused on enhancing file download UX and maintaining cross-framework consistency. Implemented a cross-framework file download behavior to preserve user sessions by opening downloads in a new tab when direct download isn't possible across Angular, React, and Vue3 UI components. Updated snapshot tests to reflect the new behavior and ensure regression safety. All changes centered on improving reliability and user experience with file delivery workflows.
