Aug 1, 2025August 2025 (opengovsg/plumber) - Delivered secure, scalable enhancements across authentication, navigation, data migration, and administration, while improving test coverage and release hygiene. SSO integration established with backend config, environment variables, and a callback mutation, reducing friction and increasing security. A new 'View tile' action streamlined navigation to tile details. sgID to MyInfo backward compatibility ensures form continuity during migration, with field duplication and mapping logic. Tiles v2 core improvements hardened numeric comparisons, added a validation helper, and expanded integration tests for reliability. Admin mutations to pause/resume groups, plus a query to list paused groups, give operators safer control over workloads. Release tagging updated to v1.50.3 and v1.51.2 for tighter release tracking.
