April 2025 — SanteonNL/orca delivered two core items that increase stability, performance readiness, and user efficiency: 1) Frontend dependency upgrades (React 19, sdc-populate) with deliberate compatibility handling (excluding @mui/material to align with @aehrc/smart-forms-renderer) and an updated pnpm-lock.yaml; 2) UX refinement for Task flow: auto-redirect to the Task status page after a new Task, removing scrollToTop logic and simplifying the component by eliminating unused state/effects. These changes are implemented with clear commit accountability (INT-699, INT-700).
