May 1, 2025May 2025 (mendersoftware/mender-server) monthly summary focused on stabilizing the GUI, improving state management, and polishing UI interactions to reduce flaky behavior and accelerate release cycles. Key outcomes include more reliable GUI tests through act-based state management and JWT test fixes, memoization improvements via Redux slices, UI correctness fixes (button nesting, key props, and placeholder types), testing infrastructure enhancements (terminal/Windows mocks and deployment test tweaks), code quality gains (removing redundant thunk dispatches and resolving circular dependencies), and UX drawer behavior fixes (device-config cancel, Roles & Users drawer closing, deployment drawer animation). These efforts reduce risk, shorten feedback loops, and improve developer velocity and user experience.
