Jul 1, 2025July 2025 monthly summary focusing on delivering end-to-end frontend UX polish across SAP/luigi, modernizing core examples for React/Svelte, updating Angular onboarding and tooling, and strengthening developer experience with enhanced tooling and documentation. Key user-facing improvements include responsive user settings, consistent menu radii, and a stable global search UI across devices. The core examples were modernized with updated rendering and build configs to better support modern frameworks, while Angular-related enhancements include standalone components, bootstrap API usage, and ESLint migration. Dev tooling improvements (concurrent test setup, browserlist cleanup) and updated container documentation reduce onboarding time and improve maintainability. These efforts collectively improve usability, accelerate integration, and reduce technical debt across the Luigi ecosystem.
