Jun 1, 2025June 2025 monthly summary for SchweizerischeBundesbahnen/DAS focusing on delivering business value through release automation, authentication flexibility, frontend modernization, and telematics data modeling. Key outcomes include automated release artifact handling with generated API documentation as a release asset, refactored CI/CD release actions for clearer environment variable naming and using GitHub release uploads, and improvements in release reliability. Implemented a flexible authentication configuration using a new APIM auth client with service-name references, environment-based client IDs and scopes, and a backend test profile to ensure tests run with proper authentication parameters. Upgraded the frontend to Angular v20 (with Node.js update) and modernized dependency injection, improving maintainability and performance. Introduced TrainFormationRunEntity data model and SQL migration to store train run operational and physical details in line with telematics standards. Fixed critical issues in release actions and backend tests to enhance reliability and reduce defects. Overall impact includes shortened release cycles, more reliable testing, and enhanced data modeling for analytics and compliance.

Jan 1, 2025January 2025 (SchweizerischeBundesbahnen/DAS) — Delivered a focused set of backend improvements to boost maintainability, observability, and developer velocity, while simplifying access control and removing outdated components to reduce maintenance overhead. Highlights include a backend code structure refactor with a new shared 'common' package and streamlined logging/service modules; removal of the deprecated Preload module and related artifacts (docs, Docker Compose, application properties, schema, and integration tests); enablement of health probes and management endpoints for improved operational visibility; and relaxed API access control, removing the admin role requirement so any authenticated user can access /api/**, improving user onboarding and reducing friction for frontline consumers. These changes reduce maintenance burden, improve runtime insight, and preserve security through mandatory authentication for all endpoints.
