In February 2025, Jonas Bergmann upgraded the hafas-client dependency to version 6.3 within the grafana/k6-DefinitelyTyped repository, focusing on enhancing type safety and data reliability for downstream integrations. He introduced new and improved type definitions in TypeScript, refined ticket and stopover data models, and added support for generating unreliable ticket URLs. His work centered on API integration and careful adjustments to array type definitions, aiming to reduce runtime errors and improve maintainability. No major bugs were reported during this period, reflecting a stable release. The changes provided a stronger foundation for developers working with Hafas-based systems.
