During June 2026, work focused on enhancing the heremaps/xyz-hub repository by developing the Map Changeset Media Type for Layer Updates. This feature introduced the application/vnd.here.map-changeset content type, enabling the API to support changesets within map layers. The approach streamlined incremental map updates, improving data consistency and accelerating refresh cycles across the platform. Implementation relied on Java and API development skills, with careful attention to code quality and traceability through signed-off commits. No major bugs were addressed during this period, as efforts centered on expanding API capabilities to better support reliable, incremental updates for map data management workflows.
