June 2025 delivered high-impact features, stability improvements, and codebase hygiene across two core repos, strengthening PR velocity, data integrity for admin workflows, and cross-device UX. In KOIN_ADMIN_V2, we implemented an automated PR reviewer assignment workflow and removed CODEOWNERS, accelerating review cycles; delivered a Club Creation & Management UX overhaul with optional descriptions, reliable cancellation/navigation, fixed active state, and admin data model/UI updates (including handling of special characters). A critical fix addressed admin table paging and row-ID ordering to ensure accurate listing of recent requests. In KOIN_WEB_RECODE, dependency and build-tooling cleanup stabilized development workflows (PnP removal, cache tweaks, OS-specific fixes), while footer/privacy UX refinements, Graduation Calculator layout stabilization (min-width), and improved course-table visuals enhanced cross-device usability. A series of codebase refactors unified conventions and reduced maintenance burden, setting a solid foundation for future iterations.
