April 2025 delivered customer-facing information access enhancements, user experience refinements, and targeted technical cleanup across two repositories (NIAEFEUP/enei and NIAEFEUP/uni). The month focused on publishing essential competition documents, empowering users with relevant campus-based filtering, and reducing maintenance risk through codebase cleanup and feature removal where appropriate. The result is clearer onboarding, more relevant discovery, and a leaner, more maintainable codebase that supports faster future delivery.
