During January 2026, Witty Wizard expanded the InertialIO Libraries Catalog within the arduino/library-registry repository by adding a new repository link to repositories.txt. This update broadened the catalog, improving discoverability and onboarding for Arduino developers seeking InertialIO libraries. Witty Wizard utilized Git-based workflows and repository management skills to ensure accurate catalog maintenance and seamless integration of new entries. The work focused on manifest and metadata updates, contributing to a more complete and maintainable registry. Although no bugs were fixed during this period, the contribution demonstrated a methodical approach to catalog expansion using text-based configuration and collaborative version control practices.
