During May 2025, Jun Yong focused on maintaining the integrity of the Homebrew Cask for qBittorrent Enhanced Edition in the lizongying/homebrew-cask repository. He addressed a checksum mismatch by updating the SHA256 value for version 5.1.0.10, ensuring that macOS users could verify the authenticity of downloaded artifacts and reducing the risk of tampered installations. Working primarily with Ruby and leveraging his expertise in Homebrew and package management, Jun Yong committed a targeted fix that restored artifact verification and improved repository traceability. His work demonstrated careful attention to security and repository hygiene, though the scope was limited to a single bug fix.
