During May 2025, Junyong focused on maintaining the integrity of the Homebrew Cask for qBittorrent Enhanced Edition in the lizongying/homebrew-cask repository. He addressed a critical issue by updating the SHA256 checksum for version 5.1.0.10, ensuring that macOS users could verify artifact authenticity and avoid tampered downloads. Working primarily with Ruby and leveraging expertise in Homebrew and package management, Junyong implemented a targeted bug fix that restored artifact verification and improved repository traceability. Although the work centered on a single bug rather than new features, it demonstrated careful attention to security and the reliability of package distribution workflows.
