In April 2025, Sun Yizhou focused on maintenance and documentation improvements across lizongying/homebrew-cask and RSSNext/Folo. He deprecated the discontinued folo@nightly cask in the Homebrew repository, removing outdated installation options and reducing future maintenance overhead. In RSSNext/Folo, he corrected the Homebrew Cask installation URL in the README, ensuring macOS users received accurate onboarding instructions. His work emphasized clear documentation and consistent deprecation status across both repositories, using Markdown for documentation and Ruby for cask management. The scope was targeted, addressing one feature and one bug, and demonstrated careful attention to user experience and repository hygiene within a short timeframe.
