Worked on targeted maintenance for the lizongying/homebrew-cask repository, focusing on updating the Beeper Homebrew Cask to version 4.0.604. The work involved modifying the download URL, refining the livecheck strategy, and updating both the application name and trash paths to ensure compatibility with the latest Beeper release. All changes were consolidated into a single commit, emphasizing a streamlined and maintainable approach. Leveraging skills in Ruby and package management, the update improved installation reliability and prepared the cask for future updates. No separate bug fixes were required, as the primary focus was on feature delivery and compatibility enhancements.
