Worked on the XcodesOrg/homebrew-cask repository to deliver the SwitchHosts 5.0 release, focusing on aligning architecture naming conventions from arm64 to aarch64 and updating the download URL to match the new version. Used Ruby for cask management and version control, refining the livecheck regex to ensure accurate version detection and smoother upgrade experiences for users. The work emphasized release engineering and quality assurance, with careful attention to commit-based traceability. By standardizing architecture references and improving version checks, the changes reduced future maintenance overhead and contributed to a more reliable release process, though no major bugs were addressed this month.
