Worked on the lizongying/homebrew-cask repository to update the GitKraken CLI Cask to version 3.0.0, focusing on improving package management for macOS users. Addressed packaging inconsistencies by migrating architecture identifiers from macOS_arm64 and macOS_x86_64 to darwin_arm64 and darwin_amd64, ensuring compatibility across Apple Silicon and Intel Macs. Updated download URLs and SHA256 checksums, validating the installer flow to prevent faulty installations. Leveraged Ruby and Homebrew Cask expertise to align with current standards, providing a more reliable upgrade path for developers. All changes were consolidated in a single, auditable commit to maintain traceability and repository integrity.
