Tom McKnight upgraded the .NET SDK and Runtime to version 10.0.x in the Homebrew/homebrew-cask repository, focusing on security, compatibility, and maintainability. He implemented new SHA256 checksums for both ARM and Intel architectures, ensuring release integrity and reproducible builds. Using Ruby and Homebrew’s package management framework, Tom maintained alignment with platform features and streamlined the release engineering process. His work enabled downstream users to access the latest .NET features while reducing future maintenance overhead. Although no major bugs were addressed during this period, the depth of the feature work demonstrated careful attention to cross-architecture support and release hygiene.
