February 2025: Delivered a unified App Versioning API for Shopify/cli by consolidating CreateApp and CreateAppVersion mutations into a single AppVersionInput, replacing separate appSource/name fields and introducing initialVersion/version input types to streamline app creation and versioning. This change enhances API consistency, reduces future maintenance, and enables scalable onboarding for developers. The work was implemented through focused mutation-variable updates across CreateApp and CreateAppVersion, supported by two commits that update mutation variables for AppCreate and AppVersionCreate.
