What Git does
Git is a GPL-licensed distributed version-control system developed by its contributor community. Git is a member project of Software Freedom Conservancy; the Windows distribution linked here is maintained by the separate Git for Windows project. A normal clone can contain project history and supports local commits, branches, diffs, and merges before remote synchronization; cloning, fetching, pushing, LFS objects, submodules, credential-provider flows, and hosted pull-request features still require access to their configured remotes. Whether all needed history and objects are local also depends on shallow, partial, sparse, submodule, and LFS choices.
This record pins Git for Windows release v2.55.0.windows.5. It lists x64 and ARM64 installers plus x64 PortableGit. GitHub's official release metadata provides immutable SHA-256 digests for those assets. PortableGit avoids a conventional installation but still writes repository data and user configuration and can invoke credential helpers or external tools. The Windows installer exposes choices for PATH integration, terminal, credential handling, line endings, filesystem behavior, default branch, and editor; this audit did not run the installer and therefore does not claim a tested option set. Administrators should record and validate the choices they actually deploy.
Git packaging on macOS and Linux is not maintained by Git for Windows. The additional rows deliberately link to Git's official platform instructions rather than pretending they are immutable binary artifacts; exact versions, paths, signatures, and update mechanisms depend on Homebrew, Xcode Command Line Tools, a distribution package manager, or a source build. Remote authentication and trust depend on the chosen transport, credential helper, host-key or TLS validation, and hosting service.
