Git 2.38 Adds Microsoft's "Scalar" Repository Management Tool
Git has been working to improve its handling for very lage repositories and now with the Scalar tool it provides a curated and configured set of features designed to be pre-configured for optimal large repo handling. Scalar by default enables the built-in file-system monitor, multi-pack index, commit graphs, scheduled background maintenance, partial cloning, and clone mode sparse-checkout.
Microsoft had been maintaining Scalar out-of-tree for better large repository integration with Git while now with Git 2.38 it's part of mainline.
Microsoft originally announced Scalar back in 2020 as a .NET Core application for Git. It's since been rewritten in C code.
Git 2.38 also has an assortment of other smaller features, fixes, and optimizations. More details on Git 2.38 via the GitHub blog and release notes on git-scm.com.
