Git 2.42 release: Here are four of our contributions in detail

GitLab's Git team contributed to Git 2.42 by adding `--include` and `--exclude` options to `git pack-refs` to manage temporary references for Gitaly's write-ahead logging, implementing the `-Z` option for `git cat-file --batch` to use NUL delimiters for safer input/output parsing, and enabling the passing of pseudo-options via stdin to `git rev-list --stdin` for improved disk usage calculations. They also contributed code style and refactoring improvements to the Git codebase.
