What
A setup step called shallow-pins now stops early when its check finds no git data in the folder (no_git_dir). The step also decides this from the result of that check rather than from the input it was given.
Why
In practice, folders that are not git repositories now skip this step instead of going through it.
Something disagreesSomething we can check disagrees with this entry, or the writer said they could not settle it.
The writer flagged doubt
The finding does not say what the shallow-pins step does or when a reader would notice it.
