What
The workspace diff shows what has changed in your files. When it looks for nested repositories (git projects inside other projects), it now sorts each .git entry as a folder, something else, or absent. If the only match is not a folder, it is skipped.
Why
Nested projects should be identified more consistently when the diff is built.
Something disagreesSomething we can check disagrees with this entry, or the writer said they could not settle it.
