{this, true, "nix-shell-always-looks-for-shell-nix", R"(
Before Nix 2.24, [`nix-shell`](@docroot@/command-ref/nix-shell.md) would only look at `shell.nix` if it was in the working directory - when no file was specified.
Since Nix 2.24, `nix-shell` always looks for a `shell.nix`, whether that's in the working directory, or in a directory that was passed as an argument.
You may set this to `false` to temporarily revert to the behavior of Nix 2.23 and older.
Using this setting is not recommended.
It will be deprecated and removed.
