# Release 2.14 (2023-02-28)
* A new function `builtins.readFileType` is available. It is similar to
`builtins.readDir` but acts on a single file or directory.
* In flakes, the `.outPath` attribute of a flake now always refers to
the directory containing the `flake.nix`. This was not the case for
when `flake.nix` was in a subdirectory of e.g. a Git repository.
The root of the source of a flake in a subdirectory is still
available in `.sourceInfo.outPath`.
* In derivations that use structured attributes, you can now use `unsafeDiscardReferences`
to disable scanning a given output for runtime dependencies:
```nix
__structuredAttrs = true;
unsafeDiscardReferences.out = true;
```
This is useful e.g. when generating self-contained filesystem images with
their own embedded Nix store: hashes found inside such an image refer
to the embedded store and not to the host's Nix store.
This requires the `discard-references` experimental feature.
