# Release 2.27.0 (2025-03-03)
|
|
|
|
- `inputs.self.submodules` flake attribute [#12421](https://github.com/NixOS/nix/pull/12421)
|
|
|
|
Flakes in Git repositories can now declare that they need Git submodules to be enabled:
|
|
```
|
|
{
|
|
inputs.self.submodules = true;
|
|
}
|
|
```
|
|
Thus, it's no longer needed for the caller of the flake to pass `submodules = true`.
|
|
|
|
- Git LFS support [#10153](https://github.com/NixOS/nix/pull/10153) [#12468](https://github.com/NixOS/nix/pull/12468)
|
|
|
|
The Git fetcher now supports Large File Storage (LFS). This can be enabled by passing the attribute `lfs = true` to the fetcher, e.g.
|
|
```console
|
|
nix flake prefetch 'git+ssh://git@github.com/Apress/repo-with-large-file-storage.git?lfs=1'
|
|
```
|
|
|
|
A flake can also declare that it requires LFS to be enabled:
|
|
```
|
|
{
|
|
inputs.self.lfs = true;
|
|
}
|
|
```

- Handle the case where a chroot store is used and some inputs are in the "host" `/nix/store` [#12512](https://github.com/NixOS/nix/pull/12512)
|
|
|
|
The evaluator now presents a "union" filesystem view of the `/nix/store` in the host and the chroot.
|
|
|
|
This change also removes some hacks that broke `builtins.{path,filterSource}` in chroot stores [#11503](https://github.com/NixOS/nix/issues/11503).
|
|
|
|
- `nix flake prefetch` now has a `--out-link` option [#12443](https://github.com/NixOS/nix/pull/12443)
|
|
|
|
- Set `FD_CLOEXEC` on sockets created by curl [#12439](https://github.com/NixOS/nix/pull/12439)
|
|
|
|
Curl created sockets without setting `FD_CLOEXEC`/`SOCK_CLOEXEC`. This could previously cause connections to remain open forever when using commands like `nix shell`. This change sets the `FD_CLOEXEC` flag using a `CURLOPT_SOCKOPTFUNCTION` callback.
|
|
|
|
- Add BLAKE3 hash algorithm [#12379](https://github.com/NixOS/nix/pull/12379)
|
|
|
|
Nix now supports the BLAKE3 hash algorithm as an experimental feature (`blake3-hashes`):
|
|
|
|
```console
|
|
# nix hash file ./file --type blake3 --extra-experimental-features blake3-hashes
|
|
blake3-34P4p+iZXcbbyB1i4uoF7eWCGcZHjmaRn6Y7QdynLwU=
|
|
```
