+# Release 2.27.0 (2025-02-26)
+
+- Set FD_CLOEXEC on sockets created by curl [#12439](https://github.com/NixOS/nix/pull/12439)
+
+  Curl creates sockets without setting FD_CLOEXEC/SOCK_CLOEXEC, this can cause connections to remain open forever when using commands like `nix shell`
+
+  This change sets the FD_CLOEXEC flag using a CURLOPT_SOCKOPTFUNCTION callback.
+
+- 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://[email protected]/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;
+  }
+  ```

+- `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`.
