+# Release 3.8.0 (2025-07-10)
+
+* Based on [upstream Nix 2.30.0](../release-notes/rl-2.30.md).
+
+## What's Changed
+
+### Faster CI with `nix flake check`
+
+`nix flake check` no longer downloads flake outputs if no building is necessary.
+
+This command is intended to validate that a flake can fully evaluate and all outputs can build.
+If the outputs are available in a binary cache then both properties are confirmed to be true.
+Notably, downloading the output from the binary cache is not strictly necessary for the validation.
+
+Previously, `nix flake check` would download a flake output if the full build is available in a binary cache.
+
+Some users will find this change significantly reduces costly bandwidth and CI workflow time.
+
+PR: [DeterminateSystems/nix-src#134](https://github.com/DeterminateSystems/nix-src/pull/134)
+
+### Improved flake locking of transitive dependencies
+
+Determinate Nix now re-locks all transitive dependencies when changing a flake input's source URL.
+
+This fixes an issue where in some scenarios Nix would not re-lock those inputs and incorrectly use the old inputs' dependencies.
+
+PR: [DeterminateSystems/nix-src#137](https://github.com/DeterminateSystems/nix-src/pull/137)
