+
+## What's Changed
+
+### Abbreviate flakerefs in lockfile diffs and `nix flake metadata`
+
+Flake refs are now abbreviated when possible, to reduce visual clutter.

+PR: [DeterminateSystems/nix-src#264](https://github.com/DeterminateSystems/nix-src/pull/264)
+
+### `nix flake prefetch-inputs` now skips build-time inputs
+
+Build-time inputs can already be fetched in parallel, so prefetching them is usually not what you want.
+
+This can be especially noticeable in projects that make extensive use of build-time flake inputs.
+
+PR: [DeterminateSystems/nix-src#263](https://github.com/DeterminateSystems/nix-src/pull/263)
+
+### Don't compute `revCount`/`lastModified` if they're already specified
+
+We don't care if the user (or more likely the lock file) specifies an incorrect value for these attributes, since it doesn't matter for security (unlike content hashes like `narHash`).
+
+This can save time when operating on large repos -- having to recalculate these attributes could slow things down greatly.
+
+PR: [DeterminateSystems/nix-src#269](https://github.com/DeterminateSystems/nix-src/pull/269)
+
+### Avoid unnecessary Git refetches
+
+This fixes the issue where updating a Git input does a non-shallow fetch, and then a subsequent eval does a shallow refetch because the `revCount` is already known.
+
+Now the subsequent eval will reuse the repo used in the first fetch.
+
+PR: [DeterminateSystems/nix-src#270](https://github.com/DeterminateSystems/nix-src/pull/270)
+
+### Use our mirrored flake registry
+
+The flake registry is security-critical and thus should have high availability.
+
+By mirroring the upstream Nix flake registry, we can make it less likely that a GitHub outage affects being able to resolve from the registry.
