 # Changelog
 
+## v0.2.0 - 2023-06-02
+
+### Breaking Changes
+
+- `namaka review` now runs `nix eval .#checks` by default instead of `nix flake check`.
+  You can override this behavior by editing `namaka.toml` or using the `--cmd` flag.
+- When provided a directory, namaka now changes the working directory to it,
+  instead of modifying the `nix` commands it runs.
+  This can make a difference if you specify both the directory and `--cmd`.
+
+### Features
+
+- Local configuration with `namaka.toml`
+- `namaka clean` to remove unused and pending snapshots
+- Add `subflake` template for using namaka in a subflake
+
+### Improvements
+
+- `namaka review` now runs faster by default,
+  since the default command has been changed to `nix eval .#checks`.
+
 ## v0.1.1 - 2023-05-02
