 # NH Changelog
 
+## 4.0.3
+
+### Added
+
+- Nh now supports specifying `NH_SUDO_ASKPASS` to pass a custom value to

+  `-A` and the `NH_SUDO_ASKPASS` will be `SUDO_ASKPASS` locally.
+
+### Fixed
+
+- Fix `--configuration` being ignored in `nh home switch`
+  ([#262](https://github.com/nix-community/nh/issues/262))
