## Improvements

- The `systemd_unit` resource now respects the `sensitive` property and will no longer output the contents of the unit file to logs if this is set.
- A new `arm?` helper has been added which can be used in recipes and resources to determine if a system is on the ARM architecture.

## Bug Fixes

- Resolved a bug that prevented users from bootstrapping nodes using knife when specifying the `--use_sudo_password`.
- Resolved a bug that prevented the `--bootstrap-version` flag from being honored when bootstrapping in knife.
