## [Unreleased]
|
||||
|
||||
### Removed
|
||||
|
||||
- The deprecated CLI utils `step-awskms-init`, `step-cloudkms-init`,
|
||||
`step-pkcs11-init`, `step-yubikey-init` have been removed.
|
||||
[`step`](https://github.com/smallstep/cli) and
|
||||
[`step-kms-plugin`](https://github.com/smallstep/step-kms-plugin) should be
|
||||
used instead.

## [v0.23.1] - 2022-01-10
