# Changelog

## [0.2.1](https://github.com/godaddy/cli-engine/compare/cli-engine-v0.2.0...cli-engine-v0.2.1) (2026-06-10)


### Features

* argv0 multi-call dispatch with link/shim installer ([#19](https://github.com/godaddy/cli-engine/issues/19)) ([9e39f2f](https://github.com/godaddy/cli-engine/commit/9e39f2fa7aca9b60fa898e33eb9a2a92d93bf350))
* OAuth scope step-up via command metadata ([#18](https://github.com/godaddy/cli-engine/issues/18)) ([f996e50](https://github.com/godaddy/cli-engine/commit/f996e5074c417c798a289d4d87fc283f78672c45))

## [0.2.0](https://github.com/godaddy/cli-engine/compare/cli-engine-v0.1.3...cli-engine-v0.2.0) (2026-06-09)


### ⚠ BREAKING CHANGES

* `CommandSpec.no_auth` (bool) is replaced by `CommandSpec.auth` (`AuthRequirement`), and `MiddlewareRequest.no_auth` by `MiddlewareRequest.auth`. `CommandContext.credential` is now a `CredentialResolver` instead of `Option<Credential>`; `RuntimeCommandSpec::new` and `new_typed` handler closures receive a `CredentialResolver`; and `Authorizer::authorize` receives `&CredentialResolver` instead of `Option<&Credential>`. The `no_auth(true)` builder still works and maps to `AuthRequirement::None`; `auth_optional()` and `auth(AuthRequirement)` select the other policies.

### Features

* fail-closed authentication via AuthRequirement; populate PKCE identity ([#17](https://github.com/godaddy/cli-engine/issues/17)) ([34313bf](https://github.com/godaddy/cli-engine/commit/34313bf28b63270a151cd19de5d1f3b4665177e5))

## [0.1.3](https://github.com/godaddy/cli-engine/compare/cli-engine-v0.1.2...cli-engine-v0.1.3) (2026-06-05)
