support and new features.
    *   **API not found.** The new optimizer has a different set of public APIs
        from the old optimizer. These API changes are mostly related to
        getting rid of slot variables and TF1 support. Please check the API
        documentation to find alternatives to the missing API. If you must
        call the deprecated API, please change your optimizer to the legacy
        optimizer.

### Deprecation warnings

SIG API Machinery implemented [warnings when using deprecated APIs](https://kubernetes.io/docs/reference/using-api/deprecation-policy/#rest-resources-aka-api-objects)
that are visible to `kubectl` users and API consumers, and metrics visible to cluster administrators.
Requests to a deprecated API are returned with a warning containing a target removal release and any replacement API.
