## Changelog since v1.21.8

## Changes by Kind

### Feature

- Removed support for the `v1alpha1` kubeletplugin API of `DynamicResourceManagement`. All plugins must be updated to `v1alpha2` in order to function properly. ([#116558](https://github.com/kubernetes/kubernetes/pull/116558), [@klueska](https://github.com/klueska))

### SIG-service-catalog
- The Originating Identity feature, which lets the broker know which user that performed an action, is now GA.
- [Namespaced Brokers](https://svc-cat.io/docs/namespaced-broker-resources/), which enable operators to install a broker into a namespace instead of the cluster level, reached GA.
