  `result == nil` rather than `err != nil`, and in some cases may expose bugs
  in the underlying code that were hidden by the incorrect unit tests. ([#122892](https://github.com/kubernetes/kubernetes/pull/122892), [@danwinship](https://github.com/danwinship)) [SIG API Machinery, Auth, Cloud Provider, Instrumentation and Storage]

- Fixed the deprecated version for `pod_scheduling_duration_seconds` that caused the metric to be hidden by default in `1.29`.

  * The gce metadata server can now be hidden behind a proxy, hiding the kubelet's token. ([#45565](https://github.com/kubernetes/kubernetes/pull/45565), [@Q-Lee](https://github.com/Q-Lee))

* OpenStack:

  * kubectl describe no longer prints the last-applied-configuration annotation for secrets. ([#34664](https://github.com/kubernetes/kubernetes/pull/34664), [@ymqytw](https://github.com/ymqytw))
  * Completed pods should not be hidden when requested by name via `kubectl get`. ([#42216](https://github.com/kubernetes/kubernetes/pull/42216), [@smarterclayton](https://github.com/smarterclayton))

- Kubernetes now includes an alpha field, `AllowWatchBookmarks`, in ListOptions for requesting the watching of bookmarks from apiserver. The implementation in apiserver is hidden behind the feature gate `WatchBookmark`. ([#74074](https://github.com/kubernetes/kubernetes/pull/74074), [@wojtek-t](https://github.com/wojtek-t))

### Staging Repositories

- `kubectl exec` and `kubectl attach` now honor the `--quiet` flag which suppresses output from the local binary that could be confused by a script with the remote command output (all non-failure output is hidden). In addition, print inline with exec and attach the list of alternate containers when we default to the first spec.container.
