### SIG Apps

[SIG Apps][] focuses on the Kubernetes APIs and the external tools that are required to deploy and operate Kubernetes workloads.

- External facing APIs in plugin registration and device plugin packages are now available under k8s.io/kubelet/pkg/apis/ ([#83551](https://github.com/kubernetes/kubernetes/pull/83551), [@dims](https://github.com/dims))
### Release

respectively. Signatures of Delete and DeleteCollection methods now accept DeleteOptions by value instead of by reference. Generated clientsets with the previous interface have been added in new "deprecated" packages to allow incremental migration to the new APIs. The deprecated packages will be removed in the 1.21 release. A tool is available at http://sigs.k8s.io/clientgofix to rewrite method invocations to the new signatures.

- The following deprecated metrics are removed, please convert to...

  config migrate" command. For both commands unknown APIs or fields will throw errors. ([#118013](https://github.com/kubernetes/kubernetes/pull/118013), [@neolit123](https://github.com/neolit123))

- kube-apiserver: setting a `dryRun` query parameter on a CONNECT request will now cause the request to be rejected, consistent with behavior of other mutating API requests. Examples of CONNECT APIs are the `nodes/proxy`, `services/proxy`, `pods/proxy`, `pods/exec`, and `pods/attach` subresources. Note that this prevents sending a `dryRun` parameter to backends via `{nodes,services,pods}/proxy` subresources. ([#66083](https://github.com/kuber...

### Other (Cleanup or Flake)

- APIs for kubelet annotations and labels from `k8s.io/kubernetes/pkg/kubelet/apis` are now moved under `k8s.io/kubelet/pkg/apis/` ([#98931](https://github.com/kubernetes/kubernetes/pull/98931), [@michaelbeaumont](https://github.com/michaelbeaumont))

- Fixes a bug where images pinned by the container runtime can be garbage collected by kubelet. ([#1200...

### OpenStack

* Add CRI log parsing library at pkg/kubelet/apis/cri/logs ([#55140](https://github.com/kubernetes/kubernetes/pull/55140), [@feiskyer](https://github.com/feiskyer))
