- Fix azure disk naming matching issue due to case sensitive comparison ([#81720](https://github.com/kubernetes/kubernetes/pull/81720), [@andyzhangx](https://github.com/andyzhangx))

* Limit use of tags when calling EC2 API to prevent API throttling for very large clusters ([#76749](https://github.com/kubernetes/kubernetes/pull/76749), [@mcrute](https://github.com/mcrute))
* fix azure disk naming matching issue due to case sensitive comparison ([#81720](https://github.com/kubernetes/kubernetes/pull/81720), [@andyzhangx](https://github.com/andyzhangx))

- Added optional `--detect-local-mode` flag to kube-proxy. Valid values are "ClusterCIDR" (default matching previous behavior) and "NodeCIDR" ([#87748](https://github.com/kubernetes/kubernetes/pull/87748), [@satyasm](https://github.com/satyasm)) [SIG Cluster Lifecycle, Network and Scheduling]

- Kube-apiserver: The timeout used when making health check calls to etcd can now be configured with `--etcd-healthcheck-timeout`. The default timeout is 2 seconds, matching the previous behavior. ([#93244](https://github.com/kubernetes/kubernetes/pull/93244), [@Sh4d1](https://github.com/Sh4d1)) [SIG API Machinery]

* kubectl cp now safely allows unpacking of symlinks that may point outside the destination directory ([#82384](https://github.com/kubernetes/kubernetes/pull/82384), [@tallclair](https://github.com/tallclair))
* fix azure disk naming matching issue due to case sensitive comparison ([#81720](https://github.com/kubernetes/kubernetes/pull/81720), [@andyzhangx](https://github.com/andyzhangx))

- The errors in `k8s.io/apimachinery/pkg/api/meta` now support for the `stdlibs` `errors.Is` matching, including when wrapped. ([#111808](https://github.com/kubernetes/kubernetes/pull/111808), [@alvaroaleman](https://github.com/alvaroaleman))

        etc.) may break.
    *   Code that uses full path for `get_concrete_function` to trace Keras
        symbolic inputs directly should switch to building matching
        `tf.TensorSpec`s directly and tracing the `TensorSpec` objects.
    *   Code that relies on the exact number and names of the op layers that
        TensorFlow operations were converted into may have changed.

* kubeadm now detects the Docker cgroup driver and starts the kubelet with the matching driver. This eliminates a common error experienced by new users in when the Docker cgroup driver is not the same as the one set for the kubelet due to different Linux distributions setting different cgroup drivers for Docker, making it hard to start...

- NONE ([#124326](https://github.com/kubernetes/kubernetes/pull/124326), [@ritazh](https://github.com/ritazh)) [SIG Auth]
- OpenAPI V2 will no longer publish aggregated apiserver OpenAPI for group-versions not matching the APIService specified group version ([#123625](https://github.com/kubernetes/kubernetes/pull/123625), [@Jefftree](https://github.com/Jefftree)) [SIG API Machinery and Testing]
