retrieving tabular responses from the server (`Table`) or fetching just the `ObjectMeta` for an object (as `PartialObjectMetadata`) are now beta as part of `meta.k8s.io/v1beta1` and configurations must be changed to use the new API.  Clients may request alternate representations of normal Kubernetes objects by passing an `Accept` header like `application/json;as=Table;g=meta.k8s.io;v=v1beta1` or `application/json;as=PartialObjectMetadata;g=meta.k8s.io;v1=v1beta1`.  Older servers will ignore this representation...

*   kube-apiserver: `--ssh-user` and `--ssh-keyfile` are now deprecated and will be removed in a future release. Users of SSH tunnel functionality in Google Container Engine for the Master -> Cluster communication should plan alternate methods for bridging master and node networks.

### Other (Cleanup or Flake)

- Ingress: Add Exact and Prefix maching to Ingress PathTypes ([#88587](https://github.com/kubernetes/kubernetes/pull/88587), [@cmluciano](https://github.com/cmluciano)) [SIG Apps, Cluster Lifecycle and Network]
- Ingress: Add alternate backends via TypedLocalObjectReference ([#88775](https://github.com/kubernetes/kubernetes/pull/88775), [@cmluciano](https://github.com/cmluciano)) [SIG Apps and Network]

* Supporting only etcd3, with 3.0.14 as the minimum version.
* `kubeadm reset` will no longer drain nodes automatically.  This is because the credentials on nodes do not have permission to perform this operation.  We have documented an [alternate procedure](https://kubernetes.io/docs/getting-started-guides/kubeadm/#tear-down), driven from the API server/master.

- `GlusterFS` in-tree storage driver which was deprecated in kubernetes 1.25 release is now removed entirely in `v1.26`. Volumes must be migrated to an alternate storage solution before upgrading to `v1.26`. ([#112015](https://github.com/kubernetes/kubernetes/pull/112015), [@humblec](https://github.com/humblec))

### Deprecation

- CephFS volume plugin ( `kubernetes.io/cephfs`) was removed in this release and the `cephfs` volume type became non-functional. Alternative is to use CephFS CSI driver (https://github.com/ceph/ceph-csi/) in your Kubernetes Cluster. A re-deployment of your application is required to use the new driver if you were using `kubernetes.io/cephfs` volume plugin before upgrading cluster version...

 - CephFS volume plugin (`kubernetes.io/cephfs`) has been deprecated in this release and will be removed in a subsequent release. The alternative is to use the CephFS CSI driver (https://github.com/ceph/ceph-csi/) in your Kubernetes cluster.

 - `kubeadm`: a separate "super-admin.conf" file is now deployed. The User in `admin.conf` is...
