* Adding support for Block Volume type to rbd plugin. ([#56651](https://github.com/kubernetes/kubernetes/pull/56651), [@sbezverk](https://github.com/sbezverk))

- Deprecate the instance type beta label (`beta.kubernetes.io/instance-type`) in favor of its GA equivalent: `node.kubernetes.io/instance-type` ([#82049](https://github.com/kubernetes/kubernetes/pull/82049), [@andrewsykim](https://github.com/andrewsykim))

### Deprecated/changed metrics

- kubelet probe metrics are now of the counter type rather than the gauge type, and the `prober_probe_result` has been replaced by `prober_probe_total`. ([#76074](https://github.com/kubernetes/kubernetes/pull/76074), [@danielqsj](https://github.com/danielqsj))

* kube-apiserver: the default `--endpoint-reconciler-type` is now `lease`. The `master-count` endpoint reconciler type is deprecated and will be removed in 1.13. ([#63383](https://github.com/kubernetes/kubernetes/pull/63383), [@liggitt](https://github.com/liggitt))

- Resolves a spurious "Unknown discovery response content-type" error in client-go discovery requests by tolerating extra content-type parameters in API responses ([#117637](https://github.com/kubernetes/kubernetes/pull/117637), [@seans3](https://github.com/seans3)) [SIG API Machinery]

- Removed attachable volume limits from the capacity of the node for the following
  volume type when the kubelet was started, affecting the following volume types
  when the corresponding csi driver was installed:
  - `awsElasticBlockStore` for `ebs.csi.aws.com`
  - `azureDisk` for `disk.csi.azure.com`

- Added a new `ServiceCIDR` type that allows to dynamically configure the cluster range used to allocate `Service ClusterIPs` addresses. ([#116516](https://github.com/kubernetes/kubernetes/pull/116516), [@aojea](https://github.com/aojea))
- Added a new `ipMode` field to the `.status` of Services where `type` is set to `LoadBalancer`.

* For x-kubernetes-list-type=set a scalar or atomic item type is now required, as documented. Persisted, invalid data is tolerated. ([#85385](https://github.com/kubernetes/kubernetes/pull/85385), [@sttts](https://github.com/sttts))
