* adjusted http/2 buffer sizes for apiservers to prevent starvation issues between concurrent streams ([#67902](https://github.com/kubernetes/kubernetes/pull/67902), [@liggitt](https://github.com/liggitt))

- Add and update documentation.
- Add support to Manilla for provisioning existing shares.
- Add cluster name to load balancer description
- Add synchronization between Kubernetes and Keystone projects
- Add use internal DNS name for 'hostname' of nodes.
- Add support for CSI spec v0.3.0 for both Cinder and Manilla

  cluster with ECDSA certificates from "kubeadm init". Renewal of existing ECDSA certificates is also supported using "kubeadm alpha certs renew", but not switching between the RSA and ECDSA algorithms on the fly or during upgrades. ([#86953](https://github.com/kubernetes/kubernetes/pull/86953), [@rojkov](https://github.com/rojkov)) [SIG API Machinery, Auth and Cluster Lifecycle]

- Added driver-owned fields in `ResourceSlice` to mark whether the device was shareable among multiple resource claims (or requests) and to specify how each capacity could be shared between different requests.
  - Added user-owned fields in `ResourceClaim` to specify resource requirements against each device capacity.

### Other (Bug, Cleanup or Flake)

- Add delays between goroutines for vm instance update ([#88094](https://github.com/kubernetes/kubernetes/pull/88094), [@aramase](https://github.com/aramase)) [SIG Cloud Provider]

- Added a `--topology-manager-policy-options` flag to the kubelet to support fine tuning the topology manager policies. The first policy option, `prefer-closest-numa-nodes`, allows these policies to favor sets of NUMA nodes with shorter distance between nodes when making admission decisions. ([#112914](https://github.com/kubernetes/kubernetes/pull/112914), [@PiotrProkop](https://github.com/PiotrProkop))

- Added new config option `delayCacheUntilActive` to `KubeSchedulerConfiguration` that can provide a tradeoff between memory efficiency and scheduling speed when their leadership is updated in `kube-scheduler` ([#115754](https://github.com/kubernetes/kubernetes/pull/115754), [@linxiulei](https://github.com/linxiulei)) [SIG API Machinery and Scheduling]
