* Included the list of security groups when failing with the errors that...

- Fixed mounting of iSCSI volumes over IPv6 networks. ([#110688](https://github.com/kubernetes/kubernetes/pull/110688), [@jsafrane](https://github.com/jsafrane))
- Fixed performance issue when creating large objects using SSA with fully unspecified schemas ( preserveUnknownFields ). ([#111557](https://github.com/kubernetes/kubernetes/pull/111557), [@alexzielenski](https://github.com/alexzielenski))

- The `StartupProbe` feature gate that is GA since v1.20 is unconditionally enabled, and can no longer be specified via the `--feature-gates` argument. ([#104168](https://github.com/kubernetes/kubernetes/pull/104168), [@ialid...

- Fix performance issue when creating large objects using SSA with fully unspecified schemas (preserveUnknownFields). ([#111915](https://github.com/kubernetes/kubernetes/pull/111915), [@aojea](https://github.com/aojea)) [SIG API Machinery, Architecture, Auth, CLI, Cloud Provider, Cluster Lifecycle, Instrumentation, Storage and Testing]...

- kube-proxy

  - the `--resource-container` flag has been removed from kube-proxy, and specifying it will now cause an error. The behavior is now as if you specified `--resource-container=""`. If you previously specified a non-empty `--resource-container`, you can no longer do so as of kubernetes 1.16. ([#78294](https://github.com/kubernetes/kubernetes/pull/78294), [@vllry](https://github.com/vllry))

- kube-scheduler

 - Kubeadm now respects user specified etcd versions in the ClusterConfiguration and properly uses them. If users do not want to stick to the version specified in the ClusterConfiguration, they should edit the kubeadm-config config map and delete it. ([#89588](https://github.com/kubernetes/kubernetes/pull/89588), [@rosti](https://github.com/rosti))...

* Fix issue with PodDisruptionBudgets in which `minAvailable` specified as a percentage did not work with StatefulSet Pods. ([#39454](https://github.com/kubernetes/kubernetes/pull/39454), [@foxish](https://github.com/foxish))

### Non-recursive Volume Ownership (FSGroup) graduates to Beta

By default, the `fsgroup` setting, if specified, recursively updates permissions for every file in a volume on every mount. This can make mount, and pod startup, very slow if the volume has many files. 

### Bug or Regression

- Fix memory leak on kube-scheduler preemption ([#111805](https://github.com/kubernetes/kubernetes/pull/111805), [@amewayne](https://github.com/amewayne)) [SIG Scheduling]
- If the parent directory of the file specified in the `--audit-log-path` argument does not exist, Kubernetes now creates it. ([#111227](https://github.com/kubernetes/kubernetes/pull/111227), [@vpnachev](https://github.com/vpnachev)) [SIG Auth]

  key in kubelet configuration. ([#112957](https://github.com/kubernetes/kubernetes/pull/112957), [@mxpv](https://github.com/mxpv)) [SIG API Machinery, Node, Scalability and Testing]
