-  Remove already deprecated options `resyncperiod` and `upstream` in the Kubernetes plugin.
  -  Includes Prometheus metrics name changes (to bring them in line with standard Prometheus metrics naming convention). They will be backward incompatible with existing reporting formulas that use the old metrics' names.
  -  The federation plugin (allows for v1 Kubernetes federation) has been removed.

  CVE-2021-29923 golang standard library "net" - Improper Input Validation of octal literals in golang 1.16.2 and below standard library "net" results in indeterminate SSRF & RFI vulnerabilities.

### CSI Volume Snapshot graduates to General Availability

CSI Volume Snapshot moves to GA in the 1.20 release. This feature provides a standard way to trigger volume snapshot operations in Kubernetes and allows Kubernetes users to incorporate snapshot operations in a portable manner on any Kubernetes environment regardless of supporting underlying storage providers.

### Cloud Provider

- When a load balancer type service is created in a k8s cluster that is backed by Azure Standard Load Balancer, the corresponding load balancer rule added in the Azure Standard Load Balancer would now have the "EnableTcpReset" property set to true. ([#80624](https://github.com/kubernetes/kubernetes/pull/80624), [@xuto2](https://github.com/xuto2))

- Exec plugin authors can override default handling of standard input via new `interactiveMode` kubeconfig field. ([#99310](https://github.com/kubernetes/kubernetes/pull/99310), [@ankeesler](https://github.com/ankeesler))

* Fix nil pointer dereference in azure cloud provider ([#85975](https://github.com/kubernetes/kubernetes/pull/85975), [@ldx](https://github.com/ldx))
* fix: azure disk could not mounted on Standard_DC4s/DC2s instances ([#86612](https://github.com/kubernetes/kubernetes/pull/86612), [@andyzhangx](https://github.com/andyzhangx))

    The plugins are being updated to resolve this issue ([#43488](https://github.com/kubernetes/kubernetes/issues/43488)).
    You can disable CRI explicitly (`--enable-cri=false`) as a
    temporary workaround.
      * The standard `bridge` plugin have been validated to interoperate with
         the new CRI + CNI code path.
      * If you are using plugins other than `bridge`, make sure you have

- Text logging in Kubernetes components now uses [textlogger](https://pkg.go.dev...

- Added the same information to an init container as a standard container in a pod when using `PodPresets`. ([#71479](https://github.com/kubernetes/kubernetes/pull/71479), [@soggiest](https://github.com/soggiest))

- Added `UserNamespacesPodSecurityStandards` feature gate to enable user namespace support for Pod Security Standards.
  Enabling this feature will modify all Pod Security Standard rules to allow setting: `spec[.*].securityContext.[runAsNonRoot,runAsUser]`.
  This feature gate should only be enabled if all nodes in the cluster support the user namespace feature and have it enabled.
