* Laid the groundwork for OIDC distributed claims handling in the apiserver authentication token checker. A distributed claim allows the OIDC provider to delegate a claim to a separate URL. ([ref](http://openid.net/specs/openid-connect-core-1_0.html#AggregatedDistributedClaims)). ([#63213](https://github.com/kubernetes/kubernetes/pull/63213), [@filmil](https://github.com/filmil))

- Kubeadm: make sure that `kubeadm init/join` always use a URL scheme (unix:// on Linux and npipe:// on Windows) when passing a value to the `--container-runtime-endpoint` kubelet flag. This flag's value is taken from the kubeadm configuration `criSocket` field or the `--cri-socket` CLI flag. Automatically add a missing URL scheme to the user configuration in memory, but warn them that they should also update their configuration on disk manually....

*   It is now possible to set multiple manifest URL headers with the kubelet's `--manifest-url-header` flag. Multiple headers for the same key will be added in the order provided. The ManifestURLHeader field in KubeletConfiguration object (kubeletconfig/v1alpha1) is now a map[string][]string, which facilitates writing JSON...

- Kubeadm: external etcd endpoints passed in the `ClusterConfiguration` that have Unicode characters are no longer IDNA encoded (converted to Punycode). They are now just URL encoded as per Go's implementation of RFC-3986, have duplicate "/" removed from the URL paths, and passed like that directly to the `kube-apiserver` `--etcd-servers` flag. If you have etcd endpoints that have Unicode characters, it is advisable to encode them in advance with tooling that is fully...

- If the user specifies an invalid timeout in the request URL, the request will be aborted with an HTTP 400.

  - https://github.com/kubernetes-sigs/kustomize/pull/4985: If you previously included .git in an AWS or Azure URL, we will no longer automatically remove that suffix. You may need to add an extra / to replace the .git for the URL to properly resolve.

### CVE-2022-3172: Aggregated API server can cause clients to be redirected (SSRF)

A security issue was discovered in kube-apiserver that could allow an attacker controlled aggregated API server to redirect client traffic to any URL.  This could lead to the client performing unexpected actions as well as leaking the client's credentials to third parties.
