* iSCSI sessions managed by kubernetes will now explicitly set startup.mode to 'manual' to  prevent automatic login after node failure recovery. This is the default open-iscsi mode, so this change will only impact users who have changed their startup.mode to be 'automatic' in /etc/iscsi/iscsid.conf.

from OkHttp 4.x:

**OkHttp is now packaged as separate JVM and Android artifacts.** This allows us to offer
platform-specific features and optimizations. If your build system handles [Gradle module metadata],
this change should be automatic.

**MockWebServer has a new coordinate and package name.** We didn’t like that our old artifact
depends on JUnit 4 so the new one doesn’t. It also has a better API built on immutable values. (We

## Urgent Upgrade Notes
### (No, really, you MUST read this before you upgrade)
#### Cluster Lifecycle
- Kubeadm: add a new `kubelet-finalize` phase as part of the `init` workflow and an experimental sub-phase to enable automatic kubelet client certificate rotation on primary control-plane nodes.

            final byte[] decryptionKey = Smb3KeyDerivation.deriveDecryptionKey(dialectInt, sessionKey, preauthHash);

            // Pass session key and preauthHash to enable automatic key rotation
            return new Smb2EncryptionContext(cipherId, dialect, encryptionKey, decryptionKey, sessionKey, preauthHash);

  - `apiserver_encryption_config_controller_automatic_reload_failures_total`: Total number of failed automatic reloads of encryption configuration.
  - `apiserver_encryption_config_controller_automatic_reload_success_total`: Total number of successful automatic reloads of encryption configuration.

    is 0 seconds. HTTP 408 (Client Timeout) responses are retried automatically
    if the header is absent or its delay is 0 seconds.
 *  New: Allow request bodies for all HTTP methods except GET and HEAD.
 *  New: Automatic module name of `okhttp3` for use with the Java Platform
    Module System.
 *  New: Log gzipped bodies when `HttpLoggingInterceptor` is used as a network
    interceptor.

- Kube-proxy: Added dual-stack IPv4/IPv6 support to the iptables proxier. ([#82462](https://github.com/kubernetes/kubernetes/pull/82462), [@vllry](https://github.com/vllry)) [SIG Network]
- Kubeadm now supports automatic calculations of dual-stack node cidr masks to kube-controller-manager. ([#85609](https://github.com/kubernetes/kubernetes/pull/85609), [@Arvinderpal](https://github.com/Arvinderpal)) [SIG Cluster Lifecycle]

- KMS: added validation for duplicate kms config name when auto reload is enabled. If you enabled automatic reload of encryption configuration with API server flag `--encryption-provider-config-automatic-reload`, ensure all the KMS provider names (v1 and v2) in the encryption configuration are unique. ([#113697](https://github.com/kubernetes/kubernetes/pull/113697), [@aramase](https://github.com/aramase))...

* kubeadm: preflight checks on external etcd certificates are now skipped when joining a control-plane node with automatic copy of cluster certificates (--certificate-key) ([#75847](https://github.com/kubernetes/kubernetes/pull/75847), [@fabriziopandini](https://github.com/fabriziopandini))
