### **Network**

#### **IPv6**

*   [alpha] IPv6 support has been added. Notable IPv6 support details include:
    *   Support for IPv6-only Kubernetes cluster deployments. **<span style="text-decoration:underline;">Note:</span>** This feature does not provide dual-stack support.
    *   Support for IPv6 Kubernetes control and data planes.
    *   Support for Kubernetes IPv6 cluster deployments using kubeadm.

* gitRepo volumes in pods no longer require git 1.8.5 or newer; older git versions are now supported. ([#62394](https://github.com/kubernetes/kubernetes/pull/62394), [@jsafrane](https://github.com/jsafrane))

  To request this behavior, your client software must enable the `WatchListClient` client-go feature gate. Additionally, streaming is only available if supported by the cluster; the API server that you connect to must also support streaming.

    * Force drain to use delete, even if eviction is supported. This will bypass checking PodDisruptionBudgets, and should be used with caution.
* kubeadm now errors out whenever a not supported component config version is supplied for the kubelet and kube-proxy ([#85639](https://github.com/kubernetes/kubernetes/pull/85639), [@rosti](https://github.com/rosti))

- StatefulSet is supported in `kubectl autoscale` command ([#71103](https://github.com/kubernetes/kubernetes/pull/71103), [@Pingan2017](https://github.com/Pingan2017))

- Add support support to Manilla for trustee authentication and supplying custom CAs.
- 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

* Docker versions 1.10.3, 1.11.2, 1.12.6 have been validated
  * Docker version 1.12.6 known issues
    * overlay2 driver not fully supported
    * live-restore not fully supported
    * no shared pid namespace support
  * Docker version 1.11.2 known issues
    * Kernel crash with Aufs storage driver on Debian Jessie ([#27885](https://github.com/kubernetes/kubernetes/issues/27885))

## Changes by Kind

### API Change

- DRA: the v1alpha4 kubelet gRPC API (added in 1.31, superseded in 1.32) is no longer supported. DRA drivers using the helper package from Kubernetes  >= 1.32 use the v1beta1 API and continue to be supported. ([#132574](https://github.com/kubernetes/kubernetes/pull/132574), [@pohly](https://github.com/pohly)) [SIG Node]

  * [alpha] CRI now supports specifying the GID of the container at both LinuxSandboxSecurityContext and LinuxContainerSecurityContext in addition to specifying the UID. Support is implemented for dockershim. [@krmayankk]

- Creation of new `CronJob` objects containing `TZ` or `CRON_TZ` in `.spec.schedule`, accidentally enabled in `v1.22`, is now disallowed. Use the `.spec.timeZone` field instead, supported in `v1.25+` clusters in default configurations. See https://kubernetes.io/docs/concepts/workloads/controllers/cron-jobs/#unsupported-timezone-specification for more information.
