- Easier to understand a cluster (eg: API audit logs, server-based API defaults)
- **Stateful Application Support**
  - Enhanced persistence capabilities (eg: `StorageClasses`, new volume plugins)
  - New resources and scheduler features (eg: `ScheduledJob` resource, pod/node affinity/anti-affinity)
- **Cluster Federation**

  validate any input config file. Use the `--config` flag to pass a config file
  to it. See the command `--help` screen for more information. As a result of adding
  this new command, enhance the validation capabilities of the existing "kubeadm
  config migrate" command. For both commands unknown APIs or fields will throw errors. ([#118013](https://github.com/kubernetes/kubernetes/pull/118013), [@neolit123](https://github.com/neolit123))

- Support for out of tree networking with Azure-CNI, OVN-Kubernetes and Flannel
- Improved support for pods, service types, workload controllers and metrics/quotas to closely match the capabilities offered for Linux containers

  honor the specified `scheme` and `headers` fields. This enables setting custom
  headers and changing the scheme to `HTTPS`, consistent with container
  startup/readiness/liveness probe capabilities. Lifecycle handlers configured
  with `scheme: HTTPS` that encounter errors indicating the endpoint is actually
  using HTTP fall back to making the request over HTTP for compatibility with

*   Added warmup capabilities to `tf.keras.optimizers.schedules.CosineDecay` learning rate scheduler. You can now specify an initial and target learning rate, and our scheduler will perform a linear interpolation between the two after which it will begin a decay phase.

- The Kubelet's `--experimental-mounter-path` and `--experimental-check-node-capabilities-before-mount` options are now marked as deprecated. ([#91373](https://github.com/kubernetes/kubernetes/pull/91373), [@knabben](https://github.com/knabben))

* vSphere cloud provider: Allow specifying fstype in storage class. ([#41929](https://github.com/kubernetes/kubernetes/pull/41929), [@abrarshivani](https://github.com/abrarshivani))
* vSphere cloud provider: Allow specifying VSAN Storage Capabilities during dynamic volume provisioning. ([#42974](https://github.com/kubernetes/kubernetes/pull/42974), [@BaluDontu](https://github.com/BaluDontu))



# v1.6.2

#### Audit Logging
* [alpha] Advanced Auditing enhances the Kubernetes API [audit logging](https://kubernetes.io/docs/tasks/debug/debug-cluster/audit/#log-backend) capabilities through a customizable policy, pluggable audit backends, and richer audit data.

#### Encryption at Rest

* Added a new `kubeadm upgrade node config` command. ([#64624](https://github.com/kubernetes/kubernetes/pull/64624), [@luxas](https://github.com/luxas))
* kubeadm now makes the CoreDNS container more secure by dropping (root) capabilities and improves the integrity of the container by running the whole container in read-only.  ([#64473](https://github.com/kubernetes/kubernetes/pull/64473), [@nberlee](https://github.com/nberlee))
