## Major Themes

Kubernetes is developed by community members whose work is organized into
[Special Interest Groups][]. For the 1.8 release, each SIG provides the
themes that guided their work.

### SIG VMWare

Major focus for SIG VMware for this release is the work on moving internal APIs that the vSphere provider depends upon to staging to guarantee API stability. This work is being done in conjunction with SIG Cloud Provider and includes the creation of a brand new vsphere-csi plugin to replace the current volume functionalities in-tree.

### Network

In v1.9 SIG Network has implemented alpha support for IPv6, and alpha support for CoreDNS as a drop-in replacement for kube-dns. Additionally, SIG Network has begun the deprecation process for the extensions/v1beta1 NetworkPolicy API in favor of the networking.k8s.io/v1 equivalent.

### Node

- kubeadm: Added preflight check for `cp` on Linux nodes and `xcopy` on Windows nodes. These binaries are required for kubeadm to work properly. ([#130045](https://github.com/kubernetes/kubernetes/pull/130045), [@carlory](https://github.com/carlory))...

  - Migrate interaction with the API from using internal types to using Unstructured
  - Improve tests to work better with constrained resources
  - Add support for node autodiscovery
  - Add support for `--cloud-config`
  - Update group identifier to use for Cluster API annotations
  
  ### Exoscale
  - Add support for Exoscale
  
  ### GCE
  - Decrease the number of GCE Read Requests made while deleting nodes

Major features for stateful applications include automated updates to StatefulSets, enhanced updates for DaemonSets, a burst mode for faster StatefulSets scaling, and (alpha) support for local storage.

- Fixed `kubectl explain` to show enum for field types if they were defined. ([#123023](https://github.com/kubernetes/kubernetes/pull/123023), [@ah8ad3](https://github.com/ah8ad3))

configuration file, that gets forwarded to kubelet static pods to control pull policy for etcd and control plane images. This option allows for precise image pull policy specification for master nodes and thus for more tight control over images. It is useful in CI environments and in environments, where the user has total control over master VM templates (thus, the master VM templates can be preloaded with the required Docker images for the control plane services).
