### SIG Scalability

## Changelog since v1.6.8

### Other notable changes

* StatefulSet: Set hostname/subdomain fields on new Pods in addition to the deprecated annotations, to allow mitigation of Pod DNS issues upon upgrading to Kubernetes v1.7.x. ([#50942](https://github.com/kubernetes/kubernetes/pull/50942), [@enisoc](https://github.com/enisoc))

- Kubelet: Extended the `--image-credential-provider-config` flag to accept a directory path in addition to a single file. When a directory was specified, all .json, .yaml, and .yml files in that directory were loaded and merged in lexicographical order. ([#131658](https://github.com/kubernetes/kubernetes/pull/131658), [@dims](https://github.com/dims))...

SIG Windows is also including several addition to this release:
 - Direct Server Return (DSR) mode support, allowing large numbers of services to scale up efficiently
 - Windows containers  now honor CPU limits

  - example manifests for the kube-apiserver, kube-controller-manager, kube-schedule, kubelet, and the cloud-controller-manager
  - labels/annotations that are consumed by any cloud specific controllers

In addition to the above, SIG Cloud Provider has been focusing on a long running effort to remove cloud provider code from kubernetes/kubernetes.

### SIG-cluster-lifecycle

            automatic inclusion of the build profile. Multiple conditions can be defined, which must
            be all satisfied to activate the profile.

            <p>In addition to the traditional activation mechanisms (JDK version, OS properties,
            file existence, etc.), Maven now supports a powerful condition-based activation

  `Speak English!' said the Eaglet.  `I don't know the meaning of
half those long words, and, what's more, I don't believe you do

  - [beta] `kube-apiserver` now publishes a swagger 2.0 spec in addition to a swagger 1.2 spec ([kubernetes/features#53](https://github.com/kubernetes/enhancements/issues/53))

* In order to bypass graceful deletion of pods (to immediately remove the pod from the API) the user must now provide the `--force` flag in addition to `--grace-period=0`.  This prevents users from accidentally force deleting pods without being aware of the consequences of force deletion.  Force deleting pods for resources like StatefulSets can result in multiple pods with the same name having...

Note that snapshot support will require Kubernetes distributors to bundle the Snapshot controller, Snapshot CRDs, and validation webhook. In addition, a CSI driver supporting the snapshot functionality must also be deployed on the cluster.
