### SIG Storage

Over the last year, SIG Storage has been focused on adding support for the Container Storage Interface (CSI) to Kubernetes. The specification recently moved to 1.0, and on the heels of this achievement, Kubernetes v1.13 moves CSI support for PersistentVolumes to GA.

* Node affinity has moved from annotations to api fields in the pod spec.  Node affinity that is defined in the annotations will be ignored. ([#37299](https://github.com/kubernetes/kubernetes/pull/37299), [@rrati](https://github.com/rrati))

cluster security policies.

For the 1.8 release, SIG Auth focused on stablizing existing features that were introduced
in previous releases. RBAC was moved from beta to v1, and advanced auditing was moved from alpha
to beta. Encryption of resources stored on disk (resources at rest) remained in alpha, and the SIG began exploring integrations with external key management systems.

- TaintNodeByCondition has been moved to Beta and is enabled by default.
- Scheduler throughput has been improved by ~50% in large clusters (>2000 nodes).

  - The disk-cached discovery client is moved from k8s.io/client-go/discovery to k8s.io/client-go/discovery/cached/disk.
The memory-cached discovery client is moved from k8s.io/client-go/discovery/cached to k8s.io/client-go/discovery/cached/memory.

Maintainers of FlexVolume drivers should implement a CSI driver and move users of FlexVolume to CSI.
Users of FlexVolume should move their workloads to CSI driver.

### Deprecation of klog specific flags

enabled, you can create Services which can use IPv4, IPv6, or both, and you can change this setting for existing Services. Details are available in updated [IPv4/IPv6 dual-stack docs](https://docs.k8s.io/concepts/services-networking/dual-stack/), which cover the nuanced array of options.

We expect this implementation to progress from alpha to beta and GA in coming releases, so we’re eager to have you comment about your dual-stack experiences in [#k8s-dual-stack](https://kubernetes.slack.c...

* Default scheduler code is moved out of the plugin directory. ([#57852](https://github.com/kubernetes/kubernetes/pull/57852), [@misterikkit](https://github.com/misterikkit))

* CDK nginx ingress is now handled via a daemon set. ([#57530](https://github.com/kubernetes/kubernetes/pull/57530), [@hyperbolic2346](https://github.com/hyperbolic2346))

### **Multicluster**

*   Development of Kubernetes Federation has moved to [github.com/kubernetes/federation](https://github.com/kubernetes/federation). This move out of tree also means that Federation will begin releasing separately from Kubernetes. Impact:
    *   Federation-specific behavior will no longer be included in kubectl
