The SIG also provided match criteria that allow policy rules to match a source or destination CIDR. Both features are in beta. SIG Network also improved the kube-proxy to include an alpha IPVS mode in addition to the current iptables and userspace modes.

ers/), it became more obvious how we can support developers with tooling built on top of `kubectl exec`. The addition of the `kubectl debug` [command](https://github.com/kubernetes/enhancements/blob/master/keps/sig-cli/1441-kubectl-debug/README.md) (it is alpha but your feedback is more than welcome), allows developers to easily debug their Pods inside the cluster. We think this addition is invaluable.  This command allows one to create a temporary container which runs next to the Pod one is trying...

- Kube-apiserver: multiple comma-separated protocols in a single X-Stream-Protocol-Version header are now recognized, in addition to multiple headers, complying with RFC2616 ([#89857](https://github.com/kubernetes/kubernetes/pull/89857), [@tedyu](https://github.com/tedyu)) [SIG API Machinery]

  - 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.

- `kube-proxy` in iptables mode will now have separate `sync_full_proxy_rules_duration_seconds`\nand
  `sync_partial_proxy_rules_duration_seconds` (in addition to the existing\n`sync_proxy_rules_duration_seconds`),
  giving better information about the duration of each \nsync type, rather than

In addition, support for NVMe disks has been added to Kubernetes, and a service of type LoadBalancer can now be backed with an NLB instead of an ELB (alpha).

Windows](https://github.com/kubernetes/kubernetes/pull/60275).) [Local Ephemeral Storage Capacity Isolation](https://github.com/kubernetes/enhancements/issues/361) makes it possible to set requests and limits on ephemeral local storage resources. In addition, you can now create [Local Persistent Storage](https://github.com/kubernetes/enhancements/issues/121), which enables PersistentVolumes to be created with locally attached disks, and not just network volumes.

On the Persistent Volumes...

- `kubectl exec` and `kubectl attach` now honor the `--quiet` flag which suppresses output from the local binary that could be confused by a script with the remote command output (all non-failure output is hidden). In addition, print inline with exec and attach the list of alternate containers when we default to the first spec.container.

SIG Cloud Provider has been focused on stabilizing the common APIs and interfaces consumed by cloud providers today. This involved auditing the cloud provider APIs for anything that should be deprecated as well as adding changes where necessary. In addition, SIG Cloud Provider has begun exploratory work around having a “cloud provider” e2e test suite which can be used to test common cloud provider functionalities with resources such as nodes and load balancers.

We are also continuing our...

disallow updates to all fields other than `.status` (not just `.spec` and `.metadata` as before). Also, `required` and `description` can be used at the root of the CRD OpenAPI validation schema when the `/status` subresource is enabled.

In addition, users can now create multiple versions of CustomResourceDefinitions, but without any kind of automatic conversion, and CustomResourceDefinitions now allow specification of additional columns for `kubectl get` output via the `spec.additionalPrinterColumns`...
