For the 1.8 release, SIG Network enhanced the NetworkPolicy API to support pod egress traffic policies.
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.

#### **Kubectl**

*   `kubectl cp` can now copy a remote file into a local directory. ([#46762](https://github.com/kubernetes/kubernetes/pull/46762),[ @bruceauyeung](https://github.com/bruceauyeung))
*   `kubectl cp` now honors destination names for directories. A complete directory is now copied; in previous versions only the file contents were copied. ([#51215](https://github.com/kubernetes/kubernetes/pull/51215),[ @juanvallejo](https://github.com/juanvallejo))

  - Make `build-in-docker` and `test-in-docker` work on Linux systems with SELinux enabled
  - Fix an error where existing nodes were not considered as destinations while finding place for pods in scale-down simulations
  - Remove redundant log lines and reduce severity around parsing kubeEnv
  - Don't treat nodes created by virtual kubelet as nodes from non-autoscaled node groups

* kubectl cp now safely allows unpacking of symlinks that may point outside the destination directory ([#82384](https://github.com/kubernetes/kubernetes/pull/82384), [@tallclair](https://github.com/tallclair))

* CRI now defines mounting behavior. If the host path doesn't exist, the runtime should return an error. If the host path is a symlink, the runtime should follow the symlink and mount the real destination to the container. ([#61460](https://github.com/kubernetes/kubernetes/pull/61460), [@feiskyer](https://github.com/feiskyer))

### SIG OpenStack

* kubectl cp now safely allows unpacking of symlinks that may point outside the destination directory ([#82384](https://github.com/kubernetes/kubernetes/pull/82384), [@tallclair](https://github.com/tallclair))

- Fixed cost estimation of token creation request for service account in Priority and Fairness. ([#113206](https://github.com/kubernetes/kubernetes/pull/113206), [@marseel](https://github.com/marseel))

* kubectl cp now safely allows unpacking of symlinks that may point outside the destination directory ([#82384](https://github.com/kubernetes/kubernetes/pull/82384), [@tallclair](https://github.com/tallclair))

    * Switches to use the eviction sub-resource instead of deletion in kubectl drain, if server supports.
* azure: load balancer preserves destination ip address ([#36256](https://github.com/kubernetes/kubernetes/pull/36256), [@colemickens](https://github.com/colemickens))

- Added the latest GCE pinhole firewall feature, which introduces `destination-ranges` in the ingress `firewall-rules`. It restricts access to the backend IPs by allowing traffic through `ILB` or `NetLB` only. This change does **NOT** change the existing `ILB` or `NetLB` behavior.
