### **Network**

*   NetworkPolicy objects are now stored in etcd in v1 format. After you upgrade to version 1.9, make sure that all NetworkPolicy objects are migrated to v1. ([#51955](https://github.com/kubernetes/kubernetes/pull/51955), [@danwinship](https://github.com/danwinship))

- Fixed "requested device X but found Y" attach error on AWS. ([#85675](https://github.com/kubernetes/kubernetes/pull/85675), [@jsafrane](https://github.com/jsafrane)) [SIG Cloud Provider and Storage]
- Fixed NetworkPolicy validation that `Except` values are accepted when they are outside the CIDR range. ([#86578](https://github.com/kubernetes/kubernetes/pull/86578), [@tnqn](https://github.com/tnqn)) [SIG Network]

* When using Role-Based Access Control, the "admin", "edit", and "view" roles now have the expected permissions on NetworkPolicy resources, rather than reserving those permissions to only cluster-admin. ([#56650](https://github.com/kubernetes/kubernetes/pull/56650), [@danwinship](https://github.com/danwinship))

- Adds support for endPort field in NetworkPolicy ([#97058](https://github.com/kubernetes/kubernetes/pull/97058), [@rikatz](https://github.com/rikatz)) [SIG Apps and Network]

    * Trigger pod eviction when available memory falls below 100Mi.
* Enable extensions/v1beta1/NetworkPolicy by default ([#28549](https://github.com/kubernetes/kubernetes/pull/28549), [@caseydavenport](https://github.com/caseydavenport))

- Fixed a bug where `kubectl describe` incorrectly displayed NetworkPolicy port ranges
  (showing only the starting port). ([#123316](https://github.com/kubernetes/kubernetes/pull/123316), [@jcaamano](https://github.com/jcaamano))
- Fixed a bug where hard evictions due to resource pressure allowed pods

- SCTP is now supported as an additional protocol (alpha) alongside TCP and UDP in Pod, Service, Endpoint, and NetworkPolicy.

- NetworkPolicy validation framework support for windows. ([#98077](https://github.com/kubernetes/kubernetes/pull/98077), [@jayunit100](https://github.com/jayunit100))

- SCTP support in API objects (Pod, Service, NetworkPolicy) is now GA.
  Note that this has no effect on whether SCTP is enabled on nodes at the kernel level,

  - NetworkPolicy resources will no longer be served from `extensions/v1beta1` in v1.16. Migrate use to the `networking.k8s.io/v1` API, available since v1.8. Existing persisted data can be retrieved via the `networking.k8s.io/v1` API.
