will be enforced on all pods by default. To opt-out set
    `--enforce-node-allocatable=””`
  * Hard Eviction Thresholds will be subtracted from Capacity while calculating
    Node Allocatable. This will result in a reduction of schedulable capacity in
    clusters post upgrade where kubelet hard eviction has been turned on for
    memory. To opt-out set `--experimental-allocatable-ignore-eviction=true`.

- The deprecated flag `--hard-pod-affinity-symmetric-weight` and `--scheduler-name` have been removed from `kube-scheduler`. Use `ComponentConfig` instead to configure those parameters. ([#102805](https://github.com/kubernetes/kubernetes/pull/102805), [@ahg-g](https://github.com/ahg-g))...

* Filter duplicate network packets in promiscuous bridge mode (with ebtables) ([#28717](https://github.com/kubernetes/kubernetes/pull/28717), [@freehan](https://github.com/freehan))
* Refactor to simplify the hard-traveled path of the KubeletConfiguration object ([#29216](https://github.com/kubernetes/kubernetes/pull/29216), [@mtaufen](https://github.com/mtaufen))

SIG Network has graduated the widely used [Ingress API](https://kubernetes.io/docs/concepts/services-networking/ingress/) to general availability in Kubernetes 1.19. This change recognises years of hard work by Kubernetes contributors, and paves the way for further work on future networking APIs in Kubernetes.

### seccomp graduates to General Availability

* By default, --low-diskspace-threshold-mb is not set, and --eviction-hard includes "nodefs.available<10%,nodefs.inodesFree<5%" ([#46448](https://github.com/kubernetes/kubernetes/pull/46448), [@dashpole](https://github.com/dashpole))

- The `matchLabelKeys/mismatchLabelKeys` feature is introduced to the hard/soft `PodAffinity/PodAntiAffinity`. ([#116065](https://github.com/kubernetes/kubernetes/pull/116065), [@sanposhiho](https://github.com/sanposhiho))

- Kubernetes will now consume the AWS region list from the AWS SDK instead of a hard-coded list in the cloud provider. ([#75990](https://github.com/kubernetes/kubernetes/pull/75990), [@mcrute](https://github.com/mcrute))

* Remove deprecated flags: --low-diskspace-threshold-mb and --outofdisk-transition-frequency, which are replaced by --eviction-hard ([#48846](https://github.com/kubernetes/kubernetes/pull/48846), [@dashpole](https://github.com/dashpole))
