### SIG Windows

- Kubelet no longer attempts to sync iptables on non-Linux systems.. ([#67690](https://github.com/kubernetes/kubernetes/pull/67690), [@feiskyer](https://github.com/feiskyer))
- Kubelet no longer applies default hard evictions of nodefs.inodesFree on non-Linux systems. ([#67709](https://github.com/kubernetes/kubernetes/pull/67709), [@feiskyer](https://github.com/feiskyer))

* 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))

  - [beta] Kubelet integrates with memcg notification API to detect when a hard eviction threshold is crossed ([kubernetes/features#125](https://github.com/kubernetes/enhancements/issues/125))

- 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))...

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

- UDP and SCTP protocols can left stale connections that need to be cleared to avoid services disruption, but they can cause problems that are hard to debug.

### Promoted core CSI Migration to Stable

- Modified command line errors (for example, `kubectl list` -> `unknown command`) that were printed as log message with escaped line breaks instead of a multi-line plain text, making the error hard to read. ([#107044](https://github.com/kubernetes/kubernetes/pull/107044), [@pohly](https://github.com/pohly))

addition, we’ve introduced a new “soft” kind of node selector that is just a
hint to the scheduler; the scheduler will try to satisfy these requests but it
does not guarantee they will be satisfied. Both the “hard” and “soft” variants
