- Added full cgroup v2 swap support for both `Limited` and `Unlimited` swap.
  
  When `LimitedSwap` is enabled the swap limit would be automatically calculated for
  Burstable QoS pods. For Best-Effort/Guaranteed QoS pods, swap would be disabled.
  
  Containers with memory requests equal to their memory limits also won't have
  swap access, and it is a way to opt-out of swap for a single container.
  

## Before Upgrading

Consider the following changes, limitations, and guidelines before you upgrade:

* The kubelet now fails if swap is enabled on a node. To override the default and run with /proc/swaps on, set `--fail-swap-on=false`. The experimental flag `--experimental-fail-swap-on` is deprecated in this release, and will be removed in a future release.

* kubeadm now produces error during preflight checks if swap is enabled. Users, who can setup kubelet to run in unsupported environment with enabled swap, will be able to skip that preflight check. ([#55399](https://github.com/kubernetes/kubernetes/pull/55399), [@kad](https://github.com/kad))

* StatefulSet in apps/v1 is now included in Conformance Tests. ([#60336](https://github.com/kubernetes/kubernetes/pull/60336), [@enisoc](https://github.com/enisoc))

* dockertools: disable memory swap on Linux. ([#59404](https://github.com/kubernetes/kubernetes/pull/59404), [@ohmystack](https://github.com/ohmystack))

### Kubernetes Node system swap support

Every system administrator or Kubernetes user has been in the same boat regarding setting up and using Kubernetes: disable swap space. With the release of Kubernetes 1.22, *alpha* support is available to run nodes with swap memory. This change lets administrators opt in to configuring swap on Linux nodes, treating a portion of block storage as additional virtual memory.

- Kubeadm: switch the preflight check (called 'Swap') that verifies if swap is enabled on Linux hosts to report a warning instead of an error. This is related to the graduation of the NodeSwap feature gate in the kubelet to Beta and being enabled by default in 1.23 - allows swap support on Linux hosts. In the next release of kubeadm (1.24) the preflight check will be removed, thus we recommend that you stop using...
