- In kubelet configuration, the `.memorySwap.swapBehavior` field now accepts a new value `NoSwap`, which becomes the default if unspecified. The previously accepted `UnlimitedSwap` value has been dropped.

- Coordination.v1alpha1 API is dropped and replaced with coordination.v1alpha2. Old coordination.v1alpha1 types must be deleted before upgrade ([#127857](https://github.com/kubernetes/kubernetes/pull/127857), [@Jefftree](https://github.com/Jefftree)) [SIG API Machinery, Etcd, Scheduling...

* Fixed an issue with informers missing an `Added` event if a recently deleted object was immediately recreated at the same time the informer dropped a watch and relisted. ([#83911](https://github.com/kubernetes/kubernetes/pull/83911), [@matte21](https://github.com/matte21))

### Bug or Regression

- Bug Fix: Kube-proxy dropped endpointSlice's local endpoints when upgrading from 1.20 to 1.22 ([#110245](https://github.com/kubernetes/kubernetes/pull/110245), [@xh4n3](https://github.com/xh4n3)) [SIG Network]

* The Certificates API has graduated from alpha to beta. This is a backwards-incompatible change since the alpha support is dropped, and therefore kubeadm v1.5 and v1.6 don't work together (for example kubeadm v1.5 can't join a kubeadm v1.6 cluster).
* Supporting only etcd3, with 3.0.14 as the minimum version.
