* The old dynamic client has been replaced by a new one.  The previous dynamic client will exist for one release in `client-go/deprecated-dynamic`.  Switch as soon as possible. ([#63446](https://github.com/kubernetes/kubernetes/pull/63446), [@deads2k](https://github.com/deads2k))

- PersistentVolumeClaim objects are no longer left with storage class set to `nil` forever, but will be updated retroactively once any StorageClass is set or created as default. ([#...

- For raw block CSI volumes on Kubernetes, kubelet was incorrectly calling CSI NodeStageVolume for every single "map" (i.e. raw block "mount") operation for a volume already attached to the node. This PR ensures it is only called once per volume per node.

- Kubeadm: removed the restriction that the `ca.crt` can only contain one certificate. If there is more than one certificate in the `ca.crt` file, kubeadm will pick the first one by default. ([#107327](https://github.com/kubernetes/kubernetes/pull/107327), [@SataQiu](https://github.com/SataQiu))

  - the `--cloud-provider-gce-lb-src-cidrs` flag has been deprecated. This flag will be removed once the GCE Cloud Provider is removed from kube-apiserver. ([#81094](https://github.com/kubernetes/kubernetes/pull/81094), [@andrewsykim](https://github.com/andrewsykim))

  - `--service-account-issuer`, should be set to a URL identifying the API server that will be stable over the cluster lifetime.
  - `--service-account-key-file`, set to one or more files containing one or more public keys used to verify tokens.

- Client-go: fix that paged list calls with ResourceVersionMatch set would fail once paging kicked in. ([#107335](https://github.com/kubernetes/kubernetes/pull/107335), [@fasaxc](https://github.com/fasaxc)) [SIG API Machinery]

### Autoscaling

- Horizontal Pod Autoscaling can now scale targets up even when one or more metrics are invalid/unavailable, as long as one metric indicates a scale up should occur. ([#78503](https://github.com/kubernetes/kubernetes/pull/78503), [@gjtempleton](https://github.com/gjtempleton))


### AWS

* Run one etcd storage compaction per default interval of 5min. Do not run one for each resource and each CRD. This fixes the compaction log spam and reduces load on etcd. ([#68557](https://github.com/kubernetes/kubernetes/pull/68557), [@sttts](https://github.com/sttts))

  * Previously this would cause the command to fail regardless of whether or not the field was present in the object model
  * Now the command will succeed even if the sort-by field is missing from one or more of the objects
