#### Defaults

 - The default spec.updateStrategy for the StatefulSet and DaemonSet kinds is
 RollingUpdate for the apps/v1beta2 group version. You can explicitly set
 the OnDelete strategy, and no strategy auto-conversion is applied to
 replace default values.

 - As mentioned in [Behavioral Changes](#behavioral-changes), selector
 defaults are disabled.

- Added a `.status.features.supplementalGroupsPolicy`...

* Add generic Toleration for NoExecute Taints to NodeProblemDetector ([#45883](https://github.com/kubernetes/kubernetes/pull/45883), [@gmarek](https://github.com/gmarek))
* support replaceKeys patch strategy and directive for strategic merge patch ([#44597](https://github.com/kubernetes/kubernetes/pull/44597), [@mengqiy](https://github.com/mengqiy))

## Changes by Kind

### Bug or Regression

- Fixes a regression in 1.27.0 that resulted in "missing metadata in converted object" errors when modifying objects for multi-version custom resource definitions with a conversion strategy of `None`. ([#117305](https://github.com/kubernetes/kubernetes/pull/117305), [@ncdc](https://github.com/ncdc)) [SIG API Machinery]

- CustomResourceDefinition schemas that use `x-kubernetes-list-type: map` or `x-kubernetes-list-type:...

### SIG-ibmcloud

As a newly created SIG, the SIG-ibmcloud has mainly focused on SIG set up, sharing IBM Clouds ongoing Kubernetes work like scalability tests, Kubernetes upgrade strategy etc. with the SIG members and start working on processes to move cloud provider code to a public GitHub repo.

### SIG-instrumentation

### SIG CLI

- `kubectl apply` can now change a deployment strategy from rollout to recreate without explicitly clearing the rollout-related fields ([#70436](https://github.com/kubernetes/kubernetes/pull/70436), [@liggitt](https://github.com/liggitt))

- resource.k8s.io/ResourceClaim (alpha API): The strategic merge patch strategy for the `status.reservedFor` array was changed so that a strategic-merge-patch can now add individual entries. This change may break clients using strategic merge patch to update status, which rely on the previous behavior (replacing the entire array).

* fluentd will tolerate all NoExecute Taints when run in gcp configuration. ([#45715](https://github.com/kubernetes/kubernetes/pull/45715), [@gmarek](https://github.com/gmarek))
* Fix [Deployments with Recreate strategy not waiting for Pod termination](https://github.com/kubernetes/kubernetes/issues/27362). ([#45639](https://github.com/kubernetes/kubernetes/pull/45639), [@ChipmunkV](https://github.com/ChipmunkV))

* Fix StatefulSet to work correctly with set-based selectors. ([#59365](https://github.com/kubernetes/kubernetes/pull/59365), [@ayushpateria](https://github.com/ayushpateria))

* Fixes a case when Deployment with recreate strategy could get stuck on old failed Pod. ([#60301](https://github.com/kubernetes/kubernetes/pull/60301), [@tnozicka](https://github.com/tnozicka))
