  - `spec.scope` is no longer defaulted to `Namespaced` and must be explicitly specified
  - `spec.version` is removed in v1; use `spec.versions` instead
  - `spec.validation` is removed in v1; use `spec.versions[*].schema` instead
  - `spec.subresources` is removed in v1; use `spec.versions[*].subresources` instead
  - `spec.additionalPrinterColumns` is removed in v1; use `spec.versions[*].additionalPrinterColumns` instead

#### Behavioral Changes

 - For all kinds in the API group version, a spec.selector default value is no longer
 available, because it's incompatible with `kubectl
 apply` and strategic merge patch. You must explicitly set the spec.selector value
 in your manifest. An object with a spec.selector value that does not match the labels in
 its spec.template is invalid.

 - Selector mutation is disabled for all kinds in the

  - If the custom resource participates the spec/status convention, the metadata.generation of the CR increments when there is any change, except for the changes to the metadata or the changes to the status.
  - If the custom resource does not participate the spec/status convention, the metadata.generation of the CR increments when there is any change to the CR, except for changes to the metadata.

- Pods which have an invalid negative `spec.terminationGracePeriodSeconds` value will be treated as having terminationGracePeriodSeconds of 1 ([#115606](https://github.com/kubernetes/kubernetes/pull/115606), [@wzshiming](https://github.com/wzshiming)) [SIG Apps, Node and Testing]

- Setting the `status.loadBalancer` of a Service whose `spec.type` is not `LoadBalancer` was previously allowed, but any update to the `metadata` or `spec` would wipe that field. Setting this field is no longer permitted unless `spec.type` is  `LoadBalancer`.  In the very unlikely event that this has unexpected impact, you can enable the `AllowServiceLBStatusOnNonLB` feature gate, which will restore...

- When using `kubectl replace` (or the equivalent API call) on a Service, the caller no longer needs to do a read-modify-write cycle to fetch the allocated values for `.spec.clusterIP` and `.spec.ports[].nodePort`.  Instead the API server will automatically carry these forward from the original object when the new object does not specify them.

* The `spec.SecurityContext.Sysctls` field is now dropped during creation of `Pod` objects unless the `Sysctls` feature gate is enabled. ([#72752](https://github.com/kubernetes/kubernetes/pull/72752), [@rajathagasthya](https://github.com/rajathagasthya))
