`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 the previous behavior.  If you do need to set this, please file an issue with the Kubernetes project to help contributors understand...

- For Dynamic Resource Allocation, labels in node selectors now are validated. Invalid labels already caused runtime errors before and are unlikely to occur in practice. ([#128932](https://github.com/kubernetes/kubernetes/pull/128932), [@pohly](https://github.com/pohly))

- A small regression in Service updates was fixed. The circumstances are so unlikely that probably nobody would ever hit it. ([#104601](https://github.com/kubernetes/kubernetes/pull/104601), [@thockin](https://github.com/thockin))

- Ensure Job status updates are batched by 1s. This fixes an unlikely scenario when a sequence of immediately 
  completing pods could trigger a sequence of non-batched Job status updates. ([#118470](https://github.com/kubernetes/kubernetes/pull/118470), [@mimowo](https://github.com/mimowo)) [SIG Apps]

- Dynamic Resource Allocation (DRA): fixed some small, unlikely race condition during pod scheduling. ([#124595](https://github.com/kubernetes/kubernetes/pull/124595), [@pohly](https://github.com/pohly)) [SIG Node, Scheduling and Testing]

 app/v1beta2 group version, because the controllers in the workloads API do not handle
 selector mutation in
 a consistent way. This restriction may be lifted in the future, but
 it is likely that that selectors will remain immutable after the move to v1.
 You can continue to use code that depends on mutable selectors by calling
 the apps/v1beta1 API in this release, but you should start planning for code

  CIDR values (like "192.168.000.005", which should not have the extra zeros).
  Values with non-standard formats can introduce security problems, and will
  likely be forbidden in a future Kubernetes release. ([#128786](https://github.com/kubernetes/kubernetes/pull/128786), [@danwinship](https://github.com/danwinship)) [SIG Apps, Network and Node]
