- Fix performance issue when creating large objects using SSA with fully unspecified schemas (preserveUnknownFields).

- Finalizer Protection for Service LoadBalancers is now in GA (enabled by default). This feature ensures the Service resource is not fully deleted until the correlating load balancer resources are deleted. ([#85023](https://github.com/kubernetes/kubernetes/pull/85023), [@MrHohn](https://github.com/MrHohn))

* kube-apiserver: the `Priority` admission plugin is now enabled by default when using `--enable-admission-plugins`. If using `--admission-control` to fully specify the set of admission plugins, the `Priority` admission plugin should be added if using the `PodPriority` feature, which is enabled by default in 1.11.

- Finalizer Protection for Service LoadBalancers is now in beta (enabled by default). This feature ensures the Service resource is not fully deleted until the correlating load balancer resources are deleted.

            A universally unique identifier for a project. It is normal to
            use a fully-qualified package name to distinguish it from other
            projects with a similar name (eg. {@code org.apache.maven}).

The Cluster API effort is currently undergoing a complete rehaul of the existing codebase, moving off Terraform and into using govmomi directly.

### SIG-windows

- Fixed attaching volumes after detach errors. Now volumes that failed to detach are not treated as attached. Kubernetes will make sure they are fully attached before they can be used by pods. ([#120595](https://github.com/kubernetes/kubernetes/pull/120595), [@jsafrane](https://github.com/jsafrane))

- Fully removed `PostStartHookContext.StopCh`. ([#127341](https://github.com/kubernetes/kubernetes/pull/127341), [@mjudeikis](https://github.com/mjudeikis))

  
    - When using Services with SessionAffinity, client affinity for an
      endpoint now gets broken when that endpoint becomes non-ready
      (rather than continuing until the endpoint is fully deleted).
  
    - Traffic to a service IP now starts getting rejected (as opposed to
      merely dropped) as soon as there are no longer any *usable*
      endpoints, rather than waiting until all of the terminating

- The `export` query parameter (inconsistently supported by API resources and deprecated in v1.14) is fully removed.  Requests setting this query parameter will now receive a 400 status response.
