- Generated OpenAPI model packages for API types into `zz_generated.model_name.go` files, accessible via the `OpenAPIModelName()` function. This allows API authors to declare desired OpenAPI model packages instead of relying on the Go package path of API types. ([#131755](https://github.com/kubernetes/kubernetes/pull/131755), [@jpbetz](https://github.com/jpbetz))...

  * 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

- Removed all support for _classic_ dynamic resource allocation (DRA). The `DRAControlPlaneController` feature gate, formerly alpha, is no longer available. Kubernetes now only uses the _structured parameters_ model (also alpha) for allocating dynamic resources to Pods.

* Fix VMSS LoadBalancer backend pools so that the network won't be broken when instances are upgraded to latest model ([#81411](https://github.com/kubernetes/kubernetes/pull/81411), [@nilo19](https://github.com/nilo19))

### SIG Instrumentation

As far as Sig Instrumentation, the major change in Kubernetes 1.11 is the deprecation of Heapster as part of ongoing efforts to move to the new Kubernetes monitoring model. Clusters still using Heapster for autoscaling should be migrated over to metrics-server and the custom metrics API. See the deprecation section for more information.
