- If the feature-gate VolumeAttributesClass is enabled, when finding a suitable persistent volume for a claim, the kube-controller-manager will be aware of the `volumeAttributesClassName` field of PVC and PV objects. The `volumeAttributesClassName` field is a reference to a VolumeAttributesClass object, which contains...

* Fixes bug finding master replicas in GCE when running multiple Kubernetes clusters. ([#58561](https://github.com/kubernetes/kubernetes/pull/58561), [@jesseshieh](https://github.com/jesseshieh))

  // Init containers may not have Lifecycle actions, Readiness probes, Liveness probes, or Startup probes.
  // The resourceRequirements of an init container are taken into account during scheduling
  // by finding the highest request/limit for each resource type, and then using the max of
  // of that value or the sum of the normal containers. Limits are applied to init containers
  // in a similar fashion.

  - Clone `kubernetes/kubernetes` in `update-vendor.sh` shallowly, instead of fetching all revisions
  - Speed up binpacking by reducing the number of PreFilter calls (call once per pod instead of #pods*#nodes times)
  - Speed up finding unneeded nodes by 5x+ in very large clusters by reducing the number of PreFilter calls
  - Expose `--max-nodes-total` as a metric
  - Errors in `IncreaseSize` changed from type `apiError` to `cloudProviderError`
