- 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

- HPA controller starts to expose metrics from the kube-controller-manager.\n- `reconciliations_total`: Number of reconciliation of HPA controller. \n- `reconciliation_duration_seconds`: The time(seconds) that the HPA controller takes to reconcile once.

*   Added experimental support for an exactly-once visitation guarantee for evaluating Keras models trained with `tf.distribute ParameterServerStrategy`, via the `exact_evaluation_shards` argument in `Model.fit` and `Model.evaluate`.

- `batch/v2alpha1.ScheduledJob` is removed.

- The Job controller now creates pods in batches instead of all at once. ([#49142](https://github.com/kubernetes/kubernetes/pull/49142), [@joelsmith](https://github.com/joelsmith)).

- The `Should recreate evicted statefulset` conformance [test]( https://github.com/kubernetes/kubernetes/blob/master/test/e2e/apps/statefulset.go) fails because `Pod ss-0 expected to be re-created at least once`. This was caused by the `Predicate PodFitsHostPorts failed` scheduling error. The root cause was a host port conflict for port `21017`. This port was in-use as an ephemeral port by another application running on the node. This will be looked at for...

API server communication, the keys are case-sensitive. A bug introduced in Kubernetes 1.8 caused the API server to accept a request with incorrect case and coerce it to correct case, but this behaviour has been fixed in 1.11 and the API server will once again be enforcing the correct case. It’s worth noting that during this time, the `kubectl` tool continued to enforce case-sensitive keys, so users that strictly manage resources with `kubectl` will be unaffected by this change.
