- Kubernetes no longer monitors firewalld. On systems using firewalld for firewall
  maintenance, kube-proxy will take slightly longer to recover from disruptive
  firewalld operations that delete kube-proxy's iptables rules.

  As a side effect of these changes, kube-proxy's

- **Cluster Ops**
  - [alpha] Added ability to create/remove clusters w/highly available (replicated) masters on GCE using kube-up/kube-down scripts. ([docs](http://kubernetes.io/docs/admin/ha-master-gce/)) ([kubernetes/features#48](https://github.com/kubernetes/enhancements/issues/48))

## Dependencies

* Performance test framework and basic tests for the IPAM controller, to simulate behavior of the four supported modes under lightly loaded and loaded conditions, where load is defined as the number of operations to perform as against the configured kubernetes.

are the jurors.'  She said this last word two or three times over
to herself, being rather proud of it:  for she thought, and
rightly too, that very few little girls of her age knew the
meaning of it at all.  However, `jury-men' would have done just
as well.

  The twelve jurors were all writing very busily on slates.

- When the `StrictIPCIDRValidation` feature gate is enabled, Kubernetes will be
  slightly stricter about what values will be accepted as IP addresses and network
  address ranges (“CIDR blocks”).
  
  In particular, octets within IPv4 addresses are not allowed to have any leading
