  // but should apply for any default implementation. If set, it is assumed that a load balancer

### Azure

SIG Azure worked on improvements in the cloud provider, including significant work on the Azure Load Balancer implementation.

### Cluster Lifecycle

- QueueingHint implementation for NodeAffinity is reverted because we found potential scenarios where events that make Pods schedulable could be missed. ([#122327](https://github.com/kubernetes/kubernetes/pull/122327), [@sanposhiho](https://github.com/sanposhiho)) [SIG Scheduling]

- QueueingHint implementation for NodeAffinity is reverted because we found potential scenarios where events that make Pods schedulable could be missed. ([#122285](https://github.com/kubernetes/kubernetes/pull/122285), [@sanposhiho](https://github.com/sanposhiho)) [SIG Scheduling]

- Added a `.status.features.supplementalGroupsPolicy` field to Nodes. The field is true when the feature is implemented in the CRI implementation (KEP-3619). ([#125470](https://github.com/kubernetes/kubernetes/pull/125470), [@everpeace](https://github.com/everpeace)) [SIG API Machinery, Apps, Node and Testing]

### Bug or Regression

- Adds node event handlers to dual stack kube-proxy implementation to fix Topology Aware Hints. ([#101054](https://github.com/kubernetes/kubernetes/pull/101054), [@robscott](https://github.com/robscott)) [SIG Network]

* [stable] [cri-o](https://github.com/kubernetes-incubator/cri-o): CRI implementation for OCI-based runtimes [[@mrunalp](https://github.com/mrunalp)]

  * Passed all the Kubernetes 1.7 end-to-end conformance test suites.
  * Verification against Kubernetes 1.8 is planned soon after the release.

### Failing Test

- Kubelet: the HostPort implementation in dockershim was not taking into consideration the HostIP field, causing that the same HostPort can not be used with different IP addresses.

  - `service.kubernetes.io/topology-aware-hints` annotation has been deprecated.
  - kube-proxy now accepts any value that is not "disabled" for these annotations, enabling custom implementation-specific and/or future built-in heuristics to be used.
