kube-proxy is misleading, no port is opened with this address. Instead it is translated internally to "nodeIP". The nodeIPs for both families are now taken from the Node object if `--bind-address` is unspecified or set to the "any" address (0.0.0.0 or ::). It is recommended to leave `--bind-address` unspecified, and in particular avoid to set it to localhost (127.0.0.1 or ::1) ([#119525](https://github.com/kubernetes/kubernetes/pull/119525), [@uablrek](https://github.com/uablrek)) [SIG Network and Scalability]...

* client-go: PortForwarder.GetPorts() now contain correct local port if no local port was initially specified when setting up the port forwarder ([#73676](https://github.com/kubernetes/kubernetes/pull/73676), [@martin-helmich](https://github....

that evicts already-running pods, and an associated `tolerationSeconds` field to tolerations to delay the eviction for a specified amount of time. As before, taints are created using `kubectl taint` (but internally they are now represented as a field `taints` in the NodeSpec rather than using the `scheduler.alpha.kubernetes.io/taints` annotation on Node). Tolerations are now specified in a new-in-1.6 `tolerations` field of the PodSpec rather than using the `scheduler.alpha.kubernetes.io/tolerations`...

* kube-scheduler: Use default predicates/prioritizers if they are unspecified in the policy config. ([#59363](https://github.com/kubernetes/kubernetes/pull/59363), [@yguo0905](https://github.com/yguo0905))

- Fixed mounting of iSCSI volumes over IPv6 networks. ([#110688](https://github.com/kubernetes/kubernetes/pull/110688), [@jsafrane](https://github.com/jsafrane))

#### CustomResourceDefinition Defaulting

CustomResourceDefinitions also have new support for defaulting, with defaults specified using the `default` keyword in the OpenAPI validation schema. Defaults are set for unspecified fields in an object sent to the API, and when reading from etcd.

Defaulting will be available as alpha in Kubernetes 1.15 and requires structural schemas.
