#### Node controller
* Bug fixes:

  * Fix [transition between NotReady and Unreachable taints](https://github.com/kubernetes/kubernetes/issues/43444). ([#44042](https://github.com/kubernetes/kubernetes/pull/44042), [@gmarek](https://github.com/gmarek))


#### Node Components

* Features

- Reduced the 5s delay before tainting `node.kubernetes.io/unreachable:NoExecute` when a Node became unreachable. ([#120816](https://github.com/kubernetes/kubernetes/pull/120816), [@tnqn](https://github.com/tnqn)) [SIG Apps and Node]

- Performance of the anti-affinity predicate of the default scheduler has been improved. ([#66948](https://github.com/kubernetes/kubernetes/pull/66948), [@mohamed-mehany](https://github.com/mohamed-mehany))
- The unreachable taint gets applied to a node when it loses its network connection. ([#67734](https://github.com/kubernetes/kubernetes/pull/67734), [@Huang-Wei](https://github.com/Huang-Wei))

 * `::1` will reach the IPv6 server.
 *
 * By orchestrating two different servers with the same port but different IP addresses, we can
 * test what OkHttp does when both are reachable, or if only one is reachable.
 *
 * This test only runs on host machines that have both IPv4 and IPv6 addresses for localhost.
