- **Network**
  - [stable] Services can reference another service by DNS name, rather than being hosted in pods ([kubernetes/features#33](https://github.com/kubernetes/enhancements/issues/33))

* Features:

  * Add Host field to TCPSocketAction ([#42902](https://github.com/kubernetes/kubernetes/pull/42902), [@louyihua](https://github.com/louyihua))

	* Add the ability to lock on ConfigMaps to support HA for self hosted components ([#42666](https://github.com/kubernetes/kubernetes/pull/42666), [@timothysc](https://github.com/timothysc))

- If the user specifies an invalid timeout in the request URL, the request will be aborted with an HTTP 400.

   * Evaluates whether the argument is a 6to4 address.
   *
   * <p>6to4 addresses begin with the {@code "2002::/16"} prefix. The next 32 bits are the IPv4
   * address of the host to which IPv6-in-IPv4 tunneled packets should be routed.
   *
   * <p>For more on 6to4 addresses see section 2 of <a target="_parent"
   * href="http://tools.ietf.org/html/rfc3056#section-2">RFC 3056</a>.
   *

 * [Set]. Doing so is both inefficient because equality may require a DNS lookup, and incorrect
 * because unequal URLs may be equal because of how they are hosted.
 *
 * ### Equal URLs should be equal
 *
 * These two URLs are semantically identical, but `java.net.URI` disagrees:
 *
 *  * http://host:80/
 *
 *  * http://host
 *

### Cluster Lifecycle

#### kubeadm

* [beta] A new `upgrade` subcommand allows you to automatically upgrade a self-hosted cluster created with kubeadm. ([#296](https://github.com/kubernetes/enhancements/issues/296), [@luxas](https://github.com/luxas))
