* kubectl: don't display an empty list when trying to get a single resource that isn't found ([#28294](https://github.com/kubernetes/kubernetes/pull/28294), [@ncdc](https://github.com/ncdc))

 *  New: Switch our Internationalized Domain Name (IDN) implementation to [UTS #46 Nontransitional
    Processing][uts46]. With this fix, the `ß` code point no longer maps to `ss`. OkHttp now embeds
    its own IDN mapping table in the library.

- Fix bug where Server Side Apply causes spurious resourceVersion bumps on no-op patches to custom resources. ([#125263](https://github.com/kubernetes/kubernetes/pull/125263), [@jpbetz](https://github.com/jpbetz)) [SIG API Machinery and Testing]

### Instrumentation
- Bump version of event-exporter to 0.3.1, to switch it to protobuf. ([#83396](https://github.com/kubernetes/kubernetes/pull/83396), [@loburm](https://github.com/loburm))
- Bumps metrics-server version to v0.3.6 with following bugfix:

    return hextetsToIPv6String(hextets) + scopeWithDelimiter((Inet6Address) ip);
  }

  private static String scopeWithDelimiter(Inet6Address ip) {
    // getHostAddress on android sometimes maps the scope ID to an invalid interface name; if the
    // mapped interface isn't present, fallback to use the scope ID (which has no validation against
    // present interfaces)

    removed obsolete code for Android 4.4 we inadvertently also removed support for custom
    subclasses. We've restored that support!

 *  **This release bumps our minimum requirements to Java 8+ or Android 5+.** Cutting off old
    devices is a serious change and we don't do it lightly! [This post][require_android_5] explains
    why we're doing this and how to upgrade.

- Fixed a bug where CEL expressions in CRD validation rules would incorrectly compute a high estimated cost for functions that return strings, lists or maps.
