CoreDNS is now the default cluster DNS passing all of the scale/resource usage tests
Node-local DNS cache feature is available in Alpha. This feature deploys a lightweight DNS caching Daemonset that avoids the conntrack and converts queries from UDP to more reliable TCP.
PodReady++ feature now has `kubectl` CLI support.

Progress was made towards finalizing the IPv6 dual stack support KEP and support for topological routing of services.

* Skip errors when unregistering juju kubernetes-workers ([#48144](https://github.com/kubernetes/kubernetes/pull/48144), [@ktsakalozos](https://github.com/ktsakalozos))
* Configures the Juju Charm code to run kube-proxy with conntrack-max-per-core set to 0 when in an lxc as a workaround for issues when mounting /sys/module/nf_conntrack/parameters/hashsize ([#48450](https://github.com/kubernetes/kubernetes/pull/48450), [@wwwtyro](https://github.com/wwwtyro))

- Fixes a regression introduced in 1.29 where conntrack entries for UDP connections
  to deleted pods did not get cleaned up correctly, which could (among other things)

   * documentation.

  public void add(Runnable runnable, Executor executor) {
    // Fail fast on a null. We throw NPE here because the contract of Executor states that it throws
    // NPE on null listener, so we propagate that contract up into the add method as well.
    checkNotNull(runnable, "Runnable was null.");
    checkNotNull(executor, "Executor was null.");

  * When annotating existing internal code, use `org.jetbrains.annotations.Contract`, e.g. `@Contract(null -> null; !null -> !null)`.
      When doing so, still annotate nullable parameters and the return type as `@Nullable`.
  * Do not use `@Contract` for public APIs.
  * For polynull public APIs, the solution has to be decided on a case-by-case basis.
