 * **`CertificatePinner` now supports wildcard hostnames.** As always with
   certificate pinning, you must be very careful to avoid [bricking][brick]
   your app. You'll need to pin both the top-level domain and the `*.` domain
   for full coverage.

- Etcd image `v3.5.12` has been built. ([#123069](https://github.com/kubernetes/kubernetes/pull/123069), [@bzsuni](https://github.com/bzsuni))
- Fixed a bug in scheduler requeueing where registered wildcard cluster event sources didn't work. ([#123117](https://github.com/kubernetes/kubernetes/pull/123117), [@kerthcet](https://github.com/kerthcet))

- Add --permit-address-sharing flag to `kube-apiserver` to listen with `SO_REUSEADDR`. While allowing to listen on wildcard IPs like 0.0.0.0 and specific IPs in parallel, it avoids waiting for the kernel to release socket in `TIME_WAIT` state, and hence, considerably reducing `kube-apiserver` restart times under certain conditions. ([#93861](https://github.com/kubern...

* Add an alpha feature that makes NodeController set Taints instead of deleting Pods from not Ready Nodes. ([#41133](https://github.com/kubernetes/kubernetes/pull/41133), [@gmarek](https://github.com/gmarek))
* Make tolerations respect wildcard key ([#39914](https://github.com/kubernetes/kubernetes/pull/39914), [@kevin-wangzefeng](https://github.com/kevin-wangzefeng))

- Ingress: Add alternate backends via TypedLocalObjectReference ([#88775](https://github.com/kubernetes/kubernetes/pull/88775), [@cmluciano](https://github.com/cmluciano)) [SIG Apps and Network]
- Ingress: allow wildcard hosts in IngressRule ([#88858](https://github.com/kubernetes/kubernetes/pull/88858), [@cmluciano](https://github.com/cmluciano)) [SIG Network]

### Instrumentation

* For advanced auditing, audit policy supports subresources wildcard matching, such as "resource/", "/subresource","*". ([#55306](https://github.com/kubernetes/kubernetes/pull/55306), [@hzxuzhonghu](https://github.com/hzxuzhonghu))

- Support `FakeClientset` match subresource. ([#100939](https://github.com/kubernetes/kubernetes/pull/100939), [@wzshiming](https://github.com/wzshiming))
- The "Leader Migration" now support a wildcard component name and the default value. ([#102711](https://github.com/kubernetes/kubernetes/pull/102711), [@jiahuif](https://github.com/jiahuif))

     * Sets up the search conditions for listing duplicate host configurations.

  // Note: 90% of the time we don't add type parameters or wildcards that serve only to "tweak" the
  // desired return type. However, *nested* generics introduce a special class of problems that we
  // think tip it over into being worthwhile.

By default server certificates need to identify which hostnames they're trusted for. You may add as
many as necessary with `addSubjectAlternativeName()`. This mechanism also supports a very limited
form of wildcards `*.example.com` where the `*` must be first and doesn't match nested subdomains.

By default certificates use fast and secure 256-bit ECDSA keys. For interoperability with very old
clients use `HeldCertificate.Builder.rsa2048()`.
