* 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))

- 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))

### 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))

- 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...

  // +optional
  optional string key = 1;

  // Operator represents a key's relationship to the value.
  // Valid operators are Exists and Equal. Defaults to Equal.
  // Exists is equivalent to wildcard for value, so that a pod can
  // tolerate all taints of a particular category.
  // +optional
  optional string operator = 2;

  // Value is the taint value the toleration matches to.

- 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))

- 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]

- When creating a networking.k8s.io/v1 Ingress API object, `spec.rules[*].http` values are now validated consistently when the `host` field contains a wildcard. ([#93954](https://github.com/kubernetes/kubernetes/pull/93954), [@Miciah](https://github.com/Miciah)) [SIG CLI, Cloud Provider, Cluster Lifecycle, Instrumentation, Network, Storage and Testing]

### Other (Cleanup or Flake)

   verbosity at runtime for JSON output. ([#114609](https://github.com/kubernetes/kubernetes/pull/114609), [@pohly](https://github.com/pohly))
- Encryption of API Server at rest configuration now allows the use of wildcards in the list of resources.  For example, *.* can be used to encrypt all resources, including all current and future custom resources. ([#115149](https://github.com/kubernetes/kubernetes/pull/115149), [@nilekhc](https://github.com/nilekhc))

* Fixes segmentation fault issue with Protobuf library when log entries are deeply nested. ([#77224](https://github.com/kubernetes/kubernetes/pull/77224), [@qingling128](https://github.com/qingling128))
* kubeadm: support sub-domain wildcards in certificate SANs ([#76920](https://github.com/kubernetes/kubernetes/pull/76920), [@sempr](https://github.com/sempr))
