Go's implementation of RFC-3986, have duplicate "/" removed from the URL paths, and passed like that directly to the `kube-apiserver` `--etcd-servers` flag. If you have etcd endpoints that have Unicode characters, it is advisable to encode them in advance with tooling that is fully IDNA compliant. If you don't do that, the Go standard library (used in k8s and etcd) would do it for you when making requests to the endpoints.

the corresponding code point. If the iteration encounters an invalid
UTF-8 sequence, the second value will be <code>0xFFFD</code>,
the Unicode replacement character, and the next iteration will advance
a single byte in the string.

The iteration order over maps is not specified
and is not guaranteed to be the same from one iteration to the next.

* Advanced auditing is the default auditing mechanism at `v1beta1`. The new version introduces the following changes:

  * The `--audit-policy-file` option is required if the `AdvancedAuditing` feature is not explicitly turned off (`--feature-gates=AdvancedAuditing=false`) on the API server.
  * The audit log file defaults to JSON encoding when using the advanced auditing feature gate.

### **Auth**

#### **Audit**

*   RequestReceivedTimestamp and StageTimestamp are added to audit events ([#52981](https://github.com/kubernetes/kubernetes/pull/52981),[ @CaoShuFeng](https://github.com/CaoShuFeng))
*   Advanced audit policy now supports a policy wide omitStage ([#54634](https://github.com/kubernetes/kubernetes/pull/54634),[ @CaoShuFeng](https://github.com/CaoShuFeng))

#### Audit Logging
* [alpha] Advanced Auditing enhances the Kubernetes API [audit logging](https://kubernetes.io/docs/tasks/debug/debug-cluster/audit/#log-backend) capabilities through a customizable policy, pluggable audit backends, and richer audit data.

Additionally, these Kubernetes snapshot primitives act as basic building blocks that unlock the ability to develop advanced, enterprise-grade, storage administration features for Kubernetes: including application or cluster level backup solutions.
