the digits in the corresponding base.

Although these representations all result in an integer, they have
different valid ranges.  Octal escapes must represent a value between
0 and 255 inclusive.  Hexadecimal escapes satisfy this condition
by construction. The escapes <code>\u</code> and <code>\U</code>
represent Unicode code points so within them some values are illegal,

- Volume mount cleanup now considers only plugin directory and not the entire kubelet root ([#112607](https://github.com/kubernetes/kubernetes/pull/112607), [@mattcary](https://github.com/mattcary))
- `kubectl` now escapes terminal special characters in output. This fixes CVE-2021-25743.

### Other (Cleanup or Flake)

- Integration testing now takes periodic Prometheus scrapes from the etcd server.
  There is a new script ,`hack/run-prometheus-on-etcd-scrapes.sh`, that runs a containerized Prometheus server against an archive of such scrapes. ([#106190](https://github.com/kubernetes/kubernetes/pull/106190), [@MikeSpreitzer](https://github.com/MikeSpreitzer)) [SIG API Machinery and Testing]

- Add support for CEL expressions with escaped names in structured authentication config.  Using `[` for accessing claims or user data is preferred when names contain characters that would need to be escaped.  CEL optionals via `?` can be used in places where `has` cannot be used, i.e. `claims[?"kubernetes.io"]` or `user.extra[?"domain.io/foo"]`. ([#131574](https://githu...

- Modified command line errors (for example, `kubectl list` -> `unknown command`) that were printed as log message with escaped line breaks instead of a multi-line plain text, making the error hard to read. ([#107044](https://github.com/kubernetes/kubernetes/pull/107044), [@pohly](https://github.com/pohly))

    * Role bindings since the default scopes now include the "userinfo.email"
    * scope. This is a breaking change if the numeric uniqueIDs of the Google
    * service accounts were being used in RBAC role bindings. The behavior
    * can be overridden by explicitly specifying the scope values as
    * comma-separated string in the "users[*].config.scopes" field in the
    * KUBECONFIG file.

### Failing Test

- Escape the special characters like `[`, `]` and ` ` that exist in vsphere windows path ([#98830](https://github.com/kubernetes/kubernetes/pull/98830), [@liyanhui1228](https://github.com/liyanhui1228)) [SIG Storage and Windows]

### Not Very Notable (that is, non-user-facing)

- Unit tests have been added for scopes and scope selectors in the quota spec ([#66351](https://github.com/kubernetes/kubernetes/pull/66351), [@vikaschoudhary16](https://github.com/vikaschoudhary16)) Courtesy of SIG Node, and SIG Scheduling

- Ginkgo: when e2e tests are invoked through ginkgo-e2e.sh, the default now is to use color escape sequences only when connected to a terminal. `GINKGO_NO_COLOR=y/n` can be used to override that default.

* Removed always pull policy from the template for ingress on CDK. ([#61598](https://github.com/kubernetes/kubernetes/pull/61598), [@hyperbolic2346](https://github.com/hyperbolic2346))
* escape literal percent sign when formatting ([#61523](https://github.com/kubernetes/kubernetes/pull/61523), [@dixudx](https://github.com/dixudx))
