<h3 id="String_types">String types</h3>

<p>
A <i>string type</i> represents the set of string values.
A string value is a (possibly empty) sequence of bytes.
The number of bytes is called the length of the string and is never negative.
Strings are immutable: once created,
it is impossible to change the contents of a string.
The predeclared string type is <code>string</code>;
it is a <a href="#Types">named type</a>.

- Empty values are no longer assigned to undefined resources (CPU or memory) when storing the resources allocated to the pod in checkpoint. ([#117615](https://github.com/kubernetes/kubernetes/pull/117615), [@aheng-ch](https://github.com/aheng-ch))
- Fixed CEL estimated cost of `replace()` to handle a zero length replacement string correctly.

* Fix a bug where kubelet would not retry pod sandbox creation when the restart policy of the pod is Never ([#79451](https://github.com/kubernetes/kubernetes/pull/79451), [@yujuhong](https://github.com/yujuhong))

- K8s.io/apimachinery: Introduced a helper function to compare `resourceVersion` strings between two objects of the same resource. ([#134330](https://github.com/kubernetes/kubernetes/pull/134330), [@michaelasp](https://github.com/michaelasp)) [SIG API Machinery, Apps, Auth, Instrumentation, Network, Node, Scheduling, Storage and Testing]...

- DRA: CEL expressions using attribute strings exceeded the cost limit because their cost estimation was incomplete. ([#129661](https://github.com/kubernetes/kubernetes/pull/129661), [@pohly](https://github.com/pohly)) [SIG Node]

- Graduated relaxed DNS search string validation to GA. For the Pod API, `.spec.dnsConfig.searches`
  now allows an underscore (`_`) where a dash (`-`) would be allowed, and it allows search strings be a single dot `.`. ([#132036](https://github.com/kubernetes/kubernetes/pull/132036), [@adrianmoisey](https://github.com/adrianmoisey)) [SIG Network and Testing]

## Changelog since v1.32.2

## Changes by Kind

### API Change

  
  The API does include a few breaking changes:
  - The "extraArgs" component construct is now a list of "name"/"value" pairs instead of a string/string map. This has been done to support duplicate args where needed.
  - The "JoinConfiguration.discovery.timeout" field has been replaced by "JoinConfiguration.timeouts.discovery".

- The `kubectl create service` now respects the `namespace` flag. ([#101005](https://github.com/kubernetes/kubernetes/pull/101005), [@zxh326](https://github.com/zxh326))
- The `kubectl get` now truncates multi-line strings to avoid breaking printing ([#103514](https://github.com/kubernetes/kubernetes/pull/103514), [@soltysh](https://github.com/soltysh))

    * rbac.authorization.k8s.io/v1alpha1

    * settings.k8s.io/v1alpha1

    * If you wish to continue using them in v1.8, please enable them explicitly using the `--runtime-config` flag on the apiserver (for example, `--runtime-config="rbac.authorization.k8s.io/v1alpha1,settings.k8s.io/v1alpha1"`)
