  - The deprecated versionless API group accessors (like `clientset.Apps()`) have been removed. Use an explicit version instead (like `clientset.AppsV1()`) ([#74422](https://github.com/kubernetes/kubernetes/pull/74422), [@liggitt](https://github.com/liggitt))

            Specifies an explicit target path, overriding the default value.
            The path is relative to the {@code ${project.build.outputDirectory}} directory,
            which is typically {@code target/classes} in a Java project.

- Added new -f flag into debug command to be used passing pod or node files instead explicit names. ([#111453](https://github.com/kubernetes/kubernetes/pull/111453), [@ardaguclu](https://github.com/ardaguclu))

## Urgent Upgrade Notes

### (No, really, you MUST read this before you upgrade)

#### kube-apiserver:
- in an `--encryption-provider-config` config file, an explicit `cacheSize: 0` parameter previously silently defaulted to caching 1000 keys. In Kubernetes 1.18, this now returns a config validation error. To disable caching, you can specify a negative cacheSize value in Kubernetes 1.18+.

e-after\narticle, aside, figcaption, figure, footer, header, hgroup, main, nav, section {\n  display: block;\n}\n\n// Body\n//\n// 1. Remove the margin in all browsers.\n// 2. As a best practice, apply a default `background-color`.\n// 3.

- The command line flag `enable-taint-manager` for kube-controller-manager is deprecated and will be removed in 1.26. The feature that it supports, taint based eviction, is enabled by default and will continue to be implicitly enabled when the flag is removed. ([#111411](https://github.com/kubernetes/kubernetes/pull/111411), [@alculquicondor](https://github.com/alculquicondor))

* Restored old behavior to the `--template` flag in `get.go`. In old releases, providing a `--template` flag value and no `--output` value implicitly assigned a default value ("go-template") to `--output`, printing using the provided template argument.
([#65377](https://github.com/kubernetes/kubernetes/pull/65377),[@juanvallejo](https://github.com/juanvallejo))

* bump(golang.org/x/oauth2): a6bd8cefa1811bd24b86f8902872e4e8225f74c4 ([#45056](https://github.com/kubernetes/kubernetes/pull/45056), [@ericchiang](https://github.com/ericchiang))
* apimachinery: make explicit that meta.KindToResource is only a guess ([#45272](https://github.com/kubernetes/kubernetes/pull/45272), [@sttts](https://github.com/sttts))

* Fix incorrect retry logic in scheduler ([#50106](https://github.com/kubernetes/kubernetes/pull/50106), [@julia-stripe](https://github.com/julia-stripe))
* Enforce explicit references to API group client interfaces in clientsets to avoid ambiguity. ([#49370](https://github.com/kubernetes/kubernetes/pull/49370), [@sttts](https://github.com/sttts))

*   deviceplugin has been extended to more gracefully handle the full device plugin lifecycle, including: ([#55088](https://github.com/kubernetes/kubernetes/pull/55088),[ @jiayingz](https://github.com/jiayingz))
    *   Kubelet now uses an explicit cm.GetDevicePluginResourceCapacity() function that makes it possible to more accurately determine what resources are inactive and return a more accurate view of available resources.
