## Changes by Kind

### Deprecation

support for a new kubectl output format, `kyaml`. KYAML was a strict subset of YAML and should be accepted by any YAML processor. The formatting of KYAML was halfway between JSON and YAML.  Because it was more explicit than the default YAML style, it was less error-prone. ([#132942](https://github.com/kubernetes/kubernetes/pull/132942), [@thockin](https://github.com/thockin)) [SIG API Machinery, Architecture, Auth, CLI, Cloud Provider, Cluster Lifecycle, Contributor Experience, Instrumentation, Network,...

* Disabled ScheduleDaemonSetPods if kubelet version less than 1.11; and ScheduleDaemonSetPods is not supported on a 1.13 control plane / 1.10 kubelet split. ([#69566](https://github.com/kubernetes/kubernetes/pull/69566), [@k82cn](https://github.com/k82cn))

- When `SchedulerQueueingHint` is enabled,
  the scheduler's in-tree plugins now subscribe to specific node events to decide whether to requeue Pods.
  This allows the scheduler to handle cluster events faster with less memory.

  Specific node events include updates to taints, tolerations or allocatable.

- Count pod overhead against an entity's ResourceQuota ([#99600](https://github.com/kubernetes/kubernetes/pull/99600), [@gjkim42](https://github.com/gjkim42)) [SIG API Machinery and Node]
- EndpointSlice controller is now less likely to emit FailedToUpdateEndpointSlices events. ([#100146](https://github.com/kubernetes/kubernetes/pull/100146), [@robscott](https://github.com/robscott)) [SIG Apps and Network]

- VSphere releases less than 7.0u2 are not supported for in-tree vSphere volume  as of Kubernetes v1.25. Please consider upgrading vSphere (both ESXi and vCenter)  to 7.0u2 or above. ([#111255](https://github.com/kubernetes/kubernetes/pull/111255), [@divyenpatel](https:/...

- Added a new command line argument `--interactive` to kubectl. The new command line argument lets a user confirm deletion requests per resource interactively. ([#114530](https://github.com/kubernetes/kubernetes/pull/114530), [@ardaguclu](https://github.com/ardaguclu)) [SIG CLI and Testing]
