- A new flag, `--keepalive`, has been introduced, for kubectl proxy to allow setting keep-alive period for long-running request. ([#63793](https://github.com/kubernetes/kubernetes/pull/63793), [@hzxuzhonghu](https://github.com/hzxuzhonghu))

- Fixed a regression since 1.27.0 in scheduler framework when running score plugins. 
  The `skippedScorePlugins` number might be greater than `enabledScorePlugins`, 
  so when initializing a slice the cap(len(skippedScorePlugins) - len(enabledScorePlugins)) is negative, 
  which is not allowed. ([#121667](https://github.com/kubernetes/kubernetes/pull/121667), [@kerthcet](https://github.com/kerthcet)) [SIG Scheduling]

* enable recursive processing in kubectl rollout ([#25110](https://github.com/kubernetes/kubernetes/pull/25110), [@metral](https://github.com/metral))
* Support struct,array,slice types when sorting kubectl output ([#25022](https://github.com/kubernetes/kubernetes/pull/25022), [@zhouhaibing089](https://github.com/zhouhaibing089))

- Fixed an error processing watch events when running skewed apiservers ([#73482](https://github.com/kubernetes/kubernetes/pull/73482), [@liggitt](https://github.com/liggitt))
- jsonpath expressions containing `[start:end:step]` slice are now evaluated correctly ([#73149](https://github.com/kubernetes/kubernetes/pull/73149), [@liggitt](https://github.com/liggitt))

- Fixed a regression since `v1.27.0` in the scheduler framework when running score plugins. 
  The `skippedScorePlugins` number might be greater than `enabledScorePlugins`, 
  so when initializing a slice the `cap(len(skippedScorePlugins) - len(enabledScorePlugins))` is negative, 
  which is not allowed. ([#121632](https://github.com/kubernetes/kubernetes/pull/121632), [@kerthcet](https://github.com/kerthcet))

### Other (Cleanup or Flake)

- Kube-apiserver: sets an upper-bound on the lifetime of idle keep-alive connections and time to read the headers of incoming requests ([#103958](https://github.com/kubernetes/kubernetes/pull/103958), [@liggitt](https://github.com/liggitt)) [SIG API Machinery and Node]

## Dependencies

    * --alpha-endpoint-reconciler-type=(master-count, lease, none) (default
    * "master-count"). The original reconciler is 'master-count'. The 'lease'
    * reconciler uses the storageapi and a TTL to keep alive an endpoint within the
    * `kube-apiserver-endpoint` storage namespace. The 'none' reconciler is a noop
    * reconciler that does not do anything. This is useful for self-hosted
    * environments.

### Bug or Regression

- Fixed a regression since 1.27.0 in scheduler framework when running score plugins. 
  The `skippedScorePlugins` number might be greater than `enabledScorePlugins`, 
  so when initializing a slice the cap(len(skippedScorePlugins) - len(enabledScorePlugins)) is negative,

 * kubeadm: The Token-related fields in the `MasterConfiguration` object have now been refactored. Instead of the top-level `.Token`, `.TokenTTL`, `.TokenUsages`, `.TokenGroups` fields, there is now a `BootstrapTokens` slice of `BootstrapToken` objects that support the same features under the `.Token`, `.TTL`, `.Usages`, `.Groups` fields. ([#64408](https://github.com/kubernetes/kubernetes/pull/64408), [@luxas](https://github.com/luxas))

- `kubectl get -w` now takes an `--output-watch-events` flag to indicate the event type (ADDED, MODIFIED, DELETED) ([#72416](https://github.com/kubernetes/kubernetes/pull/72416), [@liggitt](https://github.com/liggitt))
- Adds Endpoint Slice support for kubectl when discovery API group is enabled. ([#81795](https://github.com/kubernetes/kubernetes/pull/81795), [@robscott](https://github.com/robscott))
