- The `kubectl top` command now includes a `--sort-by` option to sort by `memory` or `cpu`. ([#75920](https://github.com/kubernetes/kubernetes/pull/75920), [@artmello](https://github.com/artmello))

 
## Changes by Kind

### Deprecation

- Changed `kubectl version` default output to be identical to what `kubectl version --short` printed,
  and removed `--short` flag entirely. ([#116720](https://github.com/kubernetes/kubernetes/pull/116720), [@soltysh](https://github.com/soltysh))

* Fixed --save-config in create subcommand to save the annotation ([#40289](https://github.com/kubernetes/kubernetes/pull/40289), [@xilabao](https://github.com/xilabao))
* Fixed an issue where 'kubectl get --sort-by=' would return an error if the specified fields in sort were not specified in one or more of the returned objects. ([#40541](https://github.com/kubernetes/kubernetes/pull/40541), [@fabianofranz](https://github.com/fabianofranz))

- `data_key_generation_latencies_microseconds` -> `data_key_generation_latencies_seconds`

## Notable Features

- Increased the histogram resolution of the API server client certificate  to accommodate short-lived (< 6h) client certificates. ([#74806](https://github.com/kubernetes/kubernetes/pull/74806), [@mxinden](https://github.com/mxinden))

* Stability: Make Pod delete event handling of scheduler more robust. ([#58712](https://github.com/kubernetes/kubernetes/pull/58712), [@bsalamat](https://github.com/bsalamat))* Allow scheduler set AlwaysCheckAllPredicates, short circuit all predicates if one predicate fails can greatly improve the scheduling performance. ([#56926](https://github.com/kubernetes/kubernetes/pull/56926), [@wgliang](https://github.com/wgliang))

### Other (Cleanup or Flake)

### Introducing Graceful Node Shutdown (Alpha)

- The Job controller now creates pods in batches instead of all at once. ([#49142](https://github.com/kubernetes/kubernetes/pull/49142), [@joelsmith](https://github.com/joelsmith)).

- Short `.spec.ActiveDeadlineSeconds` is properly applied to a Job. ([#48545](https://github.com/kubernetes/kubernetes/pull/48454), [@weiwei4](https://github.com/weiwei04)).
