- Added the `applyconfiguration` generator to the code-generator script that generates server-side apply configuration and client APIs ([#114987](https://github.com/kubernetes/kubernetes/pull/114987), [@astefanutti](https://github.com/astefanutti))

* Add generate-groups.sh and generate-internal-groups.sh to k8s.io/code-generator to easily run generators against CRD or User API Server types. ([#52186](https://github.com/kubernetes/kubernetes/pull/52186), [@sttts](https://github.com/sttts))

## Deprecations
* Remove extensions/v1beta1 Jobs resource, and job/v1beta1 generator. ([#38614](https://github.com/kubernetes/kubernetes/pull/38614), [@soltysh](https://github.com/soltysh))

- Remove deprecated `--generator, --replicas, --service-generator, --service-overrides, --schedule` from `kubectl run`

workspaces.  This should not impact end users at all, but does have impact for developers of downstream projects.  Switching to workspaces caused some breaking changes in the flags to the various k8s.io/code-generator tools.  Downstream consumers should look at staging/src/k8s.io/code-generator/kube_codegen.sh to see the changes.

#### client-go:

- Official binaries now include the golang generated build ID `buildid` instead of an empty string. ([#101411](https://github.com/kubernetes/kubernetes/pull/101411), [@saschagrunert](https://github.com/saschagrunert))
- Remove balanced attached node volumes feature. ([#102443](https://github.com/kubernetes/kubernetes/pull/102443), [@ravisantoshgudimetla](https://github.com/ravisantoshgudimetla))

- Projects which use k8s.io/code-generator and invoke `generate-groups` or `generate-internal-groups.sh` have a new, simpler script (`kube_codegen.sh`) they can use.  The old scripts are deprecated but remain intact. ([#117262](https://github.com/kubernetes/kubernetes/pull/117262), [@thockin](https://github.com/thockin))...

- The validation-gen code generator generated validation code that supported validation ratcheting. ([#132236](https://github.com/kubernetes/kubernetes/pull/132236), [@yongruilin](https://github.com/yongruilin)) [SIG API Machinery, Apps, Auth and Node]

### CLI

* Use structured generator for kubectl autoscale.  ([#55913](https://github.com/kubernetes/kubernetes/pull/55913), [@wackxu](https://github.com/wackxu))
