* 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))

- The cloudstack and ovirt controllers have been deprecated and will be removed in a future version. ([#68199](https://github.com/kubernetes/kubernetes/pull/68199), [@dims](https://github.com/dims))

- `kubectl run` has removed the previously deprecated generators, along with flags unrelated to creating pods. `kubectl run` now only creates pods. See specific `kubectl create` subcommands to create objects other than pods. 

### SIG Apps

* Added generators for `apps/v1` deployments. ([#61288](https://github.com/kubernetes/kubernetes/pull/61288), [@ayushpateria](https://github.com/ayushpateria))

### SIG Auth

- Fixes the message about no auth for metrics in scheduler. ([#94035](https://github.com/kubernetes/kubernetes/pull/94035), [@zhouya0](https://github.com/zhouya0)) [SIG Scheduling]
- Generators for services are removed from kubectl ([#95256](https://github.com/kubernetes/kubernetes/pull/95256), [@Git-Jiro](https://github.com/Git-Jiro)) [SIG CLI]

* Add official Microsoft project generator for [serving spaCy with FastAPI and Azure Cognitive Skills](https://github.com/microsoft/cookiecutter-spacy-fastapi) to [Project Generators](https://fastapi.tiangolo.com/project-generation/). PR [#1390](https://github.com/tiangolo/fastapi/pull/1390) by [@kabirkhan](https://github.com/kabirkhan).

OpenAPI specs for native types have long been served at /openapi/v2, and they are consumed by a number of components, notably kubectl client-side validation, kubectl explain and OpenAPI based client generators.

With Kubernetes 1.15 as beta, OpenAPI schemas are also published for CRDs, as long as their schemas are structural.

These changes are reflected in the following Kubernetes enhancements:

* 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))
