- 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))...

* kubeadm 1.8 now properly handles upgrades from to 1.7.x to newer release in 1.7 branch ([#53338](https://github.com/kubernetes/kubernetes/pull/53338), [@kad](https://github.com/kad))
* 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))

- 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))

- Omit enum declarations from the static openapi file captured at https://git.k8s.io/kubernetes/api/openapi-spec. This file is used to generate API clients, and use of enums in those generated clients (rather than strings) can break forward compatibility with additional future values in those fields.
