    why we're doing this and how to upgrade.

    The OkHttp 3.12.x branch will be our long-term branch for Android 2.3+ (API level 9+) and Java

- The `generate_groups.sh` and `generate_internal_groups.sh` scripts from the `k8s.io/code-generator` repo are deprecated (but still work) in favor of `kube_codegen.sh` in that same repo.  Projects which use the old scripts are encouraged to look at adopting the new one.
