- `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.

### Bug or Regression

- Fixed a regression since 1.27.0 in scheduler framework when running score plugins. 
  The `skippedScorePlugins` number might be greater than `enabledScorePlugins`, 
  so when initializing a slice the cap(len(skippedScorePlugins) - len(enabledScorePlugins)) is negative, 

cores, or unique hardware devices) could trigger the failure. While this behavior is correct it reduces the throughput of pod execution and creates user-visible warnings - [future versions of Kubernetes will minimize the likelihood users see pod failures due to this issue](https://github.com/kubernetes/kubernetes/issues/106884). In general, any automation that creates pods [must take Kubelet rejections into account](https://kubernetes.io/docs/concepts/scheduling-eviction/#pod-disruption), and should be...

- `batch/v2alpha1.ScheduledJob` is removed.

- 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)).

# v1.9.9

- Fixed the following 
  -  AWS Cloud Provider attempts to delete LoadBalancer security group it didn’t provision

- Added support for projected volume in describe function  ([#70158](https://github.com/kubernetes/kubernetes/pull/70158), [@WanLinghao](https://github.com/WanLinghao))
- kubeadm now automatically creates a new stacked etcd member when joining a new control plane node (does not applies to external etcd) ([#69486](https://github.com/kubernetes/kubernetes/pull/69486), [@fabriziopandini](https://github.com/fabriziopandini))
