 **ACTION REQUIRED:** In order to merge code into a release, there must be an issue in [kubernetes/enhancements] referencing this KEP and targeting a release milestone **before [Enhancement Freeze](https://github.com/kubernetes/sig-release/tree/master/releases)
 of the targeted release**.
 
-For enhancements that make changes to code or processes/procedures in core Kubernetes i.e., [kubernetes/kubernetes], we require the following Release Signoff checklist to be completed.

-Check these off as they are completed for the Release Team to track. These checklist items _must_ be updated for the enhancement to be released.

-**Note:** Any PRs to move a KEP to `implementable` or significant changes once it is marked `implementable` should be approved by each of the KEP approvers. If any of those approvers is no longer appropriate than changes to that list should be approved by the remaining approvers and/or the owning SIG (or SIG-arch for cross cutting KEPs).

-**Note:** This checklist is iterative and should be reviewed and updated every time this enhancement is being considered for a milestone.
