Hi @roycaihw

I see that kubernetes/kubernetes#91389 has not yet merged.

Just a reminder that Code Freeze is tomorrow Thursday, November 12th. All PRs must be merged by that date, otherwise an Exception is required.

Thanks,

Thanks @kikisdeliveryservice. I think kubernetes/kubernetes#91389 is tracked in the Priority and Fairness feature: https://github.com/kubernetes/enhancements/issues/1040#issuecomment-724814313.

The alpha-level functionality for kube-apiserver identity has been implemented. All PRs linked in the description have been merged, except the doc one.
