@tjons : I made a mistake in the last release and got a prr-review for Beta, but forgot to update the code afterwards. In this release we're only updating the code and the prr-review file already exists, see: https://github.com/kubernetes/enhancements/blob/master/keps/prod-readiness/sig-network/3836.yaml

Is this fine?

[tjons]

@alexanderConstantinescu thanks for the update! This should be fine... With all the requirements fulfilled this enhancement is now marked as tracked for the upcoming enhancements freeze 🚀
