More things from release notes:

  • Still-served features deprecated in 1.19, found from codesearch which might miss things not in operations/puppet. These will be removed in 1.22.
    • apiextensions.k8s.io/v1beta1, used by Calico and apiregistration.k8s.io/v1beta1, used by metrics-server
    • authorization.k8s.io/v1beta1: not sure, rbac.authorization.k8s.io/v1beta1 is used heavily but not sure if rbac. is deprecated when the parent domain is
  • New stable Ingress API, ingress-admission-controller needs an update, will file a separate task
  • More visibility over deprecated feature usage, kubectl will show warnings and we have prometheus metrics
