v1.20.1 fixes an issue for OpenShift users that has to do with the finalizer RBAC, bumps gRPC to address a reported non-affecting vulnerability, and fixes a duplicate parentRef bug when both issuer config and annotations are present (Gateway API).

Bug or Regression

  • Fixed duplicate parentRef bug when both issuer config and annotations are present. (#8658, @hjoshi123)
  • Add missing issuer finalizer RBAC to the order controller to support owner references. This was preventing OpenShift users from being able to upgrade to v1.20.0. (#8655, @erikgb)
  • Bump google.golang.org/grpc to fix vulnerability reported by scanners. This isn't a vulnerability that affects cert-manager, but we are bumping it because it is reported by scanners. (#8657, @erikgb)
