v1.20.1

Compare Source

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)
