Bug or Regression

• Helm: Fix invalid YAML generated when both webhook.config and webhook.volumes are defined. (#8665, @​cert-manager-bot)

• Bump go dependencies with reported vulnerabilities (#8704, @​erikgb)
• Bump go to 1.26.2 (#8703, @​erikgb)

v1.20.1

cert-manager is the easiest way to automatically manage certificates in Kubernetes and OpenShift clusters.

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)

v1.20.0

cert-manager is the easiest way to automatically manage certificates in Kubernetes and OpenShift clusters.

v1.20.0 adds alpha support for the new ListenerSet resource, adds support for Azure Private DNS; parentRefs are no longer required when using ACME with Gateway API, and OtherNames was promoted to Beta.

Changes by Kind

Feature

• Added a set of flags to permit setting NetworkPolicy across all deployed containers. Remove redundant global IP ranges from example policies. (#8370, @​jcpunk)
• Added selectable fields to custom resource definitions for .spec.issuerRef.{group, kind, name} (#8256, @​tareksha)
• Added support for specifying imagePullSecrets in the startupapicheck-job Helm template to enable pulling images from private registries. (#8186, @​mathieu-clnk)
• Added 'extraContainers' helm chart value, allowing the deployment of arbitrary sidecar containers within the cert-manager operator pod. This can be used to support, for e.g., AWS IAM Roles Anywhere for Route53 DNS01 verification. (#8355, @​dancmeyers)
• Added parentRef override annotations on the Certificate resource. (#8518, @​hjoshi123)
• Added support for azure private zones for dns01 issuer. (#8494, @​hjoshi123)
• Added support for configuring PEM decoding size limits, allowing operators to handle larger certificates and keys. (#7642, @​robertlestak)
• Added support for unhealthyPodEvictionPolicy in PodDisruptionBudget (#7728, @​jcpunk)
• For Venafi provider, read venafi.cert-manager.io/custom-fields annotation on Issuer/ClusterIssuer and use it as base with override/append capabilities on Certificate level. (#8301, @​k0da)
• Improve error message when CA issuers are misconfigured to use a clashing secret name (#8374, @​majiayu000)
• Introduce a new Ingress annotation acme.cert-manager.io/http01-ingress-ingressclassname to override http01.ingress.ingressClassName field in HTTP-01 challenge solvers. (#8244, @​lunarwhite)
• Update global.nodeSelector to helm chart to perform a merge and allow for a single nodeSelector to be set across all services. (#8195, @​StingRayZA)
