v1.18.3

Compare Source

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

We fixed a bug which caused certificates to be re-issued unexpectedly, if the issuerRef kind or group was changed to one of the "runtime" default values. We increased the size limit when parsing PEM certificate chains to handle leaf certificates with large numbers of DNS named or other identities. We upgraded Go to 1.24.9 to fix various non-critical security vulnerabilities.
