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

We have added a new feature gate ACMEHTTP01IngressPathTypeExact, to allow ingress-nginx users to turn off the new default Ingress PathType: Exact behavior, in ACME HTTP01 Ingress challenge solvers.
This change fixes the following issue: #​7791

We have increased the ACME challenge authorization timeout to two minutes, which we hope will fix a timeout error (error waiting for authorization), which has been reported by multiple users, since the release of cert-manager v1.16.0.
This change should fix the following issues: #​7337, #​7444, and #​7685.

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

cert-manager 1.18 introduces several new features and breaking changes. Highlights include support for ACME certificate profiles, a new default for Certificate.Spec.PrivateKey.RotationPolicy now set to Always (breaking change), and the default Certificate.Spec.RevisionHistoryLimit now set to 1 (potentially breaking).
