📋 Recommended Actions ✅ No Immediate Action Required No immediate action required. Review updates to better support your users, especially around ACME HTTP01 challenge handling and Ingress-Nginx compatibility. 📝 Summary cert-manager v1.18.1 delivers critical enhancements for ACME HTTP01 challenges and improved compatibility with Ingress-Nginx. This release introduces the ACMEHTTP01IngressPathTypeExact feature gate, now Beta and enabled by default, which switches the Ingress pathType to Exact for heightened security. This prevents misinterpretations of challenge paths and aligns with standard Ingress behaviors. A significant dependency upgrade bumps Ingress-Nginx to v1.12.3, coupled with a vital configuration change that disables strict-validate-path-type to prevent HTTP01 challenge failures caused by a bug in newer Ingress-Nginx versions. Furthermore, the ACME authorization timeout is extended from 20 seconds to 2 minutes, significantly improving reliability for challenges against slower ACME servers or under poor network conditions. The DefaultPrivateKeyRotationPolicyAlways feature gate is also promoted to Beta, ensuring consistent private key rotation. Review these changes to ensure optimal ACME challenge resolution and cluster stability. ...
