+            Due to changed behavior in the current AWS S3 SDK, content store uploads will fail when using older MinIO versions.

+            The default ingress annotations in the `signpath-application-ingress` chart are now disabled because the Kubernetes NGINX Ingress Controller became [obsolete](https://kubernetes.io/blog/2025/11/11/ingress-nginx-retirement/).
+            * They can be manually re-enabled via `chartSettings.ingressAnnotations.nginx.enabled`.
+            * We recommend the [Traefik Kubernetes Ingress provider](https://doc.traefik.io/traefik/reference/install-configuration/providers/kubernetes/kubernetes-ingress/) as a replacement (see the "Incoming HTTP traffic" section installation guide for details).

+            The `javasigningmethodservice` deployment now requires a Linux container. If you use it, ensure that your cluster has available resources to host its replicas.
