Kubeflow AI reference platform v1.11.0-rc.1

This pre-release supports Kubernetes 1.33+ and transparently switches from Minio to seaweedfs as S3 storage. Please backup and restore any data that you have on MinIO if needed. Please try it out and provide development feedback.

Highlights:

• Massive scalability improvements that should allow you to scale to 1000+ users/profies/namespaces
• By default namespaces/profiles have zero pod overhead now, so you save 2x number of namespaces pods.
• By default the Istio service mesh is pruned to save Terabytes of Istio sidecar memory and network traffic on very large clusters #3206
• S3 storage with hard multi-tenancy and per namespace credentials. Limitations of kubeflow/pipelines#12373 and kubeflow/pipelines#9889 still apply. See also https://blog.kubeflow.org/gsoc/community/kubeflow/2025/09/06/kubeflow-and-gsoc2025.html#project-1-kubeflow-platform-enhancements for more information.
• PodSecurityStandards restricted is enforced for all system namespaces. PodSecurityStandards baseline is enforced for user namespaces https://kubernetes.io/docs/concepts/security/pod-security-standards/
• Automatic tests/documentation for exposing Kserve inference services with authentication inside and outside of the cluster https://github.com/kubeflow/manifests/blob/v1.11-branch/.github/workflows/katib_test.yaml
• Experimental helm charts development has started https://github.com/kubeflow/manifests/tree/v1.11-branch/experimental/helm/charts
• Typical resource consumption per component https://github.com/kubeflow/manifests/tree/v1.11-branch#kubeflow-version-master
• KFP 2.15.0 (still supports V1 pipelines and the 1.8.23 SDK), Trainer 2.1.0, Training Operator 1.9.2, Katib 0.19.0, KServe 0.15.2, Kserve models web application 0.15.0, Spark operator 2.4.0, Istio 1.28.0, DEX 2.44, OAuth2-Proxy 7.13
• Network Policies for the namespaces knative-serving oauth2-proxy cert-manager istio-system auth by @kunal-511 in #3228
• Massive test improvements across repositories which should lead to significantly higher quality releases.
• So far this release was tested on Kind and GKE (with GKE specific istio overlay), but should also work on AKS, EKS, Rancher and many other Kubernetes clusters.
