Longhornv1.12.1Storage & DataAug 14, 2026

CHECK 6PLAN 1OTHER 46View full analysis

A release with breaking behavior for legacy V2 linked-clone volumes, a Kubernetes v1.25 minimum, and stronger default network controls, including expanded mTLS enforcement. It also adds V2 data engine capabilities and metrics while correcting defects across V2 operations, backups, expansion, and infrastructure.

Check if affected (6)

breakingInternal NetworkPolicy resources enabled by default
Applies if a NetworkPolicy provider is available in the cluster.
Longhorn v1.12.1 enables ingress NetworkPolicy resources by default for internal component endpoints and RPCs, including the instance-manager gRPC endpoint. The policies take effect only when a NetworkPolicy provider is available, and the minimum required Kubernetes version is v1.25.
breakingCross-namespace Prometheus scraper access through the Longhorn Manager network policy
Applies if you use cross-namespace Prometheus scrapers.
ServiceMonitor discovery does not automatically authorize network traffic. Cross-namespace Prometheus scrapers might be blocked by the Longhorn Manager's network policy and require a scoped additive policy.
breakingmTLS for all instance-manager gRPC services
Applies if you configure the longhorn-grpc-tls secret.
When the longhorn-grpc-tls secret is configured, Longhorn v1.12.1 extends mTLS to all remaining instance-manager gRPC services, including the disk and SPDK services. Every instance-manager gRPC port then requires a valid client certificate.
