v1.15.0

Major Features

This release brings support for Secure Boot on platforms using UEFI boot; the Linux 6.1 kernel; systemd-networkd and systemd-resolved for host networking; and XFS as the filesystem for local storage.

These features are enabled by default in the new variants. Existing variants will continue to use earlier kernels, wicked for host networking, and EXT4 as the filesystem for local storage.

Known Incompatibilities

• Variants using the 6.1 kernel (aws-ecs-2/aws-ecs-2-nvidia, aws-k8s-1.28/aws-k8s-1.28-nvidia, vmware-k8s-1.28, and metal-k8s-1.28) do not support LustreFS (#3459)

Deprecation Notice

The functionality to apply a hotpatch for log4j CVE-2021-44228 has been removed. The corresponding setting, settings.oci-hooks.log4j-hotpatch-enabled, is still available for backwards compatibility. However, it has no effect beyond printing a deprecation warning to the system logs. (#3401)
