Bug fixes:

• Fix non-conforming GPT partition table (flatcar/Flatcar#1651)
• Fix update-ca-certificates behavior when concatenating certificates with missing trailing newlines. (flatcar/scripts#2667)
• Fixed PXE boot failures that arose since upgrading to systemd v256. Users were dumped to an emergency shell. (flatcar/bootengine#103)
• The kernel module build directory now contains native binaries in arm64 images instead of the previous amd64 binaries (scripts#2694)
• Nvidia driver installer service now supports the 570 driver branch by forcing the use of the proprietary kernel module. The 570 branch defaults to the kernel-open driver which requires loading firmware, which is not yet supported on Flatcar. (scripts#2694)
• azure: Fixed issue of wa-linux-agent overriding ssh public key from ignition configuration during provisioning (flatcar/Flatcar#1661)

Changes:

• Add changes for our secureboot signed images with our signed release process until the official shim signing (scripts#2754)
• Added support for ARM64 architecture in the NVIDIA driver installer service (scripts#2694)
• Added new image signing pub key to flatcar-install, needed for download verification of releases built from March 2025 onwards, if you have copies of flatcar-install or the image signing pub key, you need to update them as well (init#129)
• Build Intel iGPU i915 driver as module (scripts#2349)
• Enabled EROFS module with XATTR support (Flatcar#1659)
