Talos 1.13.0-alpha.0 (2025-12-25)

Welcome to the v1.13.0-alpha.0 release of Talos!
This is a pre-release of Talos

Please try out the release binaries and report any issues at
https://github.com/siderolabs/talos/issues.

External Volumes

Talos now supports virtiofs-based external volumes via the new
ExternalVolumeConfig
document.

These virtiofs external volumes are not supported when SELinux is running
in enforcing mode.

Talos Imager Enhancements

Talos imager now supports running rootless. --privileged and -v /dev:/dev are no longer required.

Container Image Decompression

Talos now ships with igzip (amd64) and pigz (arm64) to speed up container image decompression.

/proc/PID/mem Access Hardening

A new kernel parameter proc_mem.force_override=never has been introduced by default to enhance system security
by preventing unwanted writes to protected process memory via /proc/PID/mem.
If the kernel parameter is removed, default behavior is restored, allowing access only if the process is traced.

Reproducible Disk Images

Talos disk images are now reproducible. Building the same version of Talos multiple times will yield
identical disk images.

Note: VHD and VMDK (Azure and VMware) images are not currently reproducible due to limitations in the underlying image creation tools.
Users verifying reproducible images should use raw images, verify checksums, and convert them to VHD/VMDK as needed.

Component Updates

Linux: 6.18.2
containerd: 2.2.1
etcd: 3.6.7
CoreDNS: 1.13.2
Kubernetes: 1.35.0
Flannel CNI plugin: v1.9.0-flannel1
LVM2: 2_03_38
runc: 1.4.0
systemd: 259
cryptsetup: 2.8.3

Talos is built with Go 1.25.5.

VM Hot-Add Support

Talos now includes udev rules to support hot-adding of CPUs in virtualized environments.
