What’s New In Kairos, 2026 Edition
summary
Kairos v4.03 turns Ubuntu, openSUSE and similar distros into immutable, image-based OSes for K3s or K8s and adds a CNCF-hosted distribution Hadron (musl + systemd). Key deliverables: Kairos init one-liner that converts a Dockerfile into a Kairos image, Kairos factory that builds ISOs/raw/cloud images, and Kairos operator that performs node OS upgrades/rollbacks from Kubernetes. Production uses include TPM measured trusted boot for Deep Network devices and Nvidia board deployments for Arya Imaging; project gains external maintainer William Rizzo.
