K3s has released version v1.34.2+k3s1, bringing the lightweight Kubernetes distribution up to Kubernetes v1.34.2 with numerous bug fixes and component updates. The release addresses critical networking issues including a fatal error when changing node IP addresses and improved IPv6 handling for load balancer addresses.
The update includes significant improvements to server stability with fixes for shutdown sequencing, etcd member promotion, and server token rotation. Component upgrades span the entire stack with Traefik bumped to 3.5.1, CoreDNS to 1.13.1, and runc to v1.3.3. The release also updates Flannel, kube-router, and CNI plugins alongside improvements to the Klipper Helm and Helm Controller components.
Under the hood, K3s v1.34.2+k3s1 ships with etcd v3.6.5, containerd v2.1.5, and Flannel v0.27.4. The project has also migrated its release pipelines to GitHub Actions and implemented various backend improvements including fixes for Kine metrics registration and Postgres object count handling. K3s continues to be developed by Rancher as a CNCF-certified Kubernetes distribution optimized for edge computing and resource-constrained environments.
