v1.26.X
Before upgrading from earlier releases, be sure to read the Kubernetes Urgent Upgrade Notes.
Release v1.26.9+rke2r1
This release updates Kubernetes to v1.26.9.
Important Note
If your server (control-plane) nodes were not started with the --token CLI flag or config file key, a randomized token was generated during initial cluster startup. This key is used both for joining new nodes to the cluster, and for encrypting cluster bootstrap data within the datastore. Ensure that you retain a copy of this token, as is required when restoring from backup.
You may retrieve the token value from any server already joined to the cluster:
cat /var/lib/rancher/rke2/server/token
Changes since v1.26.8+rke2r1:
Release v1.26.8+rke2r1
This release updates Kubernetes to v1.26.8, and fixes a number of issues.

Changes since v1.26.0+rke2r1:
- Bump containerd to v1.6.14-k3s1 (#3746)
- The embedded containerd version has been bumped to v1.6.14-k3s1. This includes a backported fix for containerd/7843 which caused pods to lose their CNI info when containerd was restarted, which in turn caused the kubelet to recreate the pod.
- Windows agents now use the k3s fork of containerd, which includes support for registry rewrites.
Release v1.26.0+rke2r1
⚠️ WARNING
This release is affected by https://github.com/containerd/containerd/issues/7843, which causes the kubelet to restart all pods whenever RKE2 is restarted. For this reason, we have removed this RKE2 release from the channel server. Please use
v1.26.0+rke2r2instead.
This release is RKE2's first in the v1.26 line. This release updates Kubernetes to v1.26.0.
