# Aug 20, 2026 — LKE updates

Existing clusters created prior to [the release on June 22nd 2026](https://techdocs.akamai.com/cloud-computing/changelog/jun-22-2026-lke-updates) have switched from using WireGuard to Konnectivity for communication between the control plane and worker nodes. When upgrading, this will cause a brief outage. Since clusters created after June 22nd are already using Konnectivity, they are unaffected by this change. This release also includes updates to Kubernetes versions.

# Changed

* [Konnectivity](https://kubernetes.io/docs/tasks/extend-kubernetes/setup-konnectivity/) is now used for communication between the control plane and worker nodes on clusters created before June 22nd, 2026.
* Cluster control planes have been updated to the following Kubernetes versions:
  * v1.36 has been updated from  [1.36.2](https://github.com/kubernetes/kubernetes/releases/tag/v1.36.2) to [1.36.3](https://github.com/kubernetes/kubernetes/releases/tag/v1.36.3)
  * v1.35 has been updated from [1.35.6](https://github.com/kubernetes/kubernetes/releases/tag/v1.35.6) to [1.35.7](https://github.com/kubernetes/kubernetes/releases/tag/v1.35.7)
  * v1.34 has been updated from [1.34.9](https://github.com/kubernetes/kubernetes/releases/tag/v1.34.9) to [1.34.10](https://github.com/kubernetes/kubernetes/releases/tag/v1.34.10)

# Upgrade notes

This upgrade will cause a brief outage on clusters created before June 22nd, 2026. See [Upgrade a cluster to a newer Kubernetes version](https://techdocs.akamai.com/cloud-computing/docs/upgrade-a-cluster-to-a-newer-kubernetes-version#manual-minor-version-upgrades) to learn how to upgrade existing worker nodes.
