Existing clusters created prior to the release on June 22nd 2026 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 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 to 1.36.3
  • v1.35 has been updated from 1.35.6 to 1.35.7
  • v1.34 has been updated from 1.34.9 to 1.34.10

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 to learn how to upgrade existing worker nodes.
