ClusterStack releases and Kubernetes versions
ClusterStack releases and Kubernetes versions#
Every ClusterStack release ships a specific patch version of Kubernetes. The table below maps each hetzner-apalla ClusterStack release to the Kubernetes version it provides, together with its release date — so you can see at a glance which release corresponds to which Kubernetes version.
By default the table shows the latest ClusterStack release for each Kubernetes minor version. Choose Show all releases to expand the full history.
| Kubernetes | ClusterStack release | Kubernetes version | Released |
|---|---|---|---|
| 1.35 | hetzner-apalla-1-35-v4 Latest | v1.35.7 | Jul 27, 2026 |
| 1.34 | hetzner-apalla-1-34-v10 Latest | v1.34.10 | Jul 27, 2026 |
| 1.33 | hetzner-apalla-1-33-v13 Latest | v1.33.13 | Jul 27, 2026 |
Note
A single Kubernetes patch version can be shipped by more than one ClusterStack release — a newer release often adds fixes or addons without bumping Kubernetes itself (for example, several 1-32 releases all ship v1.32.13).
Planning an upgrade#
Upgrades follow tested upgrade paths, and you cannot skip more than one Kubernetes minor version at a time. To upgrade your cluster step by step, see:
- Update within the same Kubernetes version — move to a newer ClusterStack release while staying on the same Kubernetes minor version.
- Update to a new Kubernetes version — move to the next Kubernetes minor version along a tested upgrade path.
Tip
For the guided, step-by-step path from the exact version your cluster is on, open the version selector at the top of the navigation and select your current version. Autopilot will then lay out the precise sequence of releases to upgrade through.
Updating Kubernetes version
Update your Kubernetes cluster seamlessly to the latest version, ensuring optimal performance and enhanced features for your environment.
Adding HCloud servers
Efficiently manage Hetzner HCloud servers. Choose the server types according to their individual specifications based on your requirements, such as resource-efficient ARM technology.
