Lifecycle Policy
The following defines vCluster's lifecycle policy for releases and maintenance.
vCluster aims to release on a regular cadence and follow semantic versioning. We encourage users to run the latest stable release to stay up to date on features and security patches.
Due to the rapid development of vCluster, each minor version is actively supported for 3 months after it's been released. At the end of active support, it moves to into maintenance support for 3 months. During active support, any updates on the active development branch can be backported upon request. During maintenance support, backporting is limited only to security updates.
Any previous versions which are not on this list are no longer in any support window.
Due to vCluster's rapid development, each minor version receives active support for 3 months after its release. After this period, it transitions to maintenance support for another 3 months, during which only security fixes are applied.
Versions not listed under active or maintenance support are no longer supported.
vCluster releases​
| Release | Released | Active Support End Date | Maintenance Support End Date |
|---|---|---|---|
| v0.24 | March 18, 2025 | June 16, 2025 | September 14, 2025 |
| v0.23 | February 26, 2025 | May 25, 2025 | August 26, 2025 |
| v0.22 | December 18, 2024 | March 18, 2025 | June 18, 2025 |
| v0.21 | November 11, 2024 | February 11, 2025 | May 11, 2025 |
| v0.20 | August 14, 2024 | November 14, 2024 | February 14, 2025 |
| v0.19 | February 12, 2024 | April 1, 2025* | July 1, 2025 |
* Extended support: Due to the number of breaking changes from v0.19 to v0.20, the active support period for v0.19 has been extended. Review the migration guide to upgrade your v0.19 virtual clusters to v0.20.
- End of Support (EOS): The date when active support for a version ends. After this date, the version only receives critical security updates.
- End of Life (EOL): The date when all support, including security updates, ends for a version.
Kubernetes compatibility matrix​
The following matrix shows the compatibility between host and virtual clusters when both are using vanilla Kubernetes. It indicates which versions of vanilla Kubernetes on the host cluster support which versions of vanilla Kubernetes on the virtual cluster.
