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 rapid development, each minor version receives active support for 3 months after its release. Active support ends on the End of Support (EOS) date. After the EOS date, the version enters the End of Support (EOS) period, during which only critical security updates are backported. After the End of Life (EOL) date, the version enters the End of Life (EOL) period, during which no updates are provided.
During active support, updates from the active development branch can be backported upon request.
Versions not listed under End of Support (EOS) or End of Life (EOL) are considered unsupported.

| 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 period when active support for a version has ended and only critical security updates are provided. This period begins on the EOS date and lasts 3 months.
-
End of Life (EOL): The period when all support, including security updates, has ended for a version. This period begins on the EOL date and continues indefinitely.
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.
