+# Kubernetes Operator Support Matrix
+
+## Kubernetes compatibility
+
+The NetBird Kubernetes operator targets the Kubernetes minor versions that are currently receiving patch releases from upstream. The [Kubernetes release policy](https://kubernetes.io/releases/) keeps release branches active for the three most recent minor versions, with roughly one year of patch support each — the operator tracks that same window.
+
+In practice this means the operator avoids depending on Kubernetes APIs or features that are not yet available across every supported minor version. When upstream drops a minor version from patch support, the operator may begin adopting capabilities that became generally available during that version's lifetime.
+
+## NetBird control-plane compatibility
+
+The operator is developed against the latest NetBird control-plane release. Older control-plane versions may continue to work, but compatibility is not actively verified outside the current release.
+
+## Reporting compatibility issues
+
+If you hit a problem on a supported combination, see [Report bugs and issues](/help/report-bug-issues). Include your operator version, Kubernetes version (`kubectl version`), and NetBird control-plane version.

+
+<Warning>
+  The kernel cutoffs below are derived from the [Go toolchain's minimum OS requirements](https://go.dev/wiki/MinimumRequirements) for each NetBird release's Go version. Distribution-specific support beyond the kernel floor is determined by the NetBird team's testing — confirm before relying on it.
