Empty-looking “not in the published matrix” cells were not listed by the project. They are not a guess that the combination fails.
Notes
Minor releases are supported until 6 weeks after the N+2 minor. The control plane may be one version ahead of the data plane; the data plane must not be ahead of the control plane. Helm charts in the 1.32.0 tag include istiod, base, and gateway. Only the istiod chart name is used for matching, because base and gateway are generic names.
