Is this intentional? I think for our latest stack we need a Kata 3.28 release.
I don't know what 'v0.18.0' is here and I ma not sure if we have the exact trustee/guest components in these versions. We are not using a concrete CoCo release. We are using a Kata release and this Kata release pull in CoCo components as dependencies
