 The upgrade to this version was more extension as there have been migrations to using configuration documents. This required rewriting the configuration document to a series of patches and provide a deterministic generation command for the different host types. In addition there was also a change to storage layout to separate ceph, local-path, and ephemeral storage on the NUC hosts.
