+`VERSION_CURRENT` is the upgrade name for the current version. e.g. v6.0.0 is the upgrade name for v6.0.0, v6.0.1, v6.0.0-rc0, etc.
+`VERSION_PREUPGRADE` is the upgrade name for the preupgrade version. e.g. v6.0.0 is the upgrade name for v6.0.0, v6.0.1, v6.0.0-rc0, etc.
+`VERSION_FULL_NAME_PREUPGRADE` is the fully qualified preupgrade version name. This is used in the download url. e.g. v6.0.0-rc0.
