That's a bit confusing :( The reason is that "version" is a one-dimensional number allowing for only a single controlling authority (Sun) who defines what a version means (in terms of features). So instead, Illumos decided to abandon it (setting it to an arbitrarily high number to avoid conflicts with intervening Oracle ZFS releases which continue to use the "version" property) and instead using the so-called "feature-flags". See http://blog.delphix.com/csiden/files/2012/01/ZFS_Feature_Flags.pdf for a more detailed description.
