I belief there are 2 version: 1. The ZFS file system version. This has always been 5 I belief. 2. The ZFS pool version. This changed from 14, 28 to 5000 it seems. The dmesg hints towards that as well: ZFS filesystem version: 5 ZFS storage pool version: features support (5000) It seems that the zpool versioning changed a bit to allow for greater flexibility in what features are supported or not and not have it impact some version numbering.
