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.

HTH,
