I have noticed that FreeBSD mini iso no longer distributed but I found interesting link : FreeBSD snapshots From FreeBSD site :
As part of an ongoing effort to improve the overall release process before a release actually slips out the door with problems, we are now periodically producing interim test releases called snapshots. These snapshots will be very similar to full releases, except that they might not include all the bits included in a full release (such as packages and updated documentation).
for example tracking status for ZFS in FreeBSD current available in snapshots, also stable version of FreeBSD 6.2, cool I click on 200705 for latest snapshots : wget time 🙂
