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 will be somewhat more minimal.
The latest snapshots made available are the following:
If a snapshot for your architecture or the version of FreeBSD that you require is not available from the directories above, older snapshots are usually available from ftp://ftp.freebsd.org/pub/FreeBSD/snapshots. It is worth checking there to see if a snapshot that meets your need is present.
Currently the snapshots of 7-CURRENT, 6-STABLE, and 5-STABLE are released monthly in URLs in the format ftp://ftp.freebsd.org/pub/FreeBSD/snapshots/<month>_<year>/ where <year> is the year, <month> is the month the snapshot was released. Each snapshot directory might contain a RELNOTES.TXT file which outlines the changes for the particular snapshot.
In particular, before getting and installing a snapshot release, be aware of following:
Your feedback on these snapshots is, of course, greatly welcome. They are not just for our benefit - those who are coming to rely on FreeBSD for mission critical applications should welcome a chance to get at more updated bits in a structured fashion. You can also use these snapshots as tangible evidence that your feedback is getting incorporated and that you (hopefully) will not have any unpleasant surprises in the next release. On the other hand, if you do send us hate mail next release and it turns out that you never even tried the snapshots, well, it cuts both ways!
Here are some related resources. Note that they are managed by other people than the FreeBSD Release Engineering Team. These sites provide FreeBSD snapshots in a form of "live filesystem" and bootable ISO images on a daily basis.
