Yes, this probably should have been mentioned in UPDATING.  Oddly, it
did make it into the 8.1 Release Notes.  A complicating factor for
those using packages from the FreeBSD build cluster is that the
packages for 8* (i.e., packages-stable or packages-8-stable) are
usually built on some version of the oldest supported security branch
of 8, so for a period of time after the addition of xz to 8-stable
those packages included an unnecessary dependency on archivers/xz for
users of 8-stable, 8.1, and 8.1-stable.  Fortunately, in this case,
there probably wouldn't have been any adverse effects, other than a
small waste of space and some confusion.
