You can find a description of release tags in the handbook.

http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/current-stable.html.
Later bits in that section also describe the update procedure *even if
you are updating to a RELEASE./RELENG rather then CURRENT or STABLE*.
A brief description of the strings in tags is a follows:
CURRENT == bleeding edge
STABLE == merely leading edge
RELENG == what you are calling "stable"; a release plus security patches
only
RELEASE == sort of you are calling stable, exactly what was released
(not recommended since it lacks any security patches)
The latest release is 6.2, so the tag you want in your supfile is
RELENG_6_2. That string won't be in any supfile on your system. It's
impossible for it to be, since that would require predicting what will
be the latest release at the point in the future when you chose to
upgrade :-)
In technical terms, CURRENT is the top of the main development trunk,
and is often referred to with a leading number (e.g. 7-CURRENT), but the
number does no more than denote the numeric tag that will be applied
when the next branch is made. Once 7.0 starts being created, CURRENT
will be 8-CURRENT.
STABLE is the latest branch. Code here will become the next Release.
Moving code from CURRENT to STABLE, involves a CVS merge operation and
is often referred to as MFC - merge from CURRENT.
RELENG is a branch created when a specific release is made. It denotes
the latest code on that branch, but the only changes made will be
critical security fixes.
RELEASE is just the point on the RELENG branch which is the actual code
which was released on the Release CDs.

PS
Be really nice if all this info was clearly in the FAQ, and the FAQ was
searchable apart from the whole website. As things stand, a search for
"stable" returns precisely nothing, which can't be right.
Thank you for the detailed description. Just one last question for
you and the list, what sort of heart ache can I expect to encounter if
I use the label RELEASE_6_2 in my supfile on a system that is 6.0? I
need to upgrade a 6.0-RELEASE (no patches) system. Will I encounter
compiler problems (that is, I'm using a compiler that's older than I
should for 6.2), or similar? Or, should the upgrade be just as smooth
as the run through I just completed on a non-critical notebook running
6.2-RELEASE (or rather, it was running 6.2-RELEASE, now it's
6.2-RELEASE-p4)?
Thanks again,
Andy
