If these chapters are merged, I think we will have to rethink the "The
Cutting Edge" title. The title is by itself intimidating for the
beginning-intermediate user who is already convinced it is best for him
to use "RELEASE" until he is comfortable with the system. And using
freebsd-update is essential (and a rather easy task) at any user level.

How about changing the chapter to something like "Updating and Upgrading
FreeBSD"?
The first sections could deal with security updates and minor / major
version upgrades using freebsd-update.
Later sections could deal with -STABLE and -CURRENT
It would probably need more than a few rewrites and reorganization though
