The entries themselves, no.  But it did seem to me that the approach to
which things go in what files -- as exemplified by the default sample
configs -- changed a bit, no?

Or do I just think that because the "segregate in cfg_dirs by type of
object; everything in its own file" approach made more sense to me?

Yeah, so I found out; see my other reply.

I did see that, when I actually looked far enough.  :-)

For what it's worth, it doesn't *actually* say that if you are going to
declare an object a member of a hostgroup, you *do* still actually have
to *define* it somewhere, which it probably should.  Certainly it's
implied, but I'm not sure that's good enough, as complicated as Nagios
is.
