Assuming that 2.18.3 compiles and doesn't have any glaring defects then
that sounds like a fine plan.  DEFAULT_PREFERENCE is, frankly, rather
too blunt an instrument to be of much use nowadays: any DISTROs that
particularly wish to use 2.14.2 should be (and probably are) setting it
as their PREFERRED_VERSION.

All too often we end up with new versions being stuck in at
DEFAULT_PREFERENCE -1 simply because the person updating the recipe
didn't want to take the responsibility for testing it.  This is
something of an unsatisfactory situation and maybe one that the TSC
could address in due course with some kind of policy formulation.
