Actually, if there is no "most important" item in a section, I just
order by placing the largest group of similar items first.  Here are the
detais:

	https://wiki.postgresql.org/wiki/Creating_Major_Release_Notes
	order inside of sections
	               most important item first in section
	                  if none, then largest group first
	               group similar items together
	               order group by item importance
	               ideally the last item in a group will relate to the first item in the next group

  Do not let urgent matters crowd out time for investment in the future.
