I haven't seen the new version of Empire yet, but the new commodities you
asked about are:

	dust: gold dust, which gets turned into gold bars if you let it.
	      if you're hard up, it can be contracted for more money than
	      bars (but you're spending your principal).

	lcm:  light construction materials, an intermediate stage between
	      iron ore and things like research and education.

	hcm:  heavy construction materials, intermediate between ore and
	      things like guns and ships.

Note that building some things requires both lcm and hcm;  I seem to
remember that you need dust in something also (atom bombs?).

The net effect is that you need a lot more care in setting up your
delivery routes, since the development process now has more steps.
