There is no Proportions for 1.49. There are some important new features in Gold that allow some things that would not be possible in 1.49.

Mainly, MM implemented a couple of requests I had for population - in Gold, you can specify the mass and reproduction frequency of population units. You could rationalize that population represents only skilled specialists and abstract development, but it would have a major effect on gameplay (these two factors combined with the Proportions population effect curve make a world of difference in colonial development rate).

Also, the massive amount of work that I, John and Oleg have done to create AI's that can build ship classes with the right number of engines, and bunches of other AI adjustments, would mostly be lost and have to be redone for 1.49.

It would be so much work that it makes no sense compared to the price of Gold, and Gold is really worth the cost to upgrade!
