The main thing in this update is to add the special unit buffs, which provide an additional way of increasing the potency of the player's fleet without simply adding more units. These buffs are also available in regular skirmish games via random crates (the collection method is similar to the Command and Conquer games.)

The addition of the new mouse over panels in the campaign menu was also an important addition, as it lets new players know at a glance what each of the units in their fleet looks like and what its general role in battle is.

I also made some changes to the income rate from territory in the Fleet Conquest skirmish mode to reduce the problem of snowballing incomes in the late game. I haven't done much with that mode lately as the campaign has more or less replaced its role as the longer term repayable game mode with persistent fleets. The campaign seems to be the more well liked mode in general, but I want to make sure all of the current game modes are as fun as possible.
