New Features:

+ The Infinite Build Queue

In the launch version of Supreme Commander 2, you immediately paid for units and structures when queued. With this patch, you pay for units when construction starts. While it may sound like a simple change, it changes the way you play the game and manage your economy. It allows you to pre-plan your bases and unit queues beyond what you can afford with your resources at any given time during a game.

With this change, you need to more carefully manage the build statuses of your Engineers and factories, and be prepared to use manual pausing and unpausing, because the least expensive units or buildings queued always get priority. You'll also want to pay more attention to your incoming Mass and Energy reserves so you don't have builders sitting around waiting for resources.

The patch also adds automatic management of Engineers and Factory queues that are waiting for resources to become available. If you queue beyond what you can currently afford, units will automatically wait and continue production when resources become available.

Build Queue details as follows:

+ We now show the rebuild bonus outline, even if you do not have the resources to build the item.
+ Added two new keybinds: Ctrl-Shift-P: Pauses all construction units, Ctrl-Shift-U: Unpauses all construction units.
+ When you pause an engineer or factory they will continue building whatever they are currently building (you already paid for it anyway), but will not start another build task until unpaused.
+ No more yellow outlines when building.
+ If they can afford the unit when the command is issued, they will pay for it right away and move to build.
+ If they cannot afford it when issued they will move to the build site and wait until they can afford it.

Features:

+ Greatly Improved AI handling of NoRush games.
+ Full fix for jumping/teleporting formations of units and only half of them getting the order.
+ Addition of the command line option /reverserightclickmode, which changes the default right-click action to move the selected group to a destination ignoring formation rules. Ctrl-right-click will force the group to use a formation while travelling.
+ Air units now move consistent speeds whether grouped or ungrouped.
+ Improved handling of Engineers/ACU when trying to reclaim things beneath them.
+ The Cybran ACU should no longer get stuck in an unrepairable state.
+ Artillery should once again be able to target things it has had LOS on, but not current radar.
+ Artillery can once again target structures under the Fog of War that you have had previous intel on.
+ Units that do not earn XP from combat are no longer able to consume awarded XP if they get the kill.
+ XP that was improperly awarded in the above case is now properly awarded to valid recipients.
+ Performance improvements by adjusting all buffs that are AoE buffs over time to Refresh instead of Replace.
