I'm going to start posting more detailed patch notes here whenever I update:

(I also just started using the itch.io butler tool, which should make downloading future updates easier)

-added several new possible missions for campaign nodes including some that load different missions depending on the player's relationship with a certain faction
-added a new store type for trading specific ship types with another faction
-updated union cruiser portraits to match the current model
-improved formation drawing system to better handle non-linear shapes
-formation drawing system is now more accurate at keeping units at their desired destination, when bumped by other units
-formation breaks no longer draw the white formation lines when being placed
-added a new variation of the pause menu for campaign missions that allows the player to forfeit the current mission
-AI players with high confrontation values now regroup before engaging enemies in most situations
-removed repair hangars from cruisers (mostly to balance the campaign)
-added capturable scrap collector turrets (used in a campaign mission and the first skirmish map)
-tractor beams no longer move building modules
