Thanks all for your patience. This was a really long time coming, but sometimes you have to break everything at once to get things into a good state. I had to re-architect pretty much everything, but it's set now. This is definitely the most complex single update I've ever done for a game. I hope it's worth the wait.
TL;DR:
A complete rewrite and redesign of almost everything on the station.
A ton of fixes and improvements to the galaxy map.
A new main quest.
So much optimization. You can now have several thousand people, not just a few hundred.

Mac and Linux: I've heard Wine works well.
Changelog:
Decks:
The station construction system has been redesigned from the ground up. Instead of rooms and furniture, you build buildings. Almost all of them have been expanded or replaced outright.
The station is now split into five decks, each with its own purpose.
The Palace Deck holds the throne, and your personal entertainments.
The Administration Deck holds citizen housing, and the new ministries.
The Pleasure Deck holds hotels, bars, brothels, and all things fun.
The Slave Deck has everything they need, from housing to training.
The Industrial Deck has shipyards, and their infrastructure.
Decks start much smaller than the old station, and have to be built out over time.
Some sections have special features that you will discover as you unlock them.
All decks have different structures, but you can build any structure on any deck if you want to.
Some structures are now unlocked by progress in galactic conquest.
New station characters:
Station characters now use new models. Tourists, citizens, slaves, and the player are now identifiable at a glance, and much better-looking.
Slaves match hair and skin color.
Characters in the station view now have expressions and walks based on training state.
Pathing has been rewritten from scratch. It's more stable, works with the new elevators between decks, and is generally much nicer.
No more aimless wandering.
Citizens go to bed if they have a day off and no entertainment, or leave if they're jobless/homeless.
Tourists just leave if there's nothing to do.
Slaves sit down on the slave deck if they have no work, and pass out if they have no bed.
You sit on your palace floor if you don't have anything better to do.
