This one responds to most of the remaining feedback from the last round of polls. Specifically:
The Zenith/Spire starships got their long awaited promotion into two new separate lines of starship. The Player Home Forcefield Generator got grav and tachyon coverage (and two semi-related issues with home defense were addressed). The Spire Stealth Battleship was made a little easier to catch (mainly this helps handle AI-controlled ones), and Spire Shield Guard Posts won't take so long to kill. And there was one other...
Ah, yes, the Botnet Golem. Long believed to be the most overpowered unit in the game, things weren't looking good for the Botnet. But thanks to some players reminding us how much fun that overpowered golem is, a (hopefully) better solution was reached: the botnet has retained all its power but is now its own minor faction. It functions basically as before but now we can balance it separately from the rest of the golems.
There's also a few other changes and fixes (golems/spirecraft exos are now more aggressive in general, notably), so look at the notes if you're curious :)
