Balance

    Pop growth: Reduced Random factor in pop growth, habitability has more of penalty on growth selection, lessened bias towards new species, and traits have a larger effect on Robot selection
    Strike craft now do more damage, have longer range, are faster, and turn and accelerate quicker
    Machine Empires get 50% more resources from mining bases
    Machine Empire Tech Drones now produce 6 energy (up from 4) base. Agri Drones now produce 5 food (down from 6) base. Both of these also apply to Synth Empires.
    Machine Empire Colony ships now add 2 pops to a new colony, but cost 400 alloys (up from 300)
    Machine Empire Outposts now cost 150 alloys
    Machine Empire Fabricators produce 4 alloys (up from 3) at the cost of 8 minerals (up from 6).
    New Machine Empire colonies start with 2 replicator jobs to give a bit of early boost (up from 1), upgraded capitals reduced to give the same number overall. The extra Replicator jobs beyond the 2 granted by upgraded capital buildings now depend on the planet still having >= 10/40 pops, to remove a tedious exploit with resettling pops to unlock the upgrade, then moving them again
    Machine capital planet grants +5% drone output
    Unemployed Machine Pops now use 0.25 Energy for upkeep (down from 1)

    Field Modulation, Quantum Energy States, Quantum Field Manipulation technology effect on technician output increased from 10% to 20%
    The Repugnant/Uncanny trait now has less of an effect on pops avoiding amenity producing jobs
    Maintenance drone job priority now considers amenity level of the planet
    Simple drones now ponder the empire level food/mineral/energy income when choosing a job

    Fixed tooltip that wrongly stated that only full citizens can take ruler jobs

    Fixed broken string in tooltip for event option you absolutely should not click, you have been warned

AI

    Machine and Mechanical AI empires will favor generator districts a bit more
    AI will not build housing buildings when it doesn't need them
    AI will no longer start scrapping buildings immediately once it decides it doesn't need more of them, it will just stop building new ones for a while
    Improved AI budgeting for megastructures
    AI empires will generally not build more than 2 buildings of the same type per planet
    AI should be keen on building Organic sanctuaries if their bio-trophy pops are unemployed
    AI only becomes more interested in building commercial zones if it needs energy and amenities (was previously overbuilding these)
    AI will check for surplus population before making buildings
    AI now budgets the full total available resources into categories

Bugfixes

    Fixed broken targeting for strike craft that caused them to meander out to the edges of the system rather than engage enemy fleets
    Fixed some Planetary Features (and thus Districts) not surviving the terraforming process to Gaia planet class, because what's a paradise planet if you can't strip mine it and turn it in to a honeycombed shell?!
