Changed tr_subterfuge_cloaking_finish to cloaking strength 2 instead of 1.
Changed tr_subterfuge_double_agents to envoys_add = 1.5 instead of envoys_add = 1 (double agent counts as 1.5 ;)
In traits, changed species_empire_size_mult = -0.5 to species_empire_size_mult = -0.33.

00_weapons_pointdefence.txt has been deleted, reason: the files were identical even in vanilla.

{
removed ship_data because it was removed in 3.7.2

}

Defines AVERAGE_FLEET_SIZE_FACTOR set to 0.9 instead of 0.5 (3.7 is at 1)

changed action_demand_subjugation and action_ask_to_become_subjugated so that it requires a fleet < inferior instead of a fixed value of fleet_power > 5000, which is ugly.

{
ai_resource_production = {
energy = 1
trigger = {
always = yes
}
}
}
Economic_plans\01_base.txt has been updated with everything from 3.7.4 (it's worse though).

02_gestalt_civics empire_size_mult = -0.20.
civic_brand_loyalty left unchanged.
Deleted observation_station_missions\00_missions.txt because it was the same as vanilla.

Galactic_empire_1 now has country_base_unity_produces_add = 200 instead of country_base_influence_produces_add = 20.

Changed phi_jobs overlord_resources to phi_jobs and added the has_science_ministry modifier effect.
Added all #POLITICS TRADITIONS RESOLUTION to resolutions\00_resolutions.
Changed scripted_effects\01_start_ofgame_effects to:
{
#phi was add_building = building_engineering_lab_1 3.2.2 add_building = building_bureaucratic_1
to that of 3.7.2 because unity is now important.
}
If civic_permanent_employment is active, added building_posthumous_employment_center instead of building_engineering_lab_1, check # phi was g.g add_building = building_engineering_lab_1.
Changed ai_shipdata to carrier.
Added a limit to titan.
Instead of upkeep at 0, ioncannon is now at 1.

orbital ring now has hp 9k-18k-30k.
salvager_workshop now decreases upkeep ship by 40% instead of 20% as per the phi ratio, and cost and maintenance are doubled.
cybrex_mining_hub station_gatherers_produces_mult set from 1.5 to 2.
Removed ai_build_at_chokepoint = yes and ai_build_outside_chokepoint = yes in phi_sublimation_starbase_buildings because they are obsolete.
Changed the ratio of starbase_types\00_starbase_types strading_hub to that of 3.7.2.
