Stellaris

Update 2.2.4 (18 January 2019)
2.2 ‘Le Guin’ Free Features

    Added the new "Legion" flag set, with 6 new flag emblems
    Added some missing localization for new 2.2.2 features/fixes
    You can now choose not to care about brain implant problems

Balance

    50 years must now pass before the Galactic Market can be founded
    Xenophile faction now cares about whether any pops are actually enslaved, rather than slavery policy in general
    Increased delay before Caravaneer fleets start roaming the galaxy
    Increased Alloy production for relevant Branch Office buildings from 2 to 3
    Significantly lowered the priority of drone maintenance jobs as they were always chosen before other simple jobs
    Fixed so that newly promoted pops can be instantly demoted if fired within a year of promotion. This should help with cases of pops abandoning basic resource production jobs to take on more specialist roles when the buildings that provide them are activated, crippling your economy
    Lowered Tidal Locked modifier on total available planetary districts from -50% to -30%
    Syncretic species do not increase xenophile attraction
    Biotrophies are now quite upset if they don't have the Bio-Trophy "job" of laying about being pampered
    Changed the size of all sectors to be 3 hyperlane jumps
    Drone Storage building now increases amenities instead of adding a maintenance drone job
    Upgraded Drone Storage building now increases amenities instead of adding 2 maintenance drone jobs
    Drone Storage building effect on housing reduced from 5 to 4
    Priest job weights have been tweaked
    High Priest jobs now also provide 2 society research
    Reduced Devastation needed to destroy Contingency Worlds to 50%
    Debris Analyzed research points per component increased to 20 x level
    Culture Workers, Artisans, Metallurgists, Chemists, Translucers and Gas Refiners have had slight tweaks to their job weights
    Quantum Energy States and Advanced Food Processing technologies no longer require the Colonial Centralization technology
    Quantum Field Manipulation and Nano-Vitality Crops technologies no longer require the Galactic Administration technology
    Gene Crops technology no longer requires Colonial Centralization technology
    Several planetary modifiers now force a good mineral or energy deposit to spawn

UI

    Added missing modifier icons for Improved Code Standards and Production Quota Surpluses
    Fixed incorrect colony type icon on industrial worlds
    Fixed slight visual spillout of the Hive Nexus and Hive Core building icons
    Removed unnecessary and confusing close button from the caravaneer GUI
    Added proper icons for Improved Code Standards and Production Quota Surpluses modifiers, and removed placeholders
    Fixed Branch Office value not displaying if over 99.9
    When researching Paradise Domes/Organic Paradise, only the building your empire type can build will be shown
    Made the Build Megastructure menu a bit less cramped
    Fixed the UI committing seppuku if you clicked the population tab on an uninhabited world

AI

    AI now properly prioritizes starbase types it has too few of; the prime one being a shipyard
    Fixed it so AI can now attempt to counter piracy even when at war
    Made AI a lot less likely to split up its fleets in to portions so small, it then calculates it lacks sufficient strength, and will not attack when at war
    Lowered the threshold for the AI deciding whether or not to attack, so it shouldn't resort to a Fabian strategy of non-engagement in war
    Fixed some AI weights for population control (thanks for the heads-up Glavius, you're rad)
    Fixed AI not repairing ruined buildings when it had the resources to do so
    AI will now actually follow through on its well-intentioned desire to upgrade buildings
    Tweaked alloy budget for fallen empires to better match their needs
    Stopped the AI from spamming redundant colony ships
    Fixed Gestalt empires not building colony ships
    Tweaked budgeting to make the AI less reticent about hiring leaders

Performance

    Performance improvement when computing pop factions
    Performance improvement on modifiers using a hybrid array
    Threaded some fleet calculations
    More pops threading for better performance
    Optimization: will no longer calculate the country modifiers at the end of the planet daily update serial, but have a pass to calculate all countries that were modified after all planet updates
    Optimization: Improved job counting
    Parallelized fleet looking for combat for slight performance increase
    Added more threading to planet handling
    Optimized population calculations some more, reduced unnecessary calculations
    Reduced amount of systems the outliner needs to check for planets to populate planet and branch office lists
    Adjusted amount of extra rendering for micro and daily ticks

Modding

    Ecumenopolises now have properly-set graphical cultures
    Updated the is_organic_species and is_robotic_species scripted triggers to use the new is_archetype trigger, to better support modded species classes
    Added "purge = purge_type" to job types. Pops doing that job are getting purged in the type indicated (purge_normal, purge_matrix, purge_neutering, purge_displacement, purge_labor_camps, purge_processing )
    Added "purge = purge_type" to pop categories. Pops in that category are getting purged in the type indicated (purge_normal, purge_matrix, purge_neutering, purge_displacement, purge_labor_camps, purge_processing )

    Updated the Dessanu L-Gate outcome from Distant Stars to properly work with the 2.2 resource rework. It will now provide monthly rare resources
    Fixed some instances of orbital deposits being wrongfully placed on habitable planets, via anomalies or events (Silent Behemoth, Cunning Flora, Echoes From The Deep, etc). Also replaced some of these cases with usable planetary features
    Fixed a Vengralian Trium caravaneer deal's description text wrongly promising a 10% trade value increase, when the tooltip and gameplay result is 15%
    Fixed newly added democratic mandates not registering progress on them correctly, making them impossible to fulfill

    Disabling sector automation now REALLY disables it. Previously it would continue to build if it had resources left. Good initiative, but...
    Fixed tooltip for the Fender Bender anomaly stating it grants 9 eng research when in fact it only gives 3
    Fixed tooltip for the Rudimentary Robots anomaly stating it grants 3, when it actually gave out 2, by just saying "hell with it give 4 instead"
