Stellaris

Update 2.2.6.3 (15.03.2019)
2.2 ‘Le Guin’ Free Features

    Added a new, more user-friendly planet screen, with better organization and display of info and buttons
    Ship upgrading is now handled individually, on a per ship, per shipyard basis. This means if the process is interrupted part way, some of the ships will still be upgraded, rather than losing the entire upgrade progress. Also, alloy costs are now deducted one ship at a time, rather than for the entire fleet in one go, so you don't have to wait until you can afford everything to start the upgrade process
    Warrior Culture civic no longer reduces army upkeep, but instead makes Entertainment buildings replace Entertainers with Duelists. Duelists turn 1 alloy into 3 unity, 12 amenities and 2 naval capacity
    Added Logistical Corps tradition custom flavour text swap for Hive Minds
    Added Great Game tradition custom flavour text swap for Devouring Swarms
    Added new animation to Plantoid 13 (cactus) portrait. It will now have some butterflies as company!
    Added the Legion flag set with six new selectable flag emblems

Bugfixes

    Fixed edge case where multiple megastructures could be built in the same system
    Fixed missing missions for primitive observation posts

    Fixed guaranteed ideal nearby systems generating based on absolute distance rather than max jumps from homeworld, which could cause them to be isolated by unlucky jump lane network generation

    Fixed vassal integration wrongly costing no influence
    Fixed an issue where conquering Hive Minds could take over inappropriate buildings they have no use for, like Holo-Theatres
    Maintenance drones now correctly increase in priority when amenities are negative, and now don't have increased priority from traits when amenities are high
    Slave processing centers should no longer vanish when build anywhere but a Thrall-World

    Fixed developing colonies being hidden in the outliner's Sectors group if on completion a new sector would be created
    Fixed pre-sapient policies disappearing if you purge all of them from your space, making fulfilment of certain faction demands impossible, because what are the screams of the innocent next to that sweet, sweet influence?
    Changed wording on the Strong/Very Strong traits. It was wrongly implying that is should affect the outcome of ALL worker strata jobs, not just basic resource extraction ones. Even if your clerks never skip leg day, they probably shouldn't benefit from these traits
    Added piracy suppression values to event generated ships that were missing them
    Fixed a few more cases of techs with the wrong specialty group assignment
    Fixed a minor discrepancy in the tooltip of the Sins of a Sun anomaly vs its actual in game effects
    Fixed a nasty exploit with downgrading fleets that could result in free alloys (thanks for the heads up on this, Reddit user nonium)

    Added a basic Zro income to Spiritualist Fallen empires to allow them to properly produce reinforcements for their damaged fleets
    The modifier for Refinery worlds should also now affect Gestalt jobs
    Fixed several ship weapons which had incorrect resource costs
    Energy/Culture Habitat districts should convert properly if a gestalt empire takes it from a normal empire, or vice versa
    Fixed a crash when a country gets a trade route that used to belong to someone else
    Fixed tooltip that hilariously claimed that setting a species to purge (except neuter) was a requirement for the Decent Living Standards

    Fixed a crash when gifting planets to a vassal
    Fixed a situation where replacing a district temporarily adds to the maximum numbers of built districts, as if you were building a new district
    Speed demon event will add the red/green traits even if your species is very strong/adaptive
    Fixed planets under colonization suffering low stability events
    Fixed Crisis purging yet again (for a galaxy-threatening menace they sure seem easy to dissuade from their mission of doom)
