PDX-Loke · May 27, 2025

Greetings all,

Another patch is ready for you to download and apply to your copy of Stellaris, improving the gameplay experience in a variety of ways.
4.0.14 is now available via Steam, and soon also on GOG and MS.

Please find the patch notes below.

Stellaris 4.0.14 Patch

Balance

Fixed Hollow Bones being 1/10 as impactful as it should be. Stay away from big planets birds.
Incubators modifiers will now be a bit more granular and not go from 30% bonus to -10% growth with 40 pops.
Colony Auto-designation now better takes Urban districts into account for flipping to the various Urban-related designations. (We still recommend picking the one you want though. This was mostly intended for the AI)
Gestalt empires can now build trade modules on starbases
Non-gestalt empires can now build solar panels on starbases
Added Logistic traditions for gestalt empires
Split Enforcers and Telepaths
Refactored the psionic pop output from telepaths to be on the psi corp building instead
Introduced Job Efficiency for Psionic Pops modifier where appropriate
Added Job Efficiency for Mechanical and Machine Pops modifier and implemented where appropriate
Added Job Efficiency for Cyborg Pops modifier and implemented where appropriate
Added Job Efficiency for Organic Pops modifier and implemented where appropriate
Empire and Planet Limits for Fallen Empire Buildings now have the following rules:
- If you stole the plans through artifact diving or were gifted them by the Hive FE: Empire/Planet Limit = number of times you rolled the building, capped at 3
- If you got the tech through Enigmatic Engineering: Empire Limit: Uncapped, Planet Limit = 3
- If you have Cosmogenesis: Empire Limit: Uncapped, Planet Limit = 6
- If you’re a Fallen Empire: Empire/Planet Limit: Uncapped
- Note: It is our intention to replace this with a system that turns Fallen Empire building techs into Repeatable Technologies that base the maximum number of how many you can have be tied to the number of times you have researched it. This is likely to be in 4.1, though may sneak into a late 4.0 patch.

4.0 Phoenix Features

Planetary Economy rework

Planets produce and consume resources through Jobs.
Districts provide Jobs based on their development.
District Specializations dictate what Job types are provided by Districts and what buildings may be built.
Buildings typically modify the output of the Jobs.
The Ruler Stratum has been renamed the Elite Stratum, to better differentiate them from the actual Empire Ruler
Pop Groups & Workforce
Pops are now grouped together based on Species, Strata, Ethics, and Faction.
Pop numbers have been increased by a factor of 100, allowing more granular manipulation of Pops by various systems.
Pops produce Workforce that fills up Jobs.
A Civilian stratum has been added to represent the masses that do not generally contribute to the empire’s military economy.
Pop growth reworked
All Pop Groups on a planet have simultaneous growth every month following the existing Logistic Growth formulas.
Underrepresented pops are no longer given population growth bonuses.
Fractional growth is not retained from month to month - if a Pop Group would have fractional growth, it has a chance to gain 1 pop that month based on that fraction.
All migration is now handled through the auto-migration system rather than push and pull that previously affected pop growth.
The minimum growth for small colonies has been removed. Early colonization will be reliant on migration from the empire capital.
Migration pacts now apply to auto-migration.

Empire Focuses and Timelines

The Empire Timeline keeps track of important milestones of a playthrough, available in a tab in the Situation log view.
Empire Focus Tasks introduces short and medium-term goals for players to strive for, and offers an alternative way of unlocking key technologies.
Empires can choose between Conquest, Exploration, and Development as their primary Empire Focus, affecting what type of tasks are drawn.
Completing Tasks provides progress towards Guaranteed Technology unlocks that are considered critical for that playstyle.
Task completion is retroactive and will award progress if drawn.
Tasks may be discarded for a small cost in Unity.
Trade revamped into a standard resource
Trade is now used as the Market currency.
The Trade Routes system has been removed.
Trade Production and Policies are now available to Gestalt’s through Logistics Drones
Traditions, buildings and districts that previously affected maintenance drones now affect logistics drones
Ships now have logistical upkeep paid by Trade
Based on whether they are docked (free), friendly space (reduced), neutral space (normal), or hostile space (expensive).
Larger ships have higher upkeep.
Juggernauts do not have logistical upkeep, and reduce the logistical upkeep costs for ships in their system by 75%.
Planets now have logistical upkeep paid by Trade based on their local resource deficits.
Local deficit costs vary based on the base market value of the resources.
Trade Policies can set how much of your Net trade after logistics upkeep is converted into other resources.
Added galaxy setup sliders for Fleet Upkeep Logistics Costs and Planetary Deficit Logistics Costs.

Branch Office Refresh

All Branch office buildings have been reworked to provide more interesting jobs to their host planet, increase local trade value, and their output now scales with branch office value.
Branch office buildings are now all planet unique. The amount of building slots remains unchanged.
Branch offices can now be opened on other corporate empires.
All buildings now have an influence cost, doubled when building on another corporate empire.
Most Corporate Civics now buff a specific branch office building, increasing its trade value bonuses and adding jobs to their capital planet.
Added new branch office buildings: the Industrial Subsidiary and the Private Security Company.
Criminal Syndicates can now establish commercial pacts, replacing their criminal buildings with the regular version. Regular buildings still provide a crime floor to the host planet if they are owned by a criminal empire.

Databank Game Library

The main help button now displays the Databank where you can explore brief articles on many in-game concepts.
With this effort, many aspects of the game’s UI have been filled with concepts, helping new players understand core mechanics.
Clicking an underlined link in the UI of a concept that’s in the Databank opens that article and filters other related articles.
The full external wiki is still accessible from a button in the Databank. Clicking it on the Databank start page opens the wiki start page. If a Databank article is selected, that article is opened in the wiki.
10 new Mammalian Portraits added to the base game
The Hard Reset Origin added to Synthetic Dawn
Play as soldier Cyborgs, recently disconnected from your Driven Assimilator Overlord

Improvements

Colonization flow has been improved.
You can now pre-select a colony designation and turn on planet automation before colonizing a planet, which will apply when the planet has finished colonizing.
Colonization now completes when 100 colonists have grown or migrated to the new planet.
Significant improvements have been made to the Species UI.
One template per species can be set as the default template for that species, and other subspecies can be set to integrate over time into that default template.
The trait selection UI when creating a new template has been improved.
The special project window pops up and can be started immediately after creating a new template if desired. It is no longer absolutely necessary as you can use integration to slowly convert your existing pops.
The Habitable Worlds slider in game setup now has a 'Rare' setting. There will still be a handful of habitable worlds in the galaxy, mostly from special events and guaranteed habitable worlds. Normalized initializer spawn odds to use a handful of scripted variables.
Added galaxy precursor selection to game setup.
As it no longer creates hybrids and thus no longer contributes to the inevitable decay of society (and framerate), removed the Xeno-compatibility toggle from Galaxy Settings.
Added the Solarpunk City Set for all owners of the First Contact DLC
Added the "Venerable Scientist" (Mandarin Language) Voice Advisor
Added a Galaxy Settings slider for Cosmic Storm Devastation Intensity
Added sliders for Fleet Upkeep Logistics Costs and Planetary Deficit Logistics Costs.

Leader Adjustments:

As part of our game pacing and interruption reduction pass, leaders now gain trait selection moments on even levels rather than every level.
The Under One Rule Luminary still gains leader traits every level.
Leader positions now have a significantly greater effect on what traits will appear when they level up and gain a new skill.
Increased the base number of leader traits to pick from on level up by 1. This is intended to reduce the chance of getting exclusively poor trait options without devaluing other sources of leader trait picks too much.
Added an "Auto Select Leader Traits by Default" option to game settings, which defaults to Off. On game start or if you switch to an empire, it will toggle the setting on the Leaders tab to your selection. In Coop empires, this override only applies when the primary player of the country joins it. Changing the setting mid-game will not have any effect unless you switch countries.
Leader positions now have a significantly greater effect on what traits will appear when they level up and gain a new skill.
Adjective leader trait names reverted, for example Inquisitor to Inquisitive

Added job game text functionality to hook up with scripted job swaps. You can do job_key.XXX, Planet.job_key.XXX or Country.job_key.XXX, where XXX is GetName/GetNamePlural/GetIcon. (So e.g. "My miner name: [miner.GetName]")
City Sets no longer require Ships Sets to be defined, see Wilderness or Solarpunk as an example

Jobs, Districts, Buildings, and Specializations
Added tags to jobs, allowing us to easily group them for use in triggers num_pops_with_job_tag and num_country_pops_with_job_tag.
Districts now support a list of specialization slots defined in zone_slots = { }, these slots define which specializations are valid in this district.
If start = <specialization_name> is defined for a zone_slot, the specialization slot will automatically include this specialization.
Zone Slots have include = { } and exclude = { } lists, typically held in inline_scripts which define which specializations are valid in the zone slots
District specializations are built in zone slots inside districts and have building slots, defined by max_buildings = int
Valid buildings for district specializations are defined by using any of the included_building_sets, excluded_building_sets, include, and exclude lists. Note that exclusion takes precedence over inclusion.
Buildings must now belong to at least one building set.
District specializations also support district_planet_modifier and triggered_district_planet_modifier which are planet scope modifiers that are automatically scaled with the number of districts on the planet of the same type that the district specialization is in.
When a resource is spent to build a building or enact a decision, it is stored locally and can be accessed in script such as “on_queued” and “on_unqueued”, see Wilderness buildings for an example
Biological Ships:
Added a new scope "ship growth stage" or "growth stage" for short. Used for the sub-designs of stages that grow. Ship Designs contain everything that is true for all designs, while Growth Stages contain everything that's related to a specific Ship Size. Triggers have been updated.
Added the "add_evolution_progress" console command, that adds evolution progress to all bioships in a fleet.
You can now specify "growth_stage" in the "create_ship" effect to set the growth stage to use at creation (starts at 1)
Added bioship_can_grow trigger to evaluate if a bioship has the potential to get growth progress
Added target_focus parameter to ships and components to control if it focuses fire or spreads it among targets
Added on_hit effect for weapon component templates
Added repair_shield_percentage, repair_amount, repair_armor_amount, repair_shield_amount effects
Added the has_armor_percentage and has_shield_percentage triggers
Message Scripting:
There is now an event_message_type in events that lets you override the default message type EVENT_MESSAGE_TYPE. This can e.g. provide separate message settings.
create_message target supports faction scope (clicking the message will open the factions view with that faction selected if it is listed).
create_message target supports federation scope (clicking the message will open the federation view if the player is in a federation).
Message notification background is now separated from the message type icon.
Species Trait Tags:
Species traits now support tags, similar to ship weapons. These are primarily used for the new triggers listed below as well as the new add_random_species_trait in the modify_species effect.
To see how this is used check the “add_random_trait_evopred” effect in the biogenesis_effect.txt file.
Added new field localized_tags to species traits used to show the corresponding categories in the trait tooltip
You can now add one or more `portrait_override` to trait, in case you want specific exceptions to the archetypes and species classes limiters. For example, if you wanted to make an egg laying, flat tailed, funny lookin, fast swimming, warm blooded duck billed web footed burrow digging p p p p p p platypus.
Added `species_class_override` and `archetype_override` triggers to trait. If those triggers return true, then the trait ignores the associated requirements (species_class or allowed_archetype)
Added "trait_has_all_tags" trigger that returns true if the trait in the scope has all the traits in the list
Added "trait_has_any_tag" trigger that returns true if the trait in the scope has at least one of the trait in the list
Added "trait_has_tag" trigger that returns true if the scope trait has the tag used for the trigger.
on_actions:
Added the on_resolution_vetoed on action.
New on_action on_favor_gained that gets triggered when a country receives a favor.
New on_action on_research_option_added that gets triggered every time a new permanent research option is acquired.
Add on_ship_enter_fleet and on_ship_leave_fleet on actions
Added the on_resolution_put_to_vote on action
Game Rules:
Removed unused can_resettle_planet game rule and renamed can_resettle_planet_no_owner_check to can_resettle_planet.
Removed can_colonize_with_pop game rule and moved its checks to can_colonize_with_species.
Added should_leader_gain_trait_every_level game rule.
Added the species_has_uncapped_habitability_on_planet game rule, this sets the habitability ceiling for a species to use the HABITABILITY_CEIL_UNCAPPED define instead of the HABITABILITY_CEIL define
Created new rule can_uplift for species
Added the will_leader_survive game rule that replaces the leader death toast with a survival one.
Added the should_colonize_use_terraform game rule, used to get the behavior Wilderness has with terraforming
Added the should_hide_pop_group_size and should_hide_planet_sector_pop_amount which Wilderness uses to obfuscate the amount of pops on a planet
Added the script effect "copy_traditions_from = { target = FROM exceptions = { tradition1 tradition 2 } }" that copies tradition from a target country into the scoped country
Added "add_ascension_perk" and "remove_ascension_perk" effects, scope must be a country, adds or removed the specified perk syntax: add/remove_ascension_perk = perk_key
Added "copy_ascension_perks_from" effect: Copies the Ascension Perks of the target country into the scoped country. They are added to the existing perks, and the potential/possible triggers are respected. The perks listed in the exceptions list are not copied. copy_ascension_perks_from = { target = FROM exceptions = { perk1 perk2 } }
Added "remove_tradition" effect. Remove the target tradition from the scoped Country. remove_tradition = tradition_key
Added effect "remove_tradition_tree" Remove the target tradition tree from the scoped Country. remove_tradition_tree = tradition_category_key
Added spawn_design to static galaxy system data, which forces a specific design to spawn in the system.
Added gamesetup_settings script for configuring the settings list in game setup.
Scripted loc can now be used in concept tooltips and the top bar tooltips.
Added the used_defense_platform_capacity_percent trigger, letting you check how much of a starbases defensive platform capacity is used.
Added "playme" console command as shorthand for human_ai and ai_ignore_was_human.
Added auto_trait_prio support for planet classes
TerraformLinks resource block now has the planet as from scope
Added desc parameter to top bar multi-resource groups.
Added spawner_planet event target link for armies to replace the old pop link
Added parameter to Fallen Empire scripts to prevent using custom empire designs, see the Fallen Hive Empire for an example
Added parameter to force the spawning of neighbors on system initializers, see the Fallen Hive Empire for examples
Added support for leader class-specific skill level modifiers.
Added support for triggers in starbase_level pictures
Added "city_graphical_culture" triggers that test a given graphical culture (or that of a target scope) against the graphical culture used for the scoped country. If the target is also a country, it compares both the graphical cultures used for cities
Graphical cultures now have `ship_selection_weight` to calculate their chance of being picked by empires
The "graphical_culture" trigger now works on species (return the culture associated with the species class) and can take a target, so like "graphical_culture = FROM" will return true if 'this' and 'FROM' have the same graphical culture
You can now specify a global design when creating a starbase, but it only works for designable starbase size (ie the space citadel)
Orbital and Planet Deposits now support habitat_modifier, which as you might expect from the name, applies a static modifier to the habitat(s) in the system.
Added a update_node_portraits_if_gestalt_effect scripted effects
Added documentation to the common/global_ship_designs directory
Added keyboard shortcuts to scripted actions
Support setting animation state from scripted action
Added support for the shipclass_military_special to use cloaking
Modifed Empire Creation so it can handle normal in-game triggers. Removed local_human_species_class and local_human_origin triggers that were used in this context.
dynamic_capacity can now be used for all resources not just those that use special_max_amount
Moved AI only origins into their own file
Added trigger parameter allowed_planet_classes_override to traits in order to override planet classes listed by allowed_planet_classes
Added ai_should_not_restrict_system game rule
Set ideal planets to also provide +100% Habitability so they work nicely with uncapped habitability
Allowed using custom tooltips for forbidden peace offers in war goals
Removed the "attraction_label" from the outliner UI to make more room for faction production.
added "system_modifier" and "triggered_system_modifier" to jobs to have modifiers that are transmitted inside the same system.
added "can_always_dismantle" flag to starbase levels to indicate a starbase type should always be destroyable
Added the inner_radius trigger to determine the size of the gravity well of a solar system
count_species_traits trigger now only filters by category when one is passed as a parameter
Since we build the citadel anywhere, we needed a way to set its position. the easiest way was to do it in code, so now when you've set a starbase in your megastructure, the code will generate it automatically. However the megastructure will not be destroyed by code, so if you want to do that you still need to do it manually.
build_outside_gravity_well flag in megastructures is deprecated, replaced with `build_type = inside_gravity_well/outside_gravity_well/around_planet` used to determine where and how to place a megastructure
Added scripted triggers for has_purity_ascension, has_cloning_ascension and has_mutation_ascension
Added the can_add_mutation_traits scripted trigger
Added is_purity_authority, is_cloning_authority and is_mutation_authority scripted triggers
Added the generate_new_species_and_pop scripted effect to quickly add new species and pops to a planet.
Unified all variants of the assorted plantoid and lithoid traits into single traits using the species_class_override parameter for species traits.
Added the colony_age_years trigger
Updated thrusters, FTL Drives, Cloaking Devices, Ship Reactors, Combat Computers and probably more to use scripted triggers
Added custom_tooltip_with_modifiers support to starbase buildings and modules
Added the upgrade_path parameter to ship components. For core components, components that have the same upgrade path are shown on the same row
The "end" value of a Situation stage is now a scriptable value instead of just an int. It's evaluated when the situation is spawned, and then stays at that value for the duration of the situation
Added Planet as a possible scope for the `has_deficit` trigger
Added the "damage_army" effect
You can now restrict civics and origins by graphical cultures by using the "graphical_culture = { <restriction> }" restriction in possible or potential. It works like every other civics/origins restriction.
Added "add_random_species_trait" to modify_species, which takes a trigger that's applied to all the possible species traits, and randomly adds one that fulfills the trigger.
Added definition for invisible extra large turret
Added a country_uses_bio_ships scripted trigger
Technology Swap can now change the Area and Categories of the tech. For example, Corvettes (engineering, voidcraft), can become Brawlers (Society, Biology).
Added a ruined_icon parameter to planet buildings allowing them to produce a different icon when destroyed
Added planet_building_capacity_add, allowing planets to function like starbases producing multiple things at the same time
Static Modifier Custom Tooltips can now have parts of their localization designated to be multiplied when a static modifier is applied. This allows for modifiers such as defensive_stations_tracking_add to be defined entirely in script
Origins can now be given a room and city_graphical_culture argument to automatically change the players designs when the origin is selected. The AI should respect this too.
The resources that appear in the top bar are now scriptable and conditional. See how Wilderness handles the Consumer Goods/Biomass swap as an example

We hope you will enjoy these changes even if they happen to thwart your well-conceived exploits. Do let us know if you devise new ones.
Thank you,

*Update*
We have created one more build for you today, same as above but also including an increased save game file transfer speed for your multiplayer convenience.
This build is available as an open beta branch called "stellaris_test".

To opt into this Stellaris Open Beta:
Go to your Steam library, right click on Stellaris -> Properties -> Betas -> select "stellaris_test" branch in the Beta Participation dropdown.

Could a dev confirm please if either a bug or design choice with 4.0 that we can no longer get tileblockers removed during the colonisation process? The management tab is grayed out preventing the player to do so.

Guthuk Gaming · May 27, 2025

Do we have the faster file transfer for desyncs/hotjoins in this version? It's extremely nice and makes MP games take 4-5 hours instead of 8-12 when things get dicey. Very important change. Very good one.

Also will leaders gets fixed anytime soon? Or its intended?

Wait. You could remove tile blockers during colonization? I never knew that.

Yagami913 · May 27, 2025

Maintenance drones on Lathe still not working. I write this every time to every patchnote until get fixed.

Colony Auto-designation now better takes Urban districts into account for flipping to the various Urban-related designations. (We still recommend picking the one you want though. This was mostly intended for the AI)

TBH, the only really weird one I've seen is a propensity for setting fortress world if I had a fortress-building district, even when not at war. (TBH, I don't think fortress world is super useful except when literally under bombardment.) Almost all my planets are still on auto-select, but also they seem to have historically all been tech-worlds (which really isn't inaccurate if you look at the specializations!)

What is the logic to how these things are selected? My intuition is that I expect them to pick to maximize net output according to some generalized output value function, but that could be wildly off-base. (It might also be more expensive to check all the options than I expect, sort of like how pop re-jobbing was actually a bit of a performance hog.)

Incidentally, but not completely related, could we sometime get an explainer on what things each type of automation does? I've been surprised a few times by urban district specializations being built by it, and I want to know when I should expect what behaviors, because planetary automation had actually gotten quite reliable by the end of 3.x!

Invaderxan · May 27, 2025

Good stuff, Is there a patch for telepaths overwriting enforcers and giving absurd buffs on the way, or is that intended behavior?

Zaacplot300 · May 27, 2025

Looks like a solid update, but is there any word on the status of addressing performance? The game is not very playable past the first few decades, at least for me.

Elia_Valkyr · May 27, 2025

Nice set of fixes, is there an ETA about when the auto-mod traits will work like in 3.14? Currently you can't stack multiple of them, and also they become less effective in a pop group that is split between multiple jobs.

Pelagius Fronimos · May 27, 2025

Thank you for your hard work!But I have a question about desync - I'm not very good at interpreting labels in error correction, so I want to clarify if things are better with this now?

Sweeze · May 27, 2025

If the official position of the dev team is that the AI needs to start with bonuses from year 1 to be competent then this would be a good time to implement an option where the scaling starts at a specified lower difficulty and scales to a higher one rather than being forced to scale starting from no bonuses.

Red Death · May 27, 2025

For balance, you might really want to look into how the logistic pop growth cap works (and whether it is even necessary). Right now it seems like the cap is per species, thus meaning that multi-species planets can grow faster by circumventing the cap. This is especially apparent if you take xeno-compatibility.

Drullo321 · May 27, 2025

Will be there be any intention of rebalancing the strategic ressources synthetisation/production buildings? One of the on a midsize planet produce hundreds of them, that even if you are wasteful with them, are enough for your whole empire and to throw it randomly in thousands at AI empires (for fun or trade).

Any other source of strategic ressources is completely obsolete and doesn't even get to 1/100 of what one of those buildings can produce. And if you have the ancient refinery, you even save two more building slots without costing any additional pop to work on.

This isn't just a MP thing, it sucks fun out of singleplayer too as it
a) makes things way to easy (even if you don't use those ressources for war, you can simply get every tradeable ressource other then alloy en masse from AI empires in change for those strategic ressources)
b) you can't simply not use it because the other sources (besides way too late Modularium relic) aren't enough to fuel your empire.

MadCow94 · May 27, 2025

Is purge speed/purge efficiency on the horizon? Right now it's great if you're a purifier (10k pops? Gimme a month or two.) Not so great if you're trying to necrophage or process.

Yes this is intentional, you must have a colony on the planet before you can remove blockers.

Hopefully, I was talking with a programmer today about it.

Yep, that was fixed in this patch.

Yes, this was our "Fix the exploits" balance patch. We still want to do an actual economy balance patch soon-ish. Probably not next week as this week is only 3 days.

fourteenfour · May 27, 2025

Well, we are up to 391 entries under the category of bug fix with this patch.

I want to ask for an economic pass to simply the system and at the same time a pass through the technology trees to do the same but at this point I have to ask, when will 4.x be stable?

Feel free to count them yourselves if you don't believe me, I simply did a cut/paste into Notepad on my Mac and was stunned by the line count

BenDuke · May 27, 2025

Does the Framerate still tank when opening the Planet View or Empire Council?

fourteenfour · May 27, 2025

Being able to use trade modules for Gestalt and Solar Arrays for everyone is a change which makes so much sense. From a head cannon perspective, I roleplay too many of my empires, I like the idea of energy producing starbases.

Voidian · May 27, 2025

Is purging still giving it's effects for a single tick and then deleting the remaining pops for no reason?
