Avē!

My name is Erik Jakobsson, but most of you know me as Katten. I work as a Community Manager for Hearts of Iron IV & Millennia, and with great joy, I can finally tell you that it’s here—Patch 2.0.4 Augustus is now available for everyone on Steam, GOG, Microsoft Store, and GeForce Now! This patch contains 158 bug fixes, improved performance, 25 new modding tools, as well as the ability to earn achievements while playing mods. Now, before we jump into the patch notes, I want to share how this patch came to be!

A look back Last year, Niels Uiterwijk, currently the Technical Director at Studio Green and the former tech lead for Imperator, decided to begin work on a small maintenance patch for the game. This patch aimed to address issues encountered by modders and regular players. It entered Open Beta exactly one year ago, on April 25th, 2023. However, it remained dormant and was not released to the live branch due to the requirement of needing to release simultaneously on all platforms. This posed a technical resource demand, and simply put, there wasn’t enough time available, as Niels was working on this project in his spare time.

The Imperator Day As we entered 2024, we began hearing whispers of creators coming together to revive Imperator in some capacity. This event was set to take place on February 17th, 2024. We decided to lend our support to this fan-driven initiative by making a small announcement on our Imperator social media channels. When the event took place, it surpassed our expectations, doubling the peak concurrent player count.

Following the success of the event, we learned of Imperator Day 2.0, once again organised by Laith from Socialstreamers. This time, we decided to take more proactive steps and announced an Ides of March Sale for Imperator, while also showcasing the exceptional mod, Imperator: Invictus. The event saw another doubling of player numbers, reaching a peak of 2708 players, a figure not seen since early 2021.

This surge in community engagement prompted several former Imperator developers—such as Johan Andersson, Peter Nicholson, Evan Wu, and once again Niels—along with other developers like Lorenzo Berni and Erik Nikko who are passionate fans of the game and wanted to contribute, to begin work on the 2.0.4 patch as a gesture of appreciation to the Imperator community.

Collaboration with Modders In the early stages of this patch’s development, Niels integrated a mod called the Unofficial Patch Mod, created by “Umgssda.” During the early days of Imperator, I engaged in discussions with the Invictus mod team and other creators to compile a list of Imperator: Rome Modding requests. The aim was to provide modders with the necessary resources to create their dream mods.

With the Modding Request list in hand, multiple developers dedicated spare time and personal development time (PDT) but Studio Green, Gold and Tinto all provided dev time to contribute to the development of the 2.0.4 patch. Updates for the patch began to roll out. It was during this phase that I once again reached out to Invictus regarding their vanilla bug fixes. They graciously agreed to grant us access to incorporate these fixes into the base game, further enhancing its stability

The Release As we celebrate the release of 2.0.4 Augustus, I will provide a comprehensive credits list below, acknowledging everyone who contributed to this patch. Their names are now included in the game credits.This patch is a labour of love from the original developers of the game, along with others like myself, who simply adore Imperator and wish to give back to the community.

I also want to specifically note the amount of effort that Lorenzo Berni (@Duplo) has put into this, it is a huge undertaking into reviving old pipelines to make builds for all platforms & stores.

Thank you all for being part of the Imperator community and for playing this game. You are all truly amazing <3

Patch Notes #######################

2.0.4 Augustus

######################

Notes

This patch should be save compatible, however not all fixes might be applied to your current save.

Stability & Performance

Improved overall memory consumption & performance
Improved monthly tick performance by performing some more calculations in parallel (state modifiers)
Portrait editor no longer crashes on open
Updated SDL to 2.0.20 from 2.0.10
Updated Nakama to 2.4.1 from 2.2.4

Bugfixes

Fix release as client state crash in the UI
Fixed bug where temp modifiers were removed when provinces are annexed as part of a civil war
Fix a bug when using add_to_war effect, adding a defender would always make it the war leader
Fixed a bug where when annexing a country, their abroad prisoners, that were in your prison, would also be counted as an abroad prisoner for you, even though they are local prisoners.
Fixed levy calculations being inverted
default pop right is now correctly working & added proper logging of pop rights
Fixed bug where unused modifiers were still being rewarded for specific missions (local & global cohort recruitment speed)
Fixed bug where integrated cultures were still treated differently when they were converting to your primary religion
Raised levies will select the best tactic for its composition.
Civil Wars will no longer just pick 1 character, but instead take far more disloyal characters.
Fixed bug where released nations during a peace deal would have no proper pantheon.
Fixed bug where you would never see battle results from battles against pirates, barbarians or rebels.
Fixed bug where pops could be promoted above what they were allowed to.

Game Mechanic

Diplomatic range is now calculated between border territories. This should make it easier to hire mercenaries as a large empire. Default diplo range has been tweaked based on this change.
Added four new defines to balance the game (2 related to combat overruns, 2 related to civil war & dissenters)

Modding Tools

Added a modifier cultural_assimilation_speed_modifier, which changes the assimilation speed. Assimilation speed less than 0 prevents assimilation.
Added a property for subject types to allow them to bypass usual subject diplomatic limitations for declaring war (allowed_to_declare_war_against_others). This is not enabled by default for the base game. To fully enable this to work you’ll also need to change the allow triggers for wargoals
Added play_sound_effect which allows you to play a sound effect, targeting a country (ported from ck3)
Added set_antagonist = yes/no effect.
Added has_capital_surplus to check for the existence of any capital bonuses from the state’s owner
Added has_capital_bonus_for_trade_good to check for the existence of any capital bonuses for the specific trade good
Added a property for subject types to allow them to bypass usual subject diplomatic limitations for declaring war (allowed_to_declare_war_against_others). This is not enabled by default for the base game. To fully enable this to work you’ll also need to change the allow triggers for wargoals
Added modifiers for local_happiness_for_wrong_religion_modifier and happiness_for_wrong_religion_modifier which is applied on top of regular happiness for the same religion modifiers. Also fixed a typo with define for WRONG_RELIGION_HAPPINESS which applies always regardless of modifiers (currently set to )
Made all hardcoded values related to civil wars moddable through define & added documentation on what they mean
Added is_automated_trading trigger to check if a state has automated trading set
Added distance_from trigger to check the distance between a province and another province, state (capital) or country (capital)
Added can_unlock_invention to check if an invention can be unlocked by country (optionally ignoring cost, dependencies and potential trigger)
Added can_add_trade_route to check if a trade route can be added.
Added set_player_country effect to allow modders to switch the player’s country
Added add_deity_to_pantheon effect to allow deities outside of the allowed pool to a country’s pantheon
Added set_automated_trading effect to enable/disable state automated trading
Added set_governor_policy effect to change governor policy
Added unlock_invention effect to directly unlock a invention for free (without checking preconditions)
Added add_trade_route and remove_trade_route effects to add and remove trade routes, respectively
Enabled script profiling (available with -debug_mode startup command, 'print_event_timings` is the console command)
Added option to run multiple commands at the same time (ExecuteConsoleCommands & ExecuteConsoleCommandsForced)
Achievements now only require that the game is in ironman mode and you achieve them within the time limit (in-game years) Note: This means that mods that are affecting the checksums, no longer will prohibit you from getting the achievements, neither does multiplayer.
Upped the maximum number of tags (countries) from 2048 to 8192
