Expansions, national focus-tree overhauls, and the dev diaries mapping the next patch.

Generals! Christmas is coming a little early this year in the shape of a large War Effort update. Once again we have put emphasis on adding various QoL features we feel improve the Hearts of Iron IV experience. This has been an effort to address some of the outstanding requests…
Hearts of Iron IV is a trademark of Paradox Interactive AB.
Patch 1.19.4 adds automation for resource trading and diplomatic responses, a repair priority queue and volunteer recall, and folds in the Summer Edition open beta's tank, doctrine and faction-rule balance changes.
For your guild
House rules written around faction-rule penalties need a reread, since the costs halved. Expect tank templates to shift and SAM-heavy air defence to matter; give players a week on the new checksum before a competitive game starts.
Paradox sketched Industrial Parks, a building tied to a corporation and to the state it sits in, producing only equipment matching its profile and drawing bonuses from local resources. The follow-up answers feedback on the earlier military production diary.
For your guild
Nothing to plan around. No patch, no date, placeholder art, and the diary says twice that names, systems and balance will change. It matters as direction only: factory placement would become a decision rather than a pool.
Three modders working with Paradox showed early focus trees for a future Romania DLC. Romania starts friendly with France and Poland, and focuses that shift its partners unlock decisions built on the International Cooperation mechanic.
For your guild
International Cooperation is meant to be shared across every political branch, so read that part if your group plays multiplayer campaigns. Paradox says nothing is finalised and is collecting feedback now, including on its upkeep cost.
The Guild Post gathers the latest Hearts of Iron IV news from Paradox and the wider community into one page — patch notes, updates, and announcements as they publish, each linking back to the original source. Expansions, national focus-tree overhauls, and the dev diaries mapping the next patch.
