Hearts of Iron IV Dev Tracker

A lil somethin somethin: You can find the details for this event on the announcement page here.

An early look at our Patch Notes are available on our forums. Unfortunately, the notes are too large to fit onto steam in this format, an official patch notes post will accompany the release next week.

I will also take this opportunity to point out that as is normal for large updates, saved games from earlier versions will not be compatible with No Step Back. An opt-in rollback to the current live version will be provided when No Step Back and the Barbarossa update launch

Hello everyone!

Patch 1.10.3 of the "Collie" update is now live and should be downloading through Steam and Microsoft Store as we speak. The new checksum is aa89.

This update aims to address a compatibility issue with the recent release of macOS 11.0 "Big Sur".

Saves made with 1.10.0, 1.10.1 and 1.10.2 are expected to be fully compatible with 1.10.3 and you can continue your previous game without risk.

Should you still have an older saved game (from 1.9 "Husky" or 1.8 "Fork"), it will not be compatible with 1.10.3, even if the game does not report it as such. This is sadly an issue we could not fix in this patch without painful side effects (see the known issues[forum.paradoxplaza.com] page).

As always, if you have an older save you can... Read more

This update brings a number of bug fixes and balance changes to the 1.10.1 release of last month (see changelog below for details).

Hello everyone!

Release 1.10.1 "Collie" is now live with its new features and bugfixes. The patch should be downloading through Steam as we speak. The expected checksum is dd56.

If you wonder if you missed patch 1.10.0, don't worry, you didn't! It was only released internally and to our beta testers, but the timetable allowed us to skip ahead and go live with 1.10.1 directly which includes a few fixes for issues found during beta.

Please note that 1.10 will not be save game compatible with 1.9.3. If you want to finish off any ongoing ironman games, please remain on 1.9.3 for now. Here are instructions on how you revert patch levels[forum.paradoxplaza.com].

As always please make sure that any mods you are using are updated for 1.10, or... Read more

We should be compatible with 1.9.2, but if you for some reason want to remain on 1.9.2 or older Here are instructions for reverting to patches since 1.5.4[forum.paradoxplaza.com], or special instructions for 1.5.3 and earlier.[forum.paradoxplaza.com]

Hi everyone! This week is Hearts of Iron IVs 4th anniversary. I’ve got some cool data to share with you, new armor and radio packs as well as patch for you to celebrate! All of this releases tomorrow :)

A Look Back & Cool Numbers

It's crazy how Hearts of Iron keeps growing. I personally started with playing HOI2, and worked on HOI3 as a coder and game director on HOI4, and while people still call it a niche experience for WW2 buffs, it has also grown to be so much more (or us WW2 nerds are more numerous than we think :D). Around La Résistance release we clocked a new record on monthly players of 899k (the 1... Read more
