Official announcements, newest first. Posted on Steam.
- Community AnnouncementsUpdate 11This update is focused entirely on controller support. A lot of people experienced issues with it, so I felt it was necessary to address it. Added HOTAS / Joystick support A much requested feature has been HOTAS support. I didn’t own a joystick, but recently bought one and implemented support for it. When you connect your joystick, you might need to do some setup first in the keybindings screen...
- Community AnnouncementsUpdate 10Cloud Saves I added Steam cloud saves to the game, which was a highly requested feature. This means that save files should now be automatically synced between multiple devices. Rotation joint changes I added some features to the rotation joints that should make them a lot more useful. You can now clamp the minimum and maximum angle, set the speed it rotates at, and toggle whether it returns to...
- Community AnnouncementsUpdate 9Endless quests The most common feedback I’ve received is that players are disappointed that there are no new quests after finishing the game. A common suggestion has been to add endless randomly generated quests for those who want to keep playing. Implementing this turned out to be quite a challenge. While quests are simple conceptually, just a cargo type and an amount that needs to be delivere...
- Community AnnouncementsUpdate on the full releaseI want to give a quick update on my progress towards the full release. The roadmap I posted in April is proving to be a bit too ambitious. The first 2 months went well, and while I did manage to ship Steam workshop support, some of the promised features of June were already delayed. I’m currently still working on endless mode, which will hopefully ship this month. However, the game will unfortu...
- Community AnnouncementsUpdate 8I had a lot more planned for this month than I actually got done. The same thing happened last month, so my planning has been a little optimistic. But it’s not all bad, I did add a big feature this month. Steam Workshop This month finally brings the Steam Workshop to the game. You can now upload your planes for others to try, and browse what other people have made. I’m hoping that being able to...

Why Aviassembly mods break
A mod is compiled against one version of a game. When the game updates, anything that reached into the parts that moved stops working, and it usually stops working silently rather than with a message that explains itself.
That is what the table above counts. It is not a guess: each row is a mod the community has reported as broken by that specific release. The number is a fair measure of how disruptive an update was, and it is the reason people delay updating a game they have modded heavily.
Common questions
Does IndexGG host Aviassembly mods?
No, and it never will. Every download link points at the author's own page on Nexus, GitHub, CurseForge or wherever they published it. We index the ecosystem; the files stay with the people who made them.
Where does the compatibility data come from?
From the communities that maintain it in the open, not from guesswork. Each claim carries how it is known, so a reported breakage is never presented as though the author said it.
Why is a mod listed as broken when it works for me?
Compatibility depends on your exact game version and the rest of your load order. A mod marked as broken in one release may work fine on an older one, which is exactly why the version is recorded next to the claim rather than a bare yes or no.
