Official announcements, newest first. Posted on Steam.
- 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...

- Community AnnouncementsUpdate 7Last month I laid out a plan for May. Unfortunately not everything on the list made it in. But I did get a good amount done, and I would rather release what is ready than hold it back. This update is mostly about visuals and performance. It also includes a rework of the propeller breakage system based on your feedback. Terrain spawning I spend most of my time reworking the terrain generation sy...
- Community AnnouncementsSmall patchRebalanced engine efficiency curves Rebalanced some wheels Small performance improvement
- Community AnnouncementsUpdate 6This update is focused on physics improvements. The goal was to add more depth without sacrificing the accessibility that makes Aviassembly what it is. I hope this update strikes a good balance. Engine efficiency Engines now have an airspeed-efficiency curve. This means each engine has an optimal speed where it performs best. This is displayed as a new “optimal speed” stat on each engine. I’m h...
- Community AnnouncementsThe future of AviassemblyIt's been a year this month since the early access release of Aviassembly. Development has been a bit inconsistent, so I want to bring some more structure to it and start pushing towards the full release. I'll be doing monthly updates from now on, with the full release planned for August this year. In this post, I'll lay out the future of Aviassembly in a bit more detail. The updates will prima...

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.
