The last month of the past year was crazy for many, and the developers at SCS Software were no exception. They released a large number of updates and expansions for their projects but did not manage to release the American Truck Simulator 1.30 update, which was ready a couple of days before the holidays and vacations. Releasing this update at the end of December would have been quite risky because if a serious bug had been discovered, it would have been very difficult to fix it. Therefore, a decisive decision was made – to wait until the end of the holidays and vacations, and then release version 1.30 for American Truck Simulator.

This update mainly consists of fixing some bugs as well as improving the game's compatibility with various mods.

If your copy of the game is activated on Steam, it will update to the latest version automatically unless you have disabled this in the settings or forced support for one of the previous versions to maintain compatibility with mods that do not update. In any case, the ATS 1.30 update is already available on Steam.

List of changes:
- Added support for simulation of new engine types;
- Fixed terrain rendering when approaching unloaded sectors;
- Traffic will no longer use turn signals in cases where they failed to change lanes and no lane change occurred;
- Fixed triggers in some rest areas that did not appear in the interface after loading the game;
- Improved weight distribution calculation for semi-trailers with liftable axles;
- Various improvements and fixes to the editor (marks in the content browser, support for hidden geometry, collections, tool parameter information, search, traffic tools);
- Cleanup of OpenGL support;
- Fixed light source rendering at different times in HQ screenshots;
- Fixed bugs that could cause crashes when using roads without materials;
- Fixed bugs that caused crashes when attempting to create a new nameplate template in the cabin in custom mods;
- Updated localizations.
