If you’re still rolling on the older Patch 1.5.2 and looking to jump to Patch 1.6.1, you’re in for some significant changes. While this isn’t a "major" version jump (like 1.x to 1.4x), the 1.6.1 update introduced several key features, bug fixes, and compatibility shifts that bridge the gap between the early "Scandinavia" era and the pre-1.9 gameplay overhaul.
Important Note: There is no direct incremental patch from 1.5.2 to 1.6.1. You will need to update through Steam (recommended) or apply a cumulative patch if using a retail/disc version.
Moving from 1.5.2, players noticed immediate improvements in the quality-of-life sector. The patch addressed several persistent issues that had affected the simulation feel: Euro Truck Simulator 2 Patch 1.5 2 To 1.6.1
