Changes in physics, reflecting a more nuanced understanding of the physics engine
- adjusted inertia
- adjusted mass for struts
- adjusted tire curves
Plus...
- put data into an acd for online use convenience
- removed textures from LOD which didn't need them for smaller zipfile
Essentially just a year of changes too minor to individually mandate an update. Tire curves are the only one likely to influence handling, the rest is just right for the sake of being right.
