Track maps are now interactive. Open one from Career or the race screen to zoom in and drag around the course. Tap a numbered section to see its details, and use the arrows to step from one section to the next.
Races start faster after you press Race. On the Nordschleife the wait drops from about 4 seconds to just over 1, and other long tracks start 3 to 5 times faster. The follow camera on the Nordschleife no longer stutters during replays.
If you want to know how the Nordschleife was rebuilt from OpenStreetMap data, there's a new Dev Note about it.
