Wall contact incidents are now either 0x or 2x, instead of 3x. Also, the polar moment of the car is considered as well when determining the impact strength, which does a better job of evening out the contact incident points across different cars. It is easier to get a 2x in the Legends, for example, and harder in the Late Model or Silverado.
The pit speed limit is no longer applied if pace field begins an oval race’s parade laps from within the pit lane.
Improved processing of cars involved in causing cautions to reduce problems if they are lapped before resuming pacing speeds.
Some small changes have been made to the telemetry API.
