-## General Information

 As shown in the images above the new leaderboard seems to have way more traffic than the previous version. The leaderboard 2.0 uses an enhanced version of CARLA 0.9.14. So be aware that even if the documentation mentions this version tag, there are probably features missing.
 Therefore it is recommended to use the latest version.
