Version 7 is out! This version is a big update, random variants for every spawnable vehicle have been added, so you're guaranteed to see much more diverse traffic on the streets. Keep your eyes peeled for some really bizarre looking cars as well! This version also brings some very small changes to gang grunts' weaponry and melee strength, and enables undercover cop cars to spawn alongside regular ones on the street. Female cops also spawn much more commonly, too.
EDIT: Uploaded V8 a little later to make a small change to the law cap.
