Faction and Aggro

What version of Eqemu was this implemented?

I ran a test by truncating my npc and faction databases completely. I created two factions called the Hatfields and McCoys. One faction was a dark elf hater and the other was a dwarf hater. I set a dwarf and dark elf on the same waypoint patrol, each assigned to their corresponding faction. The dwarf and dark elf had identical stats apart from race. They passed each other on their patrols without conflict.

However, I could create a character with identical stats and change my race to one or the other, and they would attack me accordingly.
