  * Animals will attempt to flee to safety when a player that previously punched them 
    returns to the field of view.
 
- * Monsters no longer randomly attack but rather exhibit varying degrees of aggression via 
-   a Perlin noise function.
-
  * Creatures avoid running into most obstacles by analyzing the surroundings and steadily

+   adjusting their course.
 
  * Mobs can be randomly spawned in the vicinity of players, thus relieving the overhead of 
    costly ABM-based spawners.
 
  * Timekeeper helper class ensures efficient dispatching of mob-related callbacks at the
-   appropriate server cycle.
-
- * Animals can be programmed to follow players or to grab items that are wielded by or 
-   dropped by nearby players.
+   appropriate server step.
 
  * And of course, much much more!
