When did "UtahRaptors" start jumping?

[phaT-X]

At first I thought it was a glitch, a "UtahRaptor" came running down the hill after me and it appeared as it had jumped at me, I thought it merely went over some uneven ground or a rock or something and blew it away with my shotgun, then another came running down the hill, I fired and missed as it was not running in a straight line, then all of a sudden it "jumped just like the VelociRaptors" do, but with the "UtahRaptor" it's fatal if it hits you! I fell over dead... lol?

I do not remember reading about this update, only changes made to the Triceratops?

this is an older update.

Hmmm, I guess I must have never been in a position for one to do this then, first time it happened was this past Saturday (05-02-15)
