[Fluxx] Dead Friends Question

[lisa]

I remember when playing at Gen Con, Andy had changed the wording on Dead
Friends so that friends only changed to creepers after they were played, not
if they were in your hand & that they were changed to Zombies, not staying
friends... neither of those changes are on the final card, though. Andy -
did you change your mind?

With the current wording, how do you kill a friend creeper? Does it stop you
from winning? Is it still a friend? Can it help you with a goal that
requires a friend?
What is the actual effect of it?
