Not necessarily, though that is definitly one form a RetCon. RetCon can also simply provide additional information in a part of the story that has yet to be fleshed out. For instance, the story where Rumple met and subsequently killed Fendrake is definitely a Ret Con, but it did not change any existing information, it simply added to what we already knew.

However, I digress, and further discussion of this sort needs to be taken to a different thread.
