To be fair, they now want to create the definitive lore after all this years. So we finally may get a good overview for the rest of the world. But to be honest, besides the elves I and Source can't really remember much that got changed.
But even in Divinity 2, the Patriach mentioned "Creation Magic" or something like that, before it got a big concept. So they retcon some thing, but it is about rewiriting it so much, that it doesn't feel like a retcon. I mean, the Ultima series for example retconned itself also a lot it was praised for it's lore.
And thankfully for Divinity, a lot of lore wasn't very connected, since every game after Beyond Divinity stood on it's own feed.
