Pathing or movement change?

Has something changed since the last-ish patch with pathing and movement? Or maybe with minion hitboxes? I'm not sure exactly what it is, but I find myself getting locked into AA animations when navigating minions waves while kiting, which isn't something I have ever had to deal with before. I've been playing Urgot and Satan more recently, and it's pronounced on both of them, whereas I don't notice it as much on, say, Darius.
