There's also going to be some general tweaks to some of the alternate recipes that are new to Update 4.

But again, it's mostly related to ratios and how many per minute you may need to feed to get full efficiency.

So don't worry about ingredients or anything like that.

If you are one of those people that are like, oh, I don't want to start setting up a production line if I have to make any changes whatsoever, then stay away from the alternate recipes because those are the ones that are most prone for change.
