Have the IV values of my 'mon porfolio been affected by the change?

I haven't read anything that confirms there is no change, just making sure. I have tested a few of my 'mon with the IV calculator today and they appear to be the same.

My understanding is that only the base stats have changed and that the IV have remained the same.

Side note, I had four awesome 'mons in my 'dex that rounded out my collection but weren't being used; high IV Rhydon & Gengar & Jolteon & Aerodactyl. I was pleased to see them become so relevant so quickly. I don't have an Arcanine so I was pleased to avoid the disappointment of that nerf.
