Lightroom 4.2 still shows ACR 7.1

I just updated my Lightroom 4.1 to 4.2 on my Macbook Pro (Snow Leopard). The LR's "about screen" shows LR 4.2 and ACR 7.2 version numbers. But when I go to "Menu->Configure->File Handling" DNG section it shows "camera raw 7.1 and later". I was expecting to see "camera raw 7.2" but could not find it anywhere. I also tried to convert a NEF file to DNG and the same thing -- no way to choose ACR-7.2, only "camera raw 7.1 and later". Is it normal?
