LAUNCHXL-CC2650: Need latest user guide for BLE stack of CC2650

Hello,

I am developing product with lauchxl-cc2650.

I have come across

 https://software-dl.ti.com/lprf/sdg-latest/html/ble-stack-3.x-guide/index.html

this user guide.

Its heading is "BLE-Stack User's Guide for Bluetooth 4.2"

Inside this its desclaimer says its for CC2640r2f.

I liked the way everything is explained in this user guide.

My question is should I use this in my product development, in which I am using CC2650 or there is some other user guide for CC2650?

Please enlighten me with your help
