Description: Android version upgrade issue

My Asus Zenfone 3 is still on its original Marshmallow OS since I need that for my old apps. Now the phone is prompting me to upgrade to Android 7 Nougat but I am afraid that the update might include Android Security Patch Level greater than March 5, 2017 so my question is what is the security patch level included in the firmware version 14.2015.1701.13?
