Recommened PAN-OS as of April 2017 (Q2)

What PAN-OS are people running these days? I am currently 7.0.8 and it is time for the care-and-feeding of the firewall code at my company. I am looking at upgrading to 7.1.8 (but 7.1.9 just came out today). I do not use any SSL Decryption features. Primarily firewalling, IPSEC tunnels and GlobalProtect.

Resolved! NAT Security rule

I'm used to working on Cisco ASA and I'm having a hard time understanding why the security rule states Untrust-L3 for both the source and destination zone. Typically wouldn't that be Untrust-L3 to DMZ? Is there a specific reason for this behavior?
