This was released earlier in the week. I installed it on my FortiWifi 60C and it caused my firewall to no longer respond to ARP requests, thus making it invisible to my network. Rolling back to 4.0 MR2 Patch 8 fixed the problem. I then re-installed MR3 Patch 2 via tftp as a clean install and had the same problem as before with no ARP responses.
Let me know what you find on other platforms.
