The upgrade went fine, but after the upgrade both my wired (re0) and wi-fi (wlan0) interfaces were active. I have a static mapping for the wired interface on my router. The wi-fi interface uses DHCP. I could ssh in under either address, but the admin console and polyglot were running under the wi-fi interface's IP. Everything worked, but things were a little confusing with 2 entries in the IoX finder, with both listing the wired interface's UID.
After a reboot just now only the wired interface is active again.
