RouterOS 7.15beta8 came with this change:
*) wifi - show inherited properties with "print" command (replaces "actual-configuration") and added "print config" for showing only configured values;
While the old code is bad syntax with RouterOS 7.15, the new code is
valid for older RouterOS, but produces different (and more or less
unexpected) results. 🥴
Let's use the new code, and add a check on the RouterOS version.
With old RouterOS this now sends the notification even if the interface
is disabled.
