Problems corrected in 4.0.0 Beta 7.
1) If 'routeback' and 'detectnets' were specified on an interface,
limited broadcasts (to 255.255.255.255) were dropped when forwarded
through the interface. This could cause broadcast-based
applications to fail when running through a bridge with
'detectnets'.

when forwarded through the interface. This could cause broadcast
and multicast based applications to fail when running through a
bridge with 'detectnets'.
2) Entries in the hosts file are now more carefully
validated. Previously, very obvious errors would result in run-time
