 ### Changes
+- Allow more interfaces to be used for multicast routing, in particular
+  on Linux, where interfaces without an IP address can now be used!
+  Making it possible to run SMCRoute on DHCP/PPP interaces, issue #13
+- Add support for TTL scoping on interfaces, very useful for filtering
+  multicast without a firewall: `phyint IFNAME ttl-threshold TTL`
+- On Linux a socket filter now filters out ALL traffic on the helper
+  sockets where SMCRoute does IGMP/MLD join/leave on multicast groups.
+  This should eliminate the extra overhad required to, not only route
+  streams, but also send a copy of each packet to SMCRoute.
+- Add support for limiting the amount of multicast interfaces (VIFs)
+  SMCRoute creates at startup.  Two options are now available, by
+  default all multicast capable interfaces are given a VIF and the user
+  can selectively disable them one by one.  However, if the `-N` command
+  line option is given SMCRoute does *not* enable any VIFs by default,
+  the user must then selectively enable interface one by one.  The
+  syntax in the config file is:
+
+        phyint IFNAME <enable|disable>
+
+  Use `enable` per interface with `-N` option, or `disable` by default.

 - Make build ID optional.  SMCRoute has always had the build date
