+    * ``bzr serve`` now listens on interface 0.0.0.0 by default, making 
it
+      serve out to the local LAN and fixing bug 98918. (Robert Collins)

This is a bit misleading: listening on the wildcard address means we 
will accept connections from anyone in the world who can reach us.

Also everyone but you has been putting it in this format:

   listen on address blah blah (Robert Collins, #98918).

so please do that for both of these.

Maybe the docs should warn that connections will be accepted from anyone 
anywhere?
