   o Major features (security, unix domain sockets):
-    - Tor can now expose a SOCKS proxy over an AF_UNIX Unix Domain
-      Socket. This allows client applications to Tor without having
-      creating AF_INET or AF_INET6 sockets. If an application has
-      permission to connect to Tor's AF_UNIX socket, it can communicate
-      with Tor as if it were an other SOCKS proxy. This should allow
-      high risk applications to use Tor while completely disabling their
-      ability to make non-Tor connections. To create a socket of this
-      type, use "SocksPort unix:/path/to/socket". Closes ticket 12585.
