 # 0.5.1.0
 
+## Configuration changes
+
+Please note that the default listen parameter for production setups got
+changed. diaspora\* will no longer listen on `0.0.0.0:3000` as it will now
+bind to an UNIX socket at `unix:tmp/diaspora.sock`. Please change your local
+`diaspora.yml` if necessary.
+
