 # httr 0.6.1.9000
 
+- `oauth1.0_token` and `oauth2.0_token` now permit the `oauth_listener` to listen on
+  a custom IP address and port (the previously hardwired ip:port of `127.0.0.1:1410`
+  is now just the default).  This permits authentication to work under other settings,
+  such as inside docker containers (which require localhost uses `0.0.0.0` instead).
+  Thanks @cboettig (#211).

 # httr 0.6.1
 
 * Correctly parse headers with multiple `:`, thanks to @mmorgan (#180).
