@@ -110,7 +110,7 @@ Creating a new client takes a hash of options. For valid iconv encoding options,
 * :appname - Short string seen in SQL Servers process/activity window.
 * :tds_version - TDS version. Defaults to "7.3".
 * :login_timeout - Seconds to wait for login. Default to 60 seconds.
-* :timeout - Seconds to wait for a response to a SQL command. Default 5 seconds. Prior to 1.0rc5, FreeTDS was unable to set the timeout on a per-client basis, permitting only a global timeout value. This means that if you're using an older version, the timeout values for all clients will be overwritten each time you instantiate a new `TinyTds::Client` object. If you are using 1.0rc5 or later, all clients will have an independent timeout setting as you'd expect. Timeouts caused by network failure will raise a timeout error 1 second after the configured timeout limit is hit.

 * :azure - Pass true to signal that you are connecting to azure.
 * :contained - Pass true to signal that you are connecting with a contained database user.
