         . Options passed to mysqldump are now customizable with the new
           sqldumpoptions configuration variable. Thanks to Chris Lamb for his
           preliminary patch (Closes: #502966)
+        . Hide 'mysqladmin ping' output, to prevent confusing the user in
+          case mysqld is running but the authentication fails, which apparently
+          does not prevent mysqldump to work.
+        . Fix the error message displayed when mysqld is not running:
+          mysqladmin ping indeed returns 0 when authentication fails.
