Version 2.8 has been updated for WordPress and updated a redundant function. Version 2.7.1 includes pagination of links, easier setup of htaccess (permalinks) and allows admins to pass variables to their redirects. It also allows customisation of the permalink so you're no longer limited to /u/23.
Modify u.php if you'd like a custom message when a redirect is not found.
