Since WordPress Version 2.5, WordPress automatically checks if a new update for an installed plugin is available. However, you still have to check your wp-admin to see the notification. This plugin informs you via e-Mail when a new update is available.
It uses the WordPress build-in update function to periodically check for new versions at the WordPress plugin directory. If a new version is available, either a single or multiple administrators will recieve an e-mail, informing them which plugins needs to be updated.
