Update Manager is a new plugin-management-plugin to help keep your WordPress installation up to date.
Update Manager checks the details of your installed plugins against the latest versions listed on WP-Plugins.net (the largest WordPress plugin library). If it finds a newer version is available it alerts you and provides a link to the wp-plugins page for download & instructions.
All feedback, suggestions & grand ideas welcome, on my site or here in the forums.
