UpdateRadar 4.0 is the latest release of the popular version-tracking utility. UpdateRadar keeps track of your programs and notifies you when they need to be updated. It uses the MacUpdate software database to retrieve the new updates. Version 4.0 adds a completely redesigned one-window interface, faster connectivity to MacUpdate’s database, new import and export commands to make backups of your watch list, and a new ‘Top Software’ panel. UpdateRadar is US$12 shareware.
