RSS web feeds deliver information and content in such a way that allows one to track updates using an aggregator. µTorrent can aggregate and parse an RSS feed, allowing one to automatically download newly released .torrent files that match a specified filter. Such feeds must give direct links to the .torrent files in at least one of either the <guid>, <link>, or <enclosure> tags in order to be used correctly. To access the RSS Downloader, select "Options" then "RSS..." in the main menus, or press Ctrl+R on the keyboard.
