Question: A lot of torrent search engines have the ability to provide an RSS feed of matches, allowing you to set up torrent programs to download items which are published on the feed. This is useful for watching releases of things.

The problem with doing this through a random search engine for Ubuntu is that you usually get too many torrents as it picks up different custom versions, and other software with the name in the title/description. See: <http://www.mininova.org/rss/ubuntu> 

So I was wondering if there was an RSS feed somewhere that only loads up the official torrent files for releases?

So from the responses, there doesn't appear to be an existing RSS feed that does what I am after.

Answer: 
I don't know if that helps but you could use the [metalink](https://wiki.ubuntu.com/metalink) file which can be found here: [Daily- builds](http://cdimage.ubuntu.com/daily-live/current/)

as you can see in this file there is a link in `./files/file/resource/url` wich points to the latest torrent.
If you bookmark the Ubuntu.com ( <http://cdimage.ubuntu.com/daily-live/current/>) you will see it in seconds. This is what I do with google chromes bookmark and the 24 links ( you will have to drag from page to page. ) on the page. instant access. Or you can get a igoogle page from your gmail account. I hope this is helpful to you.
