This plugin creates a custom news feed that can be read by the <a href="https://wordpress.org/plugins/dashboard-custom-feed/" rel="ugc"><code>Dashboard Custom Feed</code></a> plugin. News items are added through a custom post type called DCF Updates
This is mainly useful for notifying all your clients of something through their wordpress dashboard, whether that be a link to a new blog you’ve written or a notification asking everyone to upgrade their versions of wordpress. It’s really up to you what you show in there.

Dashboard Custom Feed Admin

Creates a custom post type to power a custom news feed

elebail

Creates 4 feeds :
trdf => rdf in theme (template : feed-rdf.php)
trss => rss 1.0 in theme (template : feed-rss.php)
trss2 => rss 2.0 in theme (template : feed-rss2-comments.php and feed-rss2.php)
tatom => atom in theme (template : feed-atom-comments.php and feed-atom.php)
Those feeds look for a feed template into the theme directory. 
If no template is found into the theme directory the feed uses the default wordpress feed template.
This plugin has been tested with WP2.6.5, WP2.8.4 and WPmu2.8.4
