Several of the Trac modules support content syndication using the RSS (Really Simple Syndication) XML format. Using the RSS subscription feature in Trac, you can easily monitor progress of the project, a set of issues or even changes to a single file .
Trac supports RSS feeds in:
Anywhere in Trac where RSS is available, you should find a small orange XML icon, typically placed at the bottom of the page. Clicking the icon will access the RSS feed for that specific resource.
Note: Different modules provide different data in their RSS feeds. Usually, the syndicated information corresponds to the current view. For example, if you click the RSS link on a report page, the feed will be based on that report. It might be explained by thinking of the RSS feeds as an alternate view of the data currently displayed.
