FishEye delivers a unified view of your source repository that provides easy navigation, powerful search, historical reporting, configurable file annotation and diff views, change-set analysis, RSS feeds, and integration with your issue tracker.
You can easily traverse directory hierarchies, see the latest changes, search based on combinations of author, date, tag, branch, file, and comment, view diffs between arbitrary revisions with configurable context and whitespace exclusion, easily navigate between diff blocks and extended diff view shows actual changes within a line. Moreover, RSS Feeds keep you in touch with the action from any point in the repository.

One observation from
a GlassFish developer.
"Go to http://fisheye.cenqua.com/java.net/viewrep/cvs, click on the "Feeds" link in the upper right corner and you'll get the RSS feeds for the checkins made in recent past! This, combined with the good browser like Firefox makes me subscribe to "live bookmarks" makes me not look for the e-mails for checkin logs."
