Of course, I'm not a Subversion developer so I've used an external tool for that. As it is 100% free tool I think there is not problem announcing it at this mailing list. Screenshot: http://www.svnflash.com/components/com_ccboard/assets/uploads/62_9fa26b27449d15c07a49fc884484b5d1.jpg At the web site (http://www.svnflash.com), there is also a Live Demo publishing the Apache's Subversion repository at real time, so everybody can see how it works. For example, you can compare the future 1.7 release (trunk?) with the latest 1.6.15 release (tag) of the Subversion project and get the revisions for any changed path.
