This program does not distribute an official ChangeLog file. You can generate one from the subversion repository though using the following command: svn log http://svn.sleuthkit.org/repos/sleuthkit/ For a specific release, try something like: svn log http://svn.sleuthkit.org/repos/sleuthkit/tags/sleuthkit-3.0.0 and replace 3.0.0 with the version you are interested in.
