On the download page you'll see "UFO:AI binaries" and "UFO:AI installer". The first only gives you new executables and accounts for changes in the source code. The installer gives you all new artwork, so map fixes, script fixes, etc will only show up in the installer.
You can attach files to a feature request or bug on SF. You should do that with the ufoconsole.log, although include a small relevant snippit in the comment is nice as well. If you need to attach more than 1 file, you can do so with multiple comments (as geever mentioned, SF's bug tracker is not exactly user-friendly).
