The download page on the Xarchiver website points to the 0.3.9 beta instead of 0.4 http://xarchiver.xfce.org/download.php Rather than having the extra page to maintain it might be easier to have the download link point directly to the Files section of the Sourceforge project page for Xarchiver http://sourceforge.net/project/showfiles.php?group_id=140153
Fixed. Thanks.
