pl6 has been released early this a.m. . Fresh IP2Country db dumbs have also been released. You can find both HERE, both come in full packages and upgrade packages. See CHANGES.txt in the package for details.
Please redownload the upgrade pack if you downloaded prior 20:30 15 May 2006. I missed a line of code in the nsnst.php file and have placed the corrected copy on site.
