Patches for PHP-Nuke 6.6 through 8.1 have been updated to version 3.5, basically the patches underwent cleanup for removal of redundant code, some fixes were applied including one for a very old Downloads and Web Links modules bug that affects the average user votes graphic chart displayed when a download or link is edited in the admin section. The rest are minor bug fixes.
The patch for PHP-Nuke 6.5 should also be launched once it has been tested, the one for 6.0 has been dropped. Download locations as usual can be found in the top section of the front page of this website. Several new bug fixes were applied to the 6.9 through 7.9 patches as of 3/11/08.
