Just to let ya know.. I did a beyond compare and the files from and the ubbthreads-6-4-all-langs.tar.gz I downloaded on December 5th and the ubbthreads-6-4-all-langs.tar.gz I downloaded on December 8th are different... Not only is the addpost.php changed to reflect the change scream said above but they fixed the altertable.. also in the one I downloaded on the 5th there was two files one called oc_login.php and one called temp.php also in the addpost.php there was a line stripping the icons url but in the Dec 8th that is now gone..
the ubbthreads-6-4-english.tar.gz I downloaded on the 8th is the same as the ubbthreads-6-4-all-langs.tar.gz I downloaded on the 8th Minus the langauge files and it also differes from the ubbthreads-6-4-all-langs.tar.gz I downloaded on the 5th..
the one on the 5th did NOT have this line if ($addpoll && $questions) {
so in 3 days they altered the file this much...
