Hi,
5.0.4b is another quality beta release thanks, would put some final/commericial software to shame!
The only thing I've spotted that hasn't been mentioned recently is the entire phrase search doesn't quite work. I think someone mentioned it before but maybe not.
Line 676 of /include/db/mysql.php is:
$terms = $search;
but $terms needs to be an array for the foreach a few lines on, so a fix is to make it:
$terms[] = $search;
or
$terms = array($search)
