I just grabbed 2.0.6 the other day and this fix is implemented. I'm
seeing the fix starting at (my) line 80 in file
'includes/functions.php'.
It is placed directly above the following unique instance of code you
should currently have:
"$sql = "SELECT *
FROM " . USERS_TABLE . "
WHERE ";
$sql .= ( ( is_integer($user) ) ? "user_id = $user" : "username = '" .
$user . "'" ) . " AND user_id <> " . ANONYMOUS; "
which should be somewhere around line 60-70 in your current
includes/functions.php file. That is the only instance.
