Does anyone know which lines to modify in 2.0?

Here are the functions:

// ###################### Start delete thread #######################
function deletethread($threadid,$countposts=1) {
  global $DB_site;

  // decrement users post counts
  if ($threadinfo=getthreadinfo($threadid)) {
    $postids="";
    $attachmentids="";

    $posts=$DB_site->query("SELECT userid,attachmentid,postid FROM post WHERE threadid='$threadid'");
    while ($post=$DB_site->fetch_array($posts)) {
      if ($countposts) {
        if (!isset($userpostcount["$post[userid]"])) {
          $userpostcount["$post[userid]"] = -1;
        } else {
          $userpostcount["$post[userid]"]--;
        }
      }
      $postids.=$post['postid'].",";
      $attachmentids.=$post['attachmentid'].",";
    }

    if (is_array($userpostcount)) {
      while(list($postuserid,$subtract)=each($userpostcount)) {
        $DB_site->query("UPDATE user SET posts=posts$subtract WHERE userid='$postuserid'");
      }
    }

    if ($attachmentids!="") {
      $DB_site->query("DELETE FROM attachment WHERE attachmentid IN ($attachmentids"."0)");
    }
    if ($postids!="") {
      $DB_site->query("DELETE FROM searchindex WHERE postid IN ($postids"."0)");
      $DB_site->query("DELETE FROM post WHERE postid IN ($postids"."0)");
    }
    if ($threadinfo['pollid']!=0) {
      $DB_site->query("DELETE FROM poll WHERE pollid='$threadinfo[pollid]'");
      $DB_site->query("DELETE FROM pollvote WHERE pollid='$threadinfo[pollid]'");
    }
    $DB_site->query("DELETE FROM thread WHERE threadid='$threadid'");
    $DB_site->query("DELETE FROM thread WHERE open=10 AND pollid='$threadid'"); // delete redirects
    $DB_site->query("DELETE FROM threadrate WHERE threadid='$threadid'");
    $DB_site->query("DELETE FROM subscribethread WHERE threadid='$threadid'");
  }
}

// ###################### Start delete post #######################
function deletepost($postid,$countposts=1,$threadid=0) {
  global $DB_site;

  // decrement user post count
  if ($postinfo=getpostinfo($postid)) {
    if ($countposts) {
      $DB_site->query("UPDATE user SET posts=posts-1 WHERE userid='$postinfo[userid]'");
    }
    if ($postinfo['attachmentid']) {
      $DB_site->query("DELETE FROM attachment WHERE attachmentid=$postinfo[attachmentid]");
      $DB_site->query("UPDATE thread SET attach = attach - 1 WHERE threadid = '$threadid'");
    }

    $DB_site->query("DELETE FROM searchindex WHERE postid=$postid");
    $DB_site->query("DELETE FROM post WHERE postid='$postid'");
  }
}

Thanks in advance
