System Response

You can continue to use the old logs. However, the old logs serve only
for showing old log entries that are not available in the new log. For
the new logs, however, we recommend that you use the new log
transactions because not all actions can be performed in the old log
transactions or not all information is up-to-date. In particular:
The <LS>Reverse </>function for top-down distribution can only be run in
the new transaction.
The <ZH>status </>is not updated in the old log.

Use the new log.
