| 1536 | + A security fix alters the :class:`ftplib.FTP` behavior to not trust the | ||
| 1537 | + IPv4 address sent from the remote server when setting up a passive data | ||
| 1538 | + channel. We reuse the ftp server IP address instead. For unusual code | ||
| 1539 | + requiring the old behavior, set a ``trust_server_pasv_ipv4_address`` | ||
| 1540 | + attribute on your FTP instance to ``True``. (See :issue:`43285`) | ||
