ftputil 3.1 is now available from
http://ftputil.sschwarzer.net/download .

Changes since version 3.0

- Added support for `followlinks` parameter in `FTPHost.walk`. [1]

- Trying to pickle `FTPHost` and `FTPFile` objects now raises explicit
  `TypeError`s to make clear that not being able to pickle these
  objects is intentional. [2]

- Improved exception messages for socket errors [3].

- Fixed handling of server error messages with non-ASCII characters
  when running under Python 2.x. [4]

- Added a generic "session factory factory" to make creation of
  session factories easier for common use cases (encrypted
  connections, non-default port, active/passive mode, FTP session
  debug level and combination of these). [5] This includes a
  workaround for `M2Crypto.ftpslib.FTP_TLS`; this class won't be
  usable with ftputil 3.0 and up with _just_ the session factory
  recipe described in the documentation. [6]

- Don't assume time zone differences to always be full hours, but
  rather 15-minute units. [7] For example, according to [8], Nepal's
  time zone is UTC+05:45.

- Improved documentation on timeout handling. This includes
  information on internal creation of additional FTP connections (for
  remote files, including uploads and downloads). This may help
  understand better why the `keep_alive` method is limited.

Note that ftputil 3.0 broke backward compatibility with ftputil 2.8
and before. The differences are described here:

What is ftputil?

ftputil is a high-level FTP client library for the Python programming
language. ftputil implements a virtual file system for accessing FTP
servers, that is, it can generate file-like objects for remote files.
The library supports many functions similar to those in the os,
os.path and shutil modules. ftputil has convenience functions for
conditional uploads and downloads, and handles FTP clients and servers
in different timezones.

See the documentation for details:


ftputil is open source software, released under the revised BSD
license (see http://opensource.org/licenses/BSD-3-Clause ).
