===========================
**Enhancements**
- 378: SSL security was improved by disabling SSLv2, SSLv3 and SSL_COMPRESSION
features. New TLS_FTPHandler's ssl_options class attribute was added.
- 380: AbstractedFS.listdir() can now return also a generator (not only a
list).
**Bug fixes**
- 367: ThreadedFTPServer no longer hangs if close_all() is called.
- 394: ETIMEDOUT is not treated as an alias for "connection lost".
- 400: QUIT can raise KeyError in case the user hasn't logged in yet and sends
QUIT command.
