\item A new method, \method{popitem()}, was added to dictionaries to enable
destructively iterating through the contents of a dictionary; this can be faster for large dictionaries because .
\code{D.popitem()} removes a random \code{(\var{key}, \var{value})} pair
from the dictionary and returns it as a 2-tuple. This was implemented
mostly by Tim Peters and Guido van Rossum, after a suggestion and
preliminary patch by Moshe Zadka.

ncurses and of SYSV curses, was contributed by Thomas Gellekum. The

\item The \module{ftplib} module now defaults to retrieving files in passive mode,
because passive mode is more likely to work from behind a firewall.
This request came from the Debian bug tracking system, since other
Debian packages use \module{ftplib} to retrieve files and then don't
work from behind a firewall. It's deemed unlikely that this will
cause problems for anyone, because Netscape defaults to passive mode
and few people complain, but if passive mode is unsuitable for your
application or network setup, call
\method{set_pasv(0)} on FTP objects to disable passive mode.
\item The PyXML package has gone through a few releases since Python
2.0, and Python 2.1 includes an updated version of the \module{xml}
package. Some of the noteworthy changes include support for Expat
1.2, the ability for Expat parsers to handle files in any encoding
supported by Python, and various bugfixes for SAX, DOM, and the
\module{minidom} module.
