According to the CVS change logs, there were 421 patches applied and
413 bugs fixed between Python 2.3 and 2.4. Both figures are likely to
be underestimates.
This article doesn't attempt to provide a complete specification of
every single new feature, but instead provides a convenient overview.

\item The \module{asyncore} module's \function{loop()} now has a
\var{count} parameter that lets you perform a limited number
of passes through the polling loop. The default is still to loop
forever.
\item The \module{curses} modules now supports the ncurses extension
\function{use_default_colors()}. On platforms where the terminal
supports transparency, this makes it possible to use a transparent
background. (Contributed by J\"org Lehmann.)
\item The \module{base64} module now has more complete RFC 3548 support
for Base64, Base32, and Base16 encoding and decoding, including
optional case folding and optional alternative alphabets.

\item The \module{bisect} module now has an underlying C implementation
for improved performance.

\item The \module{email} package uses a new incremental parser for MIME
message, available in the \module{email.FeedParser} module.
The new parser doesn't require reading the entire message into memory,
and doesn't throw exceptions if a message is malformed; instead it records
any problems as a \member{defect} attribute of the message.

tenfold improvement in speed makes the module suitable for handling
high volumes of data. In addition, the module has two new functions

As usual, there were a bunch of other improvements and bugfixes
scattered throughout the source tree. A search through the CVS change
logs finds there were 421 patches applied and 413 bugs fixed between
Python 2.3 and 2.4. Both figures are likely to be underestimates.
