! \section{Other Changes and Fixes}

! % XXX update the patch and bug figures as we go
! 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 43 patches applied, and 77 bugs fixed; both
! figures are likely to be underestimates.  Some of the more notable
! changes are:

  \begin{itemize}

-   \item Keyword arguments passed to builtin functions that don't take them
-   now cause a \exception{TypeError} exception to be raised, with the
-   message "\var{function} takes no keyword arguments".
-   
-   \item The code for the Mac OS port for Python, maintained by Jack
-   Jansen, is now kept in the main Python CVS tree.
- 
-   \item The new license introduced with Python 1.6 wasn't
-   GPL-compatible.  This is fixed by some minor textual changes to the
-   2.2 license, so Python can now be embedded inside a GPLed program
-   again.  The license changes were also applied to the Python 2.0.1
-   and 2.1.1 releases.
- 
    \item Profiling and tracing functions can now be implemented in C,
    which can operate at much higher speeds than Python-based functions

! 
!   \item New constants \constant{ascii_letters},
!   \constant{ascii_lowercase}, and \constant{ascii_uppercase} were
!   added to the \module{string} module.  There were several modules in
!   the standard library that used \constant{string.letters} to mean the
!   ranges A-Za-z, but that assumption is incorrect when locales are in
!   use, because \constant{string.letters} varies depending on the set
!   of legal characters defined by the current locale.  The buggy
!   modules have all been fixed to use \constant{ascii_letters} instead.

! \section{Interpreter Changes and Fixes}

! Some of the changes only affect people who deal with the Python
! interpreter at the C level, writing Python extension modules,
! embedding the interpreter, or just hacking on the interpreter itself.
! If you only write Python code, none of the changes described here will
! affect you very much.

!   \item When presented with a Unicode filename on Windows, Python will
!   now correctly convert it to a string using the MBCS encoding.
!   Filenames on Windows are a case where Python's choice of ASCII as
!   the default encoding turns out to be an annoyance.

!   \item A new \samp{et} format sequence was added to
!   \cfunction{PyArg_ParseTuple}; \samp{et} takes both a parameter and
!   an encoding name, and converts the parameter to the given encoding
!   if the parameter turns out to be a Unicode string, or leaves it
!   alone if it's an 8-bit string, assuming it to already be in the
!   desired encoding.  This differs from the \samp{es} format character,
!   which assumes that 8-bit strings are in Python's default ASCII
!   encoding and converts them to the specified new encoding.
!   (Contributed by M.-A. Lemburg, and used for the MBCS support on
!   Windows described in the previous section.)
!    
!   \item Two new wrapper functions, \cfunction{PyOS_snprintf()} and
!   \cfunction{PyOS_vsnprintf()} were added.   which provide a cross-platform
!   implementations for the relatively new snprintf()/vsnprintf() C lib
!   APIs. In contrast to the standard sprintf() and vsprintf() C lib
!   APIs, these versions apply bounds checking on the used buffer which
!   enhances protection against buffer overruns.
