ctypes 0.6.3 released

It's release day ;-)

ctypes 0.6.3 released
=====================

Overview

'ctypes' is a Python package to create and manipulate C data types
in Python, and to call functions in dynamic link libraries/shared
dlls. It allows wrapping these libraries in pure Python.

It works on Windows, Linux and MacOS X (the latter require that
your machine is supported by libffi).


Changes

A critical bug with pointer instances was fixed, this makes the
'incomplete types' sample code in the tutorial actually work.

All ctypes objects are now correctly garbarge collected. This
*may* lead to crashes in your program (especially with callback
functions, or pointers handed out to longer running C code). You
must keep a reference in Python to any object as long as it is
used in foreign C code.

All other known bugs have been fixed.

Again, a lot of changes to the COM package, but all this is still work in
progress and unstable, and it has to be properly documented.

Hi,

I maintain the ctypes Debian package. The following patch allows ctypes to
be built on 64-bit archs.

Cool, thanks. I've applied this in cvs.

PS: Can you post (or send by private email, if it is large, the output
of the test suite: 'python setup.py test' ?
