I'm pleased to announce the twenty-fifth development release of PythonCAD,
a CAD package for open-source software users. As the name implies,
PythonCAD is written entirely in Python. The goal of this project is
to create a fully scriptable drafting program that will match and eventually
exceed features found in commercial CAD software. PythonCAD is released
under the GNU Public License (GPL).

PythonCAD requires Python 2.2 or newer. The interface is GTK 2.0
based, and uses the PyGTK module for interfacing to GTK. The design of
PythonCAD is built around the idea of separating the interface
from the back end as much as possible. By doing this, it is hoped
that both GNOME and KDE interfaces can be added to PythonCAD through
usage of the appropriate Python module. Addition of other PythonCAD 
interfaces will depend on the availability of a Python module for that
particular interface and developer interest and action.

The twenty-fifth release consists primarily of bug fixes. The compatibility
code for the GTK Action and ActionGroup classes introduced in the previous
release had a number of bugs which have been fixed. People running PythonCAD
on PyGTK releases prior to 2.4 should find this latest release working
correctly due to these fixes. Thanks go to Wilbert Knol for helping identify
and test the proposed fixes for this problem. A number of changes to the
event handling code also are include in this release. Previously various
event handling routines either returned an incorrect value, or returned a
value when not needed. This release cleans up many of these issues, making
the event handling code easier to follow as well as better conforming to
GTK/PyGTK requirements. Various other bug fixes and code enhancements are
present in this release as well.
