[ANNOUNCE] python-gtkmvc 1.99.0

	Version 1.99.0 of pygtkmvc has been released. 

Project homepage:
<http://apps.sourceforge.net/trac/pygtkmvc/wiki>

Download:
<http://sourceforge.net/projects/pygtkmvc/>

==============
About pygtkmvc
==============

pygtkmvc is a fully Python-based implementation of the
Model-View-Controller (MVC) and Observer patterns for the PyGTK2
toolkit.

MVC is a pattern that can be successfully used to design and
develop well structured GUI applications. The MVC pattern
basically helps in separating semantics and data of the
application, from their representation.

The Observer pattern helps to weaken dependencies among parts that
should be separated, but need to be connected each other.

pygtkmvc provides a powerful and still simple infrastructure to
help designing and implement GUI applications based on the MVC and
Observer patterns.

The framework has been designed to be:

PyOpenGL Release 3.0.0 (final)

PyOpenGL is the traditional OpenGL binding for the Python language 
(Python 2.x series).  This release is the first major release of the 
package in more than 4 years.  PyOpenGL 3.x is a complete rewrite of the 
PyOpenGL project which attempts to retain compatibility with the 
original PyOpenGL 2.x API while providing support for many more 
data-formats and extensions than were wrapped by the previous 
code-base.  It attempts to retain the "easy" approachable API of the 
original PyOpenGL bindings, focusing more on ease of development (both 
for client code and the library itself) than speed.

Build and installation has been dramatically simplified.  It is possible 
to work directly from a PyOpenGL bzr branch or to merely unpack the 
package into your PYTHONPATH.  To install from source and/or participate 
in development:

    bzr branch lp:pyopengl
    bzr branch lp:pyopengl-demo

then add the pyopengl/OpenGL directory to your PYTHONPATH.  You can also 
download the source distributions from:

    http://pyopengl.sourceforge.net

and use standard distutils commands to install.  PyOpenGL 3.x is already 
supported by the PyInstaller "exe" packaging utility, and can be made to 
work with Py2exe with inclusion statements.

PyOpenGL may be installed using the easy_install script if desired.  
There are no setuptools/package-resources dependencies in PyOpenGL 3.0.0 
final.  You can install PyOpenGL on supported platforms (currently

pyspread 0.0.11 released


pyspread 0.0.11 released
========================

Homepage:
---------

http://pyspread.sf.net

 
About: 
------

Pyspread is a cross-platform spreadsheet application that is based on
and written in the programming language Python.

Pyspread provides an arbitrary size, three-dimensional grid for
spreadsheet calculations. Each grid cell accepts a Python expression.
Therefore, no spreadsheet specific language has to be learned.
Python modules are usable from the spreadsheet table without external
scripts.

Pyspread runs on Linux, Windows and *nix platforms with GTK+ support. I
have reports that it works with MacOS X as well.

New features in 0.0.11:
-----------------------

* Recursion detection for slicing operations added
* Dependency to networkx added

[RELEASED] Python 3.1 alpha 2

On behalf of the Python development team, I'm thrilled to announce the second
alpha release of Python 3.1.

Python 3.1 focuses on the stabilization and optimization of features and changes
Python 3.0 introduced.  For example, the new I/O system has been rewritten in C
for speed.  Other features include an ordered dictionary implementation and
support for ttk Tile in Tkinter.  For a more extensive list of changes in 3.1,
see http://doc.python.org/dev/py3k/whatsnew/3.1.html or Misc/NEWS in the Python
distribution.

Please note that this is an alpha releases, and as such is not suitable for
production environments.  We continue to strive for a high degree of quality,
but there are still some known problems and the feature sets have not been
finalized.  This alpha is being released to solicit feedback and hopefully
discover bugs, as well as allowing you to determine how changes in 3.1 might
impact you.  If you find things broken or incorrect, please submit a bug report
at

     http://bugs.python.org

For more information and downloadable distributions, see the Python 3.1 website:

     http://www.python.org/download/releases/3.1/

See PEP 375 for release schedule details:

     http://www.python.org/dev/peps/pep-0375/
