Hi all,

I am pleased to announce that four new versions of WinPython have been
released yesterday with Python 2.7.6 and 3.3.3, 32 and 64 bits. Many
packages have been added or upgraded (Spyder 2.2.5 for Python 2, Spyder
2.3.0beta2 for Python 3, SciPy 0.13.2, NumPy MKL 1.8.0, IPython 1.0, etc.
-- see the complete changelog:

Special thanks to Christoph Gohlke for building most of the binary packages
bundled in WinPython.

WinPython is a free open-source portable distribution of Python
for Windows, designed for scientists:

It is a full-featured Python-based scientific environment:
  * Designed for scientists (thanks to the integrated libraries
NumPy, SciPy, Matplotlib, guiqwt, etc.:
    * Regular *scientific users*: interactive data processing
and visualization using Python with Spyder
    * *Advanced scientific users and software developers*:
Python applications development with Spyder, version control with
Mercurial and other development tools (like gettext)
  * *Portable*: preconfigured, it should run out of the box on any machine
under Windows (without any installation requirements) and the folder
containing WinPython can be moved to any location (local, network or
removable drive)
  * *Flexible*: one can install (or should I write "use" as it's portable)
as many WinPython versions as necessary (like isolated and self-consistent
environments), even if those versions are running different versions of
Python (2.7, 3.x in the near future) or different architectures (32bit or
64bit) on the same machine
  * *Customizable*: using the integrated package manager (wppm,
as WinPython Package Manager), it's possible to install, uninstall
or upgrade Python packages (see for more details
on supported package formats).

*WinPython is not an attempt to replace Python(x,y)*, this is
just something different: more flexible, easier to maintain, movable and
less invasive for the OS, but certainly less user-friendly, with less
packages/contents and without any integration to Windows explorer [*].

[*] Actually there is an optional integration into Windows
explorer, providing the same features as the official Python installer
regarding file associations and context menu entry (this option may be
activated through the WinPython Control Panel), and adding shortcuts to
Windows Start menu.
