I'm pleased to announce that the Enthought Tool Suite (ETS) 3.0.2 has
just been tagged and released!
Source distributions (.tar.gz) have been pushed to PyPi. Window's
binaries will be built and uploaded to PyPi over the next 24 hours or so.
You can update to ETS 3.0.2 like so:
easy_install -U ets>=3.0.2
Changes
-----------
ETS 3.0.2 is an update to ETS 3.0.1 that includes the following changes:
* Update of Enable to fix problems doing 'setup.py install'.
* Update of ETSProjectTools to fix bugs and improve the help messages.
* Update of Mayavi to fix bugs found during the SciPy conference.
* Update of Traits, TraitsGUI, and TraitsBackend* to fix a number of
issues (see
https://svn.enthought.com/enthought/query?milestone=Traits+3.0.2)
What is ETS?
------------------
The Enthought Tool Suite (ETS) is a collection of components developed
by Enthought and our partners, which we use every day to construct
custom scientific applications. It includes a wide variety of
components, including:
* an extensible application framework
* application building blocks
* 2-D and 3-D graphics libraries
* scientific and math libraries
* developer tools
The cornerstone on which these tools rest is the Traits package, which
provides explicit type declarations in Python; its features include
initialization, validation, delegation, notification, and visualization
of typed attributes.
More information is available for all these packages from the Enthought
Tool Suite development home page:

Hello,
We're pleased to announce:
OpenOpt v 0.19, free (license: BSD) optimization framework
(written in Python language) with connections to lots of solvers (some
are C- or Fortran-written) is released.
Changes since previous release 0.18 (June 15, 2008):
* Some changes for NLP/NSP solver ralg (especially related to
handling linear constraints Ax <= b, Aeq x = beq, lb <= x <= ub)
* Bugfix for ralg and IPOPT linear constraints handling
* ALGENCAN v 2.0.x has been connected (v 1.0 is no longer
supported, v 2.0.3 or later is required)
* Bugfix for constrained NLSP graphic output (constrained nssolve
isn't turned to latest ralg version yet)
* Scale parameter for lpSolve (p.scale = {False} | True | 0 | 1)
* New OO class LLAVP (linear least absolute values aka linear
least deviations)
* Improved handling of non-linear functions with restricted dom
* GLP (global) solver galileo now can handle integer problems (via
p.useInteger = 1 or True)
* Another one GLP (global) solver connected: pswarm
* Lots of work related to oofun concept (see OO Doc page for
details)
* Add converters llsp2nlp, llavp2nsp
* Convenient handling of maximization problems (via p.goal = 'max'
or 'maximum')
* Some code clean up and bugfixes
Backward incompatibility:
* Changed objective function in LLSP
* MATLAB-style gradtol renamed to gtol (for to provide same syntax
to scipy.optimize fmin_bfgs, fmin_cg and less-to-type)

Beginning Computer Programming with HLA and PYTHON will provide the
beginner with a tremendous jump start in understanding. The newbie
will readily appreciate the benefits of the High Level instructions in
Python and HLA and the benefits of Low Level instructions in Assembly
after just a little 'hands on' use of each. The reason for these free
online Google Docs is to provide a fun and user friendly, but solid
and quickly productive foundation for new programmers. And Python and
HLA programs will work on today's most popular operating systems, so
you will be well positioned with your programs for future customers.

On behalf of the Python development team and the Python community, I
am happy to announce the first release candidate for Python 2.6.
This is a release candidate, so while it is not suitable for
production environments, we strongly encourage you to download the
release and test it on your software. We expect only critical bugs to
be fixed between now and the final 2.6 release, still scheduled for
October 1st, 2008. There is one more release candidate planned for
September 17th.
You might notice that unlike earlier releases, we are /not/ releasing
Python 3.0rc1 at this time. It was decided that 3.0 still needs time
to resolve open issues and that we would not hold up the 2.6 release
for this. We feel that Python 2.6 is nearly ready for its final
release.
If you find things broken or incorrect, please submit bug reports at
http://bugs.python.org
For more information and downloadable distributions, see the Python
2.6 website:
http://www.python.org/download/releases/2.6/
(Note that the Windows installers will be uploaded shortly.)
See PEP 361 for release schedule details:
http://www.python.org/dev/peps/pep-0361/
Enjoy,
- -Barry

It seems that Py3K (Python 3.0) is just around the corner, so let's
discuss it. If you've played with converting your code to 3.0, are just
toying with the idea, or have gone whole-hog and converted, bring your
experiences to the table. A more general discussion of your strategies
for migrating and maintaining code among different language/library
versions should hopefully emerge.
As usual, we'll be at Linux Caffe (corner of Grace and Harbord, 1 block
South of Christie station), starting around 7pm and going until whenever
on the Third Tuesday of the month.

Have fun all,
Mike

Greetings,
I just wanted to alert everyone of the upcoming, 2nd annual, Python
Texas Regional Unconference which will be held in Austin, TX this year.
http://www.scipy.org/TXUncon2008
This site is a wiki page, so edit away!
Like last year, this Unconference is intended to be a FREE event for
Pythoneers from all over the Texas region to gather and share
experiences and developments. Again, the topics to be presented are
purely up to the participants. Last year there were two main tracks
of talks: Python in Scientific Computing, and Python in Web
Frameworks. We welcome any other presentations as well.
Please see the schedule at the link above and add yourself to the list
of attendees so we'll know you're coming. Please pass along this info
to any other local meetup groups as appropriate.
Please join the list at texas(a)python.org for any discussion or
questions (http://mail.python.org/mailman/listinfo/texas).
Best,
Travis
On behalf of the Jython development team, I'm pleased to announce that
Jython 2.5a3 is available for download at
http://downloads.sourceforge.net/jython/jython_installer-2.5a3.jar.
See the installation instructions here:
http://jython.org/Project/installation.html
Jython 2.5 Alpha3 fixes a bug that caused installation problems for
many Windows users, so Oti Humbel and Leo Soto came to the rescue with
an assist by Geoffrey French. Oti also fixed standalone mode while he
was there. Yay!
As before, this is an alpha release so be careful.
