I am very pleased to announce that ETS 3.0.0b1 has just been tagged and

All ETS sub-projects, including Traits, Chaco, Mayavi, and Envisage,
have been tagged and released in one form or another (alpha, beta,
final) as part of this effort. All ETS projects have now been registered
with PyPi and source tarballs have been uploaded! As a result, for the
first time ever, you can now easy_install all of ETS via a simple
command like:
easy_install ETS
Or, alternatively, you can get only specific projects with commands like:
easy_install Mayavi
easy_install Chaco

We anticipate the final release of ETS 3.0, and all of its sub-projects
at their current version number, in a matter of weeks. Please join us in
helping make this final release the most robust release it can be by
participating in this beta shakeout period. Discussions about the status
of ETS and its sub-projects happens on the enthought-dev mailing list,
who's home page is at:

Thank you to all who have worked so hard on making this release possible!

Enthought Tool Suite

The Enthought Tool Suite (ETS) is a collection of components developed
by Enthought and open source participants, 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 the packages
within ETS from the Enthought Tool Suite development home page at


"I set out to rebuild an application in one week that had been developed
over the last seven years (in C by generations of post-docs). Pyface and
Traits were my cornerstones and I knew nothing about Pyface or Wx. It
has been a hectic week. But here ... sits in front of me a nice
application that does most of what it should. I think this has been a
huge success. ... Thanks to the tools Enthought built, and thanks to the
friendly support from people on the [enthought-dev] list, I have been
able to build what I think is the best application so far. I have built
similar applications (controlling cameras for imaging Bose-Einstein
condensate) in C+MFC, Matlab, and C+labWindows, each time it has taken
me at least four times longer to get to a result I regard as inferior.
So I just wanted to say a big "thank you". Thank you to Enthought for
providing this great software open-source. Thank you for everybody on
the list for your replies."

"I'm currently writing a realtime data acquisition/display application …
I'm using Enthought Tool Suite and Traits, and Chaco for display. IMHO,
I think that in five years ETS/Traits will be the most comonly used
framework for scientific applications."
