Hello,
I'm pleased to announce that Enthought Tool Suite (ETS) version 3.2.0
has been tagged and released!
Source distributions (.tar.gz) have been uploaded to PyPi, and Windows
binaries will be follow shortly. A full install of ETS can be done using
Setuptools via a command like:
easy_install -U "ets[nonets] >= 3.2.0"
NOTE 1: Users of an old ETS release will need to first uninstall prior
to installing the new ETS.
NOTE 2: If you get a 'SandboxViolation' error, simply re-run the command
again -- it may take multiple invocations to get everything installed.
(This error appears to be a long-standing incompatibility between
numpy.distutils and setuptools.)
Please see below for a list of what's new in this release.
What Is ETS?
===========
The Enthought Tool Suite (ETS) is a collection of components developed
by Enthought and the open-source community, 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 on ETS is available from the development home page:

Changelog
=========
ETS 3.2.0 is a feature-added update to ETS 3.1.0, including numerous
bug-fixes. Some of the notable changes include:
Chaco
-----
* Domain limits - Mappers now can declare the "limits" of their valid
domain. PanTool and ZoomTool respect these limits. (pwang)
* Adding "hide_grids" parameter to Plot.img_plot() and
Plot.contour_plot() so users can override the default behavior of hiding
grids. (pwang)
* Refactored examples to declare a Demo object so they can be be run
with the demo.py example launcher. (vibha)
* Adding chaco.overlays package with some canned SVG overlays. (bhendrix)
* DragZoom now can scale both X and Y axes independently corresponding
to the mouse cursor motion along the X and Y axes (similar to the zoom
behavior in Matplotlib). (pwang)
* New Examples:
* world map (bhendrix)
* more financial plots (pwang)
* scatter_toggle (pwang)
* stacked_axis (pwang)
* Fixing the chaco.scales TimeFormatter to use the built-in localtime()
instead of the one in the safetime.py module due to Daylight Savings
Time issues with timedelta. (r23231, pwang)
* Improved behavior of ScatterPlot when it doesn't get the type of
metadata it expects in its "selections" and "selection_masks" metadata
keys (r23121, pwang)
* Setting the .range2d attribute on GridMapper now properly sets the two
DataRange1D instances of its sub-mappers. (r23119, pwang)
* ScatterPlot.map_index() now respects the index_only flag (r23060, pwang)
* Fixed occasional traceback/bug in LinePlot that occurred when data was
completely outside the visible range (r23059, pwang)
* Implementing is_in() on legends to account for padding and alignment
(caused by tools that move the legend) (r23052, bhendrix)
* Legend behaves properly when there are no plots to display (r23012, judah)
* Fixed LogScale in the chaco.scales package to correctly handle the
case when the length of the interval is less than a decade (r22907,
warren.weckesser)
* Fixed traceback when calling copy_traits() on a DataView (r22894, vibha)
* Scatter plots generated by Plot.plot() now properly use the "auto"
coloring feature of Plot. (r22727, pwang)
* Reduced the size of screenshots in the user manual. (r22720, rkern)
Mayavi
------
* 17, 18 March, 2009 (PR):
* NEW: A simple example to show how one can use TVTK’s visual module
with mlab. [23250]
* BUG: The size trait was being overridden and was different from the
parent causing a bug with resizing the viewer. [23243]
* 15 March, 2009 (GV):
* ENH: Add a volume factory to mlab that knows how to set color, vmin
and vmax for the volume module [23221].
* 14 March, 2009 (PR):
* API/TEST: Added a new testing entry point: ‘mayavi -t’ now runs tests
in separate process, for isolation. Added enthought.mayavi.api.test to
allow for simple testing from the interpreter [23195]...[23200],
[23213], [23214], [23223].
* BUG: The volume module was directly importing the wx_gradient_editor
leading to an import error when no wxPython is available. This has been
tested and fixed. Thanks to Christoph Bohme for reporting this issue.
[23191]
* 14 March, 2009 (GV):
* BUG: [mlab]: fix positioning for titles [23194], and opacity for
titles and text [23193].
* ENH: Add the mlab_source attribute on all objects created by mlab,
when possible [23201], [23209].
* ENH: Add a message to help the first-time user, using the new banner
feature of the IPython shell view [23208].
* 13 March, 2009 (PR):
* NEW/API: Adding a powerful TCP/UDP server for scripting mayavi via the
network. This is available in enthought.mayavi.tools.server and is fully
documented. It uses twisted and currently only works with wxPython. It
is completely insecure though since it allows a remote user to do
practically anything from mayavi.
* 13 March, 2009 (GV)
* API: rename mlab.orientationaxes to mlab.orientation_axes [23184]
* 11 March, 2009 (GV)
* API: Expose ‘traverse’ in mlab.pipeline [23181]
* 10 March, 2009 (PR)
* BUG: Fixed a subtle bug that affected the ImagePlaneWidget. This
happened because the scalar_type of the output data from the
VTKDataSource was not being set correctly. Getting the range of any
input scalars also seems to silence warnings from VTK. This should
hopefully fix issues with the use of the IPW with multiple scalars. I’ve
added two tests for this, one is an integration test since those errors
really show up only when the display is used. The other is a traditional
unittest. [23166]
* 08 March, 2009 (GV)
* ENH: Raises an error when the user passes to mlab an array with
infinite values [23150]
* 07 March, 2009 (PR)
* BUG: A subtle bug with a really gross error in the GridPlane
component, I was using the extents when I should really have been
looking at the dimensions. The extract grid filter was also not flushing
the data changes downstream leading to errors that are also fixed now.
These errors would manifest when you use an ExtractGrid to select a VOI
or a sample rate and then used a grid plane down stream causing very
wierd and incorrect rendering of the grid plane (thanks to conflation of
extents and dimensions). This bug was seen at NAL for a while and also
reported by Fred with a nice CME. The CME was then converted to a nice
unittest by Suyog and then improved. Thanks to them all. [23146]
* 28 February, 2009 (PR)
* BUG: Fixed some issues reported by Ondrej Certik regarding the use Of
mlab.options.offscreen, mlab.options.backend = ‘test’, removed cruft
from earlier ‘null’ backend, fixed bug with incorrect imports,
add_dataset set no longer adds one new null engine each time
figure=False is passed, added test case for the options.backend test.
[23088]
* 23 February, 2009 (PR)
* ENH: Updating show so that it supports a stop keyword argument that
pops up a little UI that lets the user stop the mainloop temporarily and
continue using Python [23049]
* 21 February, 2009 (GV)
* ENH: Add a richer view for the pipeline to the MayaviScene [23035]
* ENH: Add safegards to capture wrong triangle array sizes in
mlab.triangular_mesh_source. [23037]
* 21 February, 2009 (PR)
* ENH: Making the transform data filter recordable. [23033]
* NEW: A simple animator class to make it relatively to create
animations. [23036] [23039]
* 20 February, 2009 (PR)
* ENH: Added readers for various image file formats, poly data readers
and unstructured grid readers. These include DICOM, GESigna, DEM,
MetaImage (mha,mhd) MINC, AVSucd, GAMBIT, Exodus, STL, Points, Particle,
PLY, PDB, SLC, OBJ, Facet and BYU files. Also added several tests for
most of this functionality along with small data files. These are
additions from PR’s project staff, Suyog Jain and Sreekanth Ravindran.
[23013]
* ENH: We now change the default so the ImagePlaneWidget does not
control the LUT. Also made the IPW recordable. [23011]
* 18 February, 2009 (GV)
* ENH: Add a preference manager view for editing preferences outside
envisage [22998]
* 08 February, 2009 (GV)
* ENH: Center the glyphs created by barchart on the data points, as
mentioned by Rauli Ruohonen [22906]
* 29 January, 2009 (GV)
* ENH: Make it possible to avoid redraws with mlab by using
mlab.gcf().scene.disable_render = True [22869]
* 28 January, 2009 (PR and GV)
* ENH: Make the mlab.pipeline.user_defined factory function usable to
add arbitrary filters on the pipeline. [22867], [22865]
* 11 January, 2009 (GV)
* ENH: Make mlab.imshow use the ImageActor. Enhance the ImageActor to
map scalars to colors when needed. [22816]
Traits
------
* Fixed a bug whereby faulty error handling in the PyProtocols Pyrex
speedup code keeps references to tracebacks that have been handled. In
so doing, clean up the same code such that it can be used with a modern
Pyrex release (a bare raise can no longer be used outside of an except:
clause).
* RangeEditor factory now supports a 'logslider' mode: Thanks to Matthew
Turk for the patch
* TabularEditor factory now supports editing of all columns: Thanks to
Didrik Pinte for the patch
* DateEditor factory in 'custom' style now supports multi-select feature.
* DateEditor and TimeEditor now support the 'readonly' style.
* Fixed a bug in the ArrayEditor factory that was causing multiple trait
change events to get fired when the underlying array is changed
externally to the editor: Thanks to Matthew Turk for he patch.
* Fixed a circular import error in Color, Font and RGBColor traits
* Fixed a bug in the factory for ArrayViewEditor so it now calls the
toolkit backend-specific editor

* Fixed a bug in the ColorEditor that was causing the revert action to
not work correctly.
* Fixed a bug that caused a traceback when trying to undock a pyface
dock window
