I'm pleased to announce that Enthought Tool Suite (ETS) version 3.3.0 
has been tagged and released!  Please see below for a partial list of 
changes for this release.

PyPi has been updated with the release, including the availability of 
both Windows binaries (.egg) and source distributions (.tar.gz).  A full 
install of ETS can be done using a command like:
    easy_install -U "ETS[nonets] == 3.3.0"

HOWEVER, it is important to note that there are still package 
dependencies that are outside the scope of easy_install.  Therefore, we 
recommend that you have the following installed prior to installing ETS:
    setuptools: minimum version 0.6c9
    VTK: minimum version 5.0, recommended 5.2 or later
And at least one of:
    wxPython: minimum version
    PyQt: minimum version 4.4

For additional installation information, see:

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 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:

ETS 3.3.0 is a feature-added update to ETS 3.2.0, including numerous 
bug-fixes. Some of the notable changes include (sub-projects listed in 
alphabetical order):

Chaco 3.2.0 (July 15, 2009)


  * Bounded grids - Horizontal and Vertical grid line start and end 
points can now be set to a fixed value in data space, or to be the 
return value of an arbitrary callable.  The start and end tick can also 
be configured via the data_min and data_max traits.

  * Added dictionary interface to ArrayPlotData

  * Added a Traits UI view to the ScalesAxis

  * Added a new chaco.overlays subpackage and a new overlay, the DataBox.

  * Improved appearance of PlotToolbar

  * Changed add_default_axis() in the plot_factory module to take an 
axis class as a keyword argument.

  * Refactored contour plots into a common base class and implemented 
proper event handling when their colormaps or data ranges change.

  * Changed default colormap on img_plot() and contour_plot() method of 
Plot to be Spectral instead of Jet.

  * Added two more color palettes to the auto color palette, and created 
a default_colors module.

  * Added CandlePlot renderer

  * Changed Plot Labels to able to display inside the plot area, instead 
of only on the outside

  * Added optional title attribute to plot legends

  * Updated all containers to respect and use the new 
fixed_preferred_size trait on enable.Component

  * New Examples:
    * Interval trait editor as a Chaco example (from Stefan van der Walt)
    * embedding an interactive Chaco plot inside a VTK RenderWindow 
using the new Enable VTK backend
    * lasso tool on an image plot
    * bounded grid
    * candle plot


  * Fixed call signature of ShowAllTickGenerator.get_ticks()
  * Plot.title_font is now a delegate to the underlying PlotLabel object 
(from Chris Colbert)

  * Fixed mouse event handling bug in RangeSelection (from Stefan van 
der Walt)

  * ImagePlots now redraw when their input data changes.

  * Fixed cached image invalidation in colormapped image plots

  * Optimized ScatterPlot.map_index() when index_only is True and the 
index data is sorted

  * Changed ColormappedScatterPlot to no longer incorrectly apply the 
fill_alpha to the outline color

  * Improved date ticking heuristics in chaco.scales subpackage, 
specifically eliminating the bug where all times between, midnight and 
1am would be formatted at too course of a time resolution.

  * Cleanup of various examples (titles, appearance)

  * The spectrum.py (audio spectrograph) example now properly closes the 
audio stream.

enthought.enable Enhancements

 * Added Slider and Compass widgets

 * Added an OverlayContainer (almost identical to the one in Chaco)

a Kiva Image backend-based GraphicsContextEnable

for backwards compatibility, but should be avoided)

 * Moved the scatter_markers module from Chaco to Enable, so that Enable 
components can use MarkerTrait

 * Added an experimental VTK backend for Enable, along with an example

 * Changed SVGButtonEditor toggle to draw a SVG under the button SVG 
instead of drawing a plain box

 * Added labels for SVGButton

 * Improving backbuffering performance on the Mac by creating the layer 
context from the window context instead of from a bitmap.

size preferences can be expressed amongst different components in a 

enthought.enable Fixes

 * Improved the backend selection to match the Traits UI backend unless 
ETSConfig.enable_toolkit is explicitly set
