          in hist - MM

2008-06-19 Use relative font sizes (e.g. 'medium' and 'large') in
          rcsetup.py and matplotlibrc.template so that text will
          be scaled by default when changing rcParams['font.size'] -
          EF

2008-06-17 Add a generic PatchCollection class that can contain any
          kind of patch. - MGD

2008-06-13 Change pie chart label alignment to avoid having labels
          overwrite the pie - MGD

2008-06-12 Added some helper functions to the mathtext parser to
          return bitmap arrays or write pngs to make it easier to use
          mathtext outside the context of an mpl figure.  modified
          the mathpng sphinxext to use the mathtext png save
          functionality - see examples/api/mathtext_asarray.py - JDH

2008-06-11 Use matplotlib.mathtext to render math expressions in
          online docs - MGD

2008-06-11 Move PNG loading/saving to its own extension module, and

matplotlib 0.98.0 is released
=============================

This is a milestone release of matplotlib with a significant internal
refactoring to support better transformations, path drawing, and
readily extensible coordinate projections and scales.  Michael
Droettboom of STScI did the lion's share of the work, but a large
number of developers have made many significant contributions.  This
is such a significant improvement of the matplotlib code base that we
are jumping from the 0.91 series to the 0.98 series, in anticipation
of rapid progress to 1.0.

Downloads are available at
http://sourceforge.net/project/platformdownload.php?group_id=80706
with binary installers for windows and OS X.  Thanks to Charlie Moad
for the builds and release.

See the migration document at http://matplotlib.sf.net/MIGRATION.txt,
the API changes at http://matplotlib.sf.net/API_CHANGES, and the full
CHANGELOG at http://matplotlib.sf.net/CHANGELOG .  You should manually
any old install of site-packages/matplotlib since the new version will
not properly install over it.

We've also done some work on the look and feel of the web site, with a
new logo an a less jarring color scheme, and are in the midst of a
fairly significant
documentation effort, so if you have any interest in writing documentation or
doing website design, join us on the developers list and ash how you can
contribute.


What's new in matplotlib 0.98
=============================

This is also available on the website at
http://matplotlib.sourceforge.net/whats_new.html


better transformations
----------------------

In what has been described as open-heart surgery on matplotlib,
Michael Droettboom, supported by STScI, has rewritten the transformation
infrastructure from the ground up, which not only makes the code more
intuitive, it supports custom user projections and scales.  See
http://matplotlib.sf.net/doc/devel/add_new_projection.rst and
the http://matplotlib.sf.net/matplotlib.transforms.html module
documentation


proper paths
------------

For the first time, matplotlib supports spine paths across backends,
so you can pretty much draw anything.  See the
http://matplotlib.sf.net/creenshots.html#path_patch_demo screenshot .
Thanks again to Michael Droettboom and STScI.

histogram enhancements
----------------------

hist can handle 2D arrays and create side-by-side or stacked
histograms, as well as cumulative filled and unfilled histograms
http://matplotlib.sf.net/examples/pylab/histogram_demo_extended.py

2D histogram hexbin
-------------------

2D hexagonal bin histogramming with optional log colorscales:
http://matplotlib.sourceforge.net/examples/pylab/hexbin_demo.py

ginput function
---------------

ginput (http://matplotlib.sf.net/matplotlib.pyplot.html#-ginput) is a
blocking function for interactive use to get input from the user.  A
long requested feature submitted by Gael Varoquaux.  See
http://matplotlib.sf.net/examples/pylab/ginput_demo.py.

image optimizations
-------------------

Enhancements to speed up color mapping and panning and zooming on dense images


better savefig
--------------

savefig (http://matplotlib.sf.net/matplotlib.pyplot.html#-savefig) now
supports save to file handles (great for web app servers) or unicode
filenames on all backends


record array functions
----------------------

some more helper functions to facilitate work with record arrays: rec_groupby,
rec2txt, and rec_summarize.  These are found in matplotlib.mlab
(http://matplotlib.sf.net/matplotlib.mlab.html)

accurate elliptical arcs
------------------------

In support of the Phoenix mission to Mars, which used matplotlib in
ground tracking of the spacecraft, Michael Droettboom built on work by
Charlie Moad to provide an extremely accurate 8-spline approximation
to elliptical arcs (see
http://matplotlib.sf.net/matplotlib.patches.html#Arc-draw)win the
viewport.  This provides a scale free, accurate graph of the arc
regardless of zoom level.  See the screenshot and example at
http://matplotlib.sf.net/screenshots.html#ellipse_demo


imread enhanced
---------------

imread (http://matplotlib.sf.net/matplotlib.image.html#-imread) now
will use PIL when available to load images and return numpy arrays

backend enhancements
--------------------

* postscript : the postscript backend has clipping to paths (useful
for polar plots)

* PDF : the PDF backend handles composite glyphs properly, usetex fixes

* SVG : clip to path (useful for polar plots), inkscape cut-and-paste fixes.

* QT : Fixed a duplicate draw bug that slowed performance.  Native qt
       toolbars and status bars used for the toolbar controls

matplotlib 0.91.3 is released
=============================

This is the maintenance bug-fix and feature enhancement release of the
0.91 branch.  Because the 0.98 refactoring introduced more code
breakage than usual, we decided to branch the 0.91 series for users
unable to upgrade right away.  We have ported as many bug fixes and
features to the maintenance branch as possible, and these are now
available for release as 0.91.3.

Could someone tell me the difference between EPD and ETS ?
If I look at the summary, I see
 EPD = ETS + 10 other packages,
but 8 of the 10 other packages are already in ETS ???

Greetings,

Enthought is pleased to announce the release of the Enthought Python  
Distribution (EPD) version 2.5.2001.

http://www.enthought.com/epd

This release makes available both the RedHat 3.x (amd64) and Windows  
XP (x86) installers.  OS X, Ubuntu and more (modern) RHEL versions are  
coming soon(!).


About EPD
---------
The Enthought Python Distribution is a "kitchen-sink-included"  
distribution of the Python Programming Language as well as over 60  
additional tools and libraries.  It includes NumPy, SciPy, IPython, 2D  
and 3D visualization, database adapters and a lot of other tools right  
out of the box.  Enthought is offering access to this bundle as a free  
service to academic and other non-profit organizations.  We also offer  
an annual fee-based subscription service for Commercial and  
Governmental users to download and update the software bundle.  
(Everyone may try it out for free.  Please see the License Information  
below.)


Included Software
-----------------
A short list includes:
Python 2.5.2, NumPy, SciPy, Traits, Mayavi, Chaco, Kiva, Enable,  
Matplotlib, wxPython and VTK.

The complete list of software with version numbers is available here:
http://www.enthought.com/products/epdlibraries.php


License Information
-------------------
EPD is a bundle of software, every piece of which is available  
separately for free under various open-source licenses.  Not-for- 
profit, private-sector access to the bundle and its updates is, and  
will remain, free under the terms of the Subscription Agreement (see http://www.enthought.com/products/epdlicense.php 
  ).  Commercial and Governmental users may try the bundle for free  
for 30 days.  After the trial period, users may purchase a one-year  
subscription to download and update the bundle.  Downloaded software  
obtained under the subscription agreement may be used by the  
subscriber in perpetuity.

This model should sound familiar, as our commercial offering is quite  
similar to the business model of a certain linux distributor.  More  
information is also available in the FAQ ( http://www.enthought.com/products/epdfaq.php 
  ).  For larger deployments, or those with special build or  
distribution needs, an Enterprise Subscription is also available.


Thanks
------
EPD is compelling because it solves a thorny packaging and  
distribution problem, but also because of the libraries which it  
includes.  The folks here at Enthought would like to thank the Python  
developer community and the wider community that authors and  
contributes to these included libraries.  We put these things to work  
every day and would be much less productive without them.  So, thanks!

Travis,
A great initiative! I will attend and will submit an abstract of a
presentation on SimPy (Simulation in Python) and how this project will be
brought closer to SciPy.

Any  idea where in Leipzig the conference will be held? I want to book a
hotel in the vicinity of the conference site.

enhanced mathtext - Complete revamp of matplotlib's internal math
layout and rendering engine. Michael Droetboom has improved the TeX
parser to significantly expand it's coverege, and implemeted Knuth's
box layout algorithms. Additionally, the much anticipated STIX fonts
for math expressions have come online and ship with matplotlib. See a
sample of the new mathtext at
http://matplotlib.sourceforge.net/screenshots.html#mathtext_examples

better configuration - Darren Dale has provided support for a site.cfg
configuration file to enable users and package maintainers to have
better control over the matplotlib build process. He has also provided
a (currently optional) enthought.traits enabled property configuration
to replace matplotlib's rc configuration using a maplotlib.conf file

writing to file-like objects - You can now pass file like objects (eg
StringIO) to all backends for hardcopy. This has been a much requested
feature for usage in web application servers.

record array support - New functions for loading, displaying and
saving numpy record arrays in matplotlib.mlab. See for example,
http://matplotlib.sourceforge.net/examples/loadrec.py

pyplot - Added a module matplotlib.pyplot which has all of pylab's
plotting functions (eg figure, plot, show, close) but does not import
the numpy namepace. This is useful for those who want to use the pylab
functionality w/o the namespace clutter.
http://matplotlib.sourceforge.net/matplotlib.pyplot.html

maskedarray - Added optional support for the scipy sandbox masked
array packaged. Configurable with an rc setting.

plotfile - Added new pylab/pyplot command plotfile for gnuplot style
file plotting

Here is the complete CHANGELOG

===============================================================
2007-11-27 Released 0.91.1 at revision 4517

===============================================================
2007-11-27 Released 0.91.0 at revision 4478

2007-11-13 All backends now support writing to a file-like object, not
          just a regular file.  savefig() can be passed a file-like
          object in place of a file path. - MGD

2007-11-13 Improved the default backend selection at build time:
          SVG -> Agg -> TkAgg -> WXAgg -> GTK -> GTKAgg. The last usable
          backend in this progression will be chosen in the default
          config file. If a backend is defined in setup.cfg, that will
          be the default backend - DSD

2007-11-13 Improved creation of default config files at build time for
          traited config package - DSD

2007-11-12 Exposed all the build options in setup.cfg. These options are
          read into a dict called "options" by setupext.py. Also, added
          "-mpl" tags to the version strings for packages provided by
          matplotlib. Versions provided by mpl will be identified and
          updated on subsequent installs - DSD

2007-11-12 Added support for STIX fonts.  A new rcParam,
          mathtext.fontset, can be used to choose between:

          'cm':
            The TeX/LaTeX Computer Modern fonts

          'stix':
            The STIX fonts (see stixfonts.org)

          'stixsans':
            The STIX fonts, using sans-serif glyphs by default

          'custom':
            A generic Unicode font, in which case the mathtext font
            must be specified using mathtext.bf, mathtext.it,
            mathtext.sf etc.

          Added a new example, stix_fonts_demo.py to show how to access
          different fonts and unusual symbols.

          - MGD

2007-11-12 Options to disable building backend extension modules moved
          from setup.py to setup.cfg - DSD

2007-11-09 Applied Martin Teichmann's patch 1828813: a QPainter is used in
          paintEvent, which has to be destroyed using  the method end(). If
          matplotlib raises an exception before the call to end - and it
          does if you feed it with bad data - this method end() is never
          called and Qt4 will start spitting error messages

2007-11-09 Moved pyparsing back into matplotlib namespace. Don't use
          system pyparsing, API is too variable from one release
          to the next - DSD

2007-11-08 Made pylab use straight numpy instead of oldnumeric
          by default - EF

2007-11-08 Added additional record array utilites to mlab (rec2excel,
          rec2gtk, rec_join, rec_append_field, rec_drop_field) - JDH

2007-11-08 Updated pytz to version 2007g - DSD

2007-11-08 Updated pyparsing to version 1.4.8 - DSD

2007-11-08 Moved csv2rec to recutils and added other record array
          utilities - JDH

2007-11-08 If available, use existing pyparsing installation - DSD

2007-11-07 Removed old enthought.traits from lib/matplotlib, added
          Gael Varoquaux's enthought.traits-2.6b1, which is stripped
          of setuptools. The package is installed to site-packages
          if not already available - DSD

2007-11-05 Added easy access to minor tick properties; slight mod
          of patch by Pierre G-M - EF

2007-11-02 Commited Phil Thompson's patch 1599876, fixes to Qt4Agg
          backend and qt4 blitting demo - DSD

2007-11-02 Commited Phil Thompson's patch 1599876, fixes to Qt4Agg
          backend and qt4 blitting demo - DSD

2007-10-31 Made log color scale easier to use with contourf;
          automatic level generation now works. - EF

2007-10-24 Added ax kwarg to Figure.colorbar and pyplot.colorbar - EF

2007-10-19 Removed a gsave/grestore pair surrounding _draw_ps, which
          was causing a loss graphics state info (see "EPS output
          problem - scatter & edgecolors" on mpl-dev, 2007-10-29)
          - DSD

2007-10-15 Fixed a bug in patches.Ellipse that was broken for
          aspect='auto'.  Scale free ellipses now work properly for
          equal and auto on Agg and PS, and they fall back on a
          polygonal approximation for nonlinear transformations until
          we convince oursleves that the spline approximation holds
          for nonlinear transformations. Added
          unit/ellipse_compare.py to compare spline with vertex
          approx for both aspects. JDH

2007-10-05 remove generator expressions from texmanager and mpltraits.
          generator expressions are not supported by python-2.3 - DSD

2007-10-01 Made matplotlib.use() raise an exception if called after
          backends has been imported. - EF

2007-09-30 Modified update* methods of Bbox and Interval so they
          work with reversed axes.  Prior to this, trying to
          set the ticks on a reversed axis failed with an
          uninformative error message. - EF

2007-09-30 Applied patches to axes3d to fix index error problem - EF

2007-09-24 Applied Eike Welk's patch reported on mpl-dev on 2007-09-22
          Fixes a bug with multiple plot windows in the qt backend,
          ported the changes to backend_qt4 as well - DSD

2007-09-21 Changed cbook.reversed to yield the same result as the
          python reversed builtin - DSD

2007-09-13 The usetex support in the pdf backend is more usable now,
          so I am enabling it. - JKS

2007-09-12 Fixed a Axes.bar unit bug - JDH

2007-09-10 Made skiprows=1 the default on csv2rec - JDH

2007-09-09 Split out the plotting part of pylab and put it in
          pyplot.py; removed numerix from the remaining pylab.py,
          which imports everything from pyplot.py.  The intention
          is that apart from cleanups, the result of importing
          from pylab is nearly unchanged, but there is the
          new alternative of importing from pyplot to get
          the state-engine graphics without all the numeric
          functions.
          Numpified examples; deleted two that were obsolete;
          modified some to use pyplot. - EF

2007-09-08 Eliminated gd and paint backends - EF

2007-09-06 .bmp file format is now longer an alias for .raw

2007-09-07 Added clip path support to pdf backend. - JKS

2007-09-06 Fixed a bug in the embedding of Type 1 fonts in PDF.
          Now it doesn't crash Preview.app. - JKS

2007-09-06 Refactored image saving code so that all GUI backends can
          save most image types.  See FILETYPES for a matrix of
          backends and their supported file types.
          Backend canvases should no longer write their own print_figure()
          method -- instead they should write a print_xxx method for
          each filetype they can output and add an entry to their
          class-scoped filetypes dictionary. - MGD

2007-09-05 Fixed Qt version reporting in setupext.py - DSD

2007-09-04 Embedding Type 1 fonts in PDF, and thus usetex support
          via dviread, sort of works. To test, enable it by
          renaming _draw_tex to draw_tex. - JKS

2007-09-03 Added ability of errorbar show limits via caret or
          arrowhead ends on the bars; patch by Manual Metz. - EF

2007-09-03 Created type1font.py, added features to AFM and FT2Font
          (see API_CHANGES), started work on embedding Type 1 fonts
          in pdf files. - JKS

2007-09-02 Continued work on dviread.py. - JKS

2007-08-16 Added a set_extent method to AxesImage, allow data extent
          to be modified after initial call to imshow - DSD

2007-08-14 Fixed a bug in pyqt4 subplots-adjust. Thanks to
          Xavier Gnata for the report and suggested fix - DSD

2007-08-13 Use pickle to cache entire fontManager; change to using
           font_manager module-level function findfont wrapper for
           the fontManager.findfont method - EF

2007-08-11 Numpification and cleanup of mlab.py and some examples - EF

2007-08-06 Removed mathtext2

2007-07-31 Refactoring of distutils scripts.
          - Will not fail on the entire build if an optional Python
            package (e.g. Tkinter) is installed but its development
            headers are not (e.g. tk-devel).  Instead, it will
            continue to build all other extensions.
          - Provide an overview at the top of the output to display
            what dependencies and their versions were found, and (by
            extension) what will be built.
          - Use pkg-config, when available, to find freetype2, since
            this was broken on Mac OS-X when using MacPorts in a non-
            standard location.

2007-07-30 Reorganized configuration code to work with traited config
          objects. The new config system is located in the
          matplotlib.config package, but it is disabled by default.
          To enable it, set NEWCONFIG=True in matplotlib.__init__.py.
          The new configuration system will still use the old
          matplotlibrc files by default. To switch to the experimental,
          traited configuration, set USE_TRAITED_CONFIG=True in
          config.__init__.py.

2007-07-29 Changed default pcolor shading to flat; added aliases
          to make collection kwargs agree with setter names, so
          updating works; related minor cleanups.
          Removed quiver_classic, scatter_classic, pcolor_classic. - EF

2007-07-26 Major rewrite of mathtext.py, using the TeX box layout model.

          There is one (known) backward incompatible change.  The
          font commands (\cal, \rm, \it, \tt) now behave as TeX does:
          they are in effect until the next font change command or
          the end of the grouping.  Therefore uses of $\cal{R}$
          should be changed to ${\cal R}$.  Alternatively, you may
          use the new LaTeX-style font commands (\mathcal, \mathrm,
          \mathit, \mathtt) which do affect the following group,
          eg. $\mathcal{R}$.

          Other new features include:

          - Math may be interspersed with non-math text.  Any text
            with an even number of $'s (non-escaped) will be sent to
            the mathtext parser for layout.

          - Sub/superscripts are less likely to accidentally overlap.

          - Support for sub/superscripts in either order, eg. $x^i_j$
            and $x_j^i$ are equivalent.

          - Double sub/superscripts (eg. $x_i_j$) are considered
            ambiguous and raise an exception.  Use braces to disambiguate.

          - $\frac{x}{y}$ can be used for displaying fractions.

          - $\sqrt[3]{x}$ can be used to display the radical symbol
            with a root number and body.

          - $\left(\frac{x}{y}\right)$ may be used to create
            parentheses and other delimiters that automatically
            resize to the height of their contents.

          - Spacing around operators etc. is now generally more like
            TeX.

          - Added support (and fonts) for boldface (\bf) and
            sans-serif (\sf) symbols.

          - Log-like function name shortcuts are supported.  For
            example, $\sin(x)$ may be used instead of ${\rm sin}(x)$

          - Limited use of kerning for the easy case (same font)

          Behind the scenes, the pyparsing.py module used for doing
          the math parsing was updated to the latest stable version
          (1.4.6).  A lot of duplicate code was refactored out of the
          Font classes.

          - MGD

2007-07-19 converted non-numpy relicts throughout the code - NN

2007-07-19 replaced the Python code in numerix/ by a minimal wrapper around
          numpy that explicitly mentions all symbols that need to be
          addressed for further numpification - NN

2007-07-18 make usetex respect changes to rcParams. texmanager used to
          only configure itself when it was created, now it
          reconfigures when rcParams are changed. Thank you Alexander
          Schmolck for contributing a patch - DSD

2007-07-17 added validation to setting and changing rcParams - DSD

2007-07-17 bugfix segfault in transforms module. Thanks Ben North for
          the patch. - ADS

          render multiplication sign in offset ticklabel - DSD

2007-07-16 fixed a formatting bug in ticker.ScalarFormatter's scientific
          notation (10^0 was being rendered as 10 in some cases) - DSD

2007-07-13 Add MPL_isfinite64() and MPL_isinf64() for testing
          doubles in (the now misnamed) MPL_isnan.h. - ADS

2007-07-13 The matplotlib._isnan module removed (use numpy.isnan) - ADS

2007-07-13 Some minor cleanups in _transforms.cpp - ADS

2007-07-13 Removed the rest of the numerix extension code detritus,
          numpified axes.py, and cleaned up the imports in axes.py
          - JDH

2007-07-13 Added legend.loc as configurable option that could in
          future default to 'best'. - NN

2007-06-30 Applied patches to tkagg, gtk, and wx backends to reduce
          memory leakage.  Patches supplied by Mike Droettboom;
          see tracker numbers 1745400, 1745406, 1745408.
          Also made unit/memleak_gui.py more flexible with
          command-line options. - EF

2007-06-30 Split defaultParams into separate file rcdefaults (together with
          validation code). Some heavy refactoring was necessary to do so,
          but the overall behavior should be the same as before. - NN

2007-06-27 Added MPLCONFIGDIR for the default location for mpl data
          and configuration.  useful for some apache installs where
          HOME is not writable.  Tried to clean up the logic in
          _get_config_dir to support non-writable HOME where are
          writable HOME/.matplotlib already exists - JDH

2007-06-27 Fixed locale bug reported at

          objects (easier to edit in inkscape). - NN

Hello everyone, I tried to install matplotlib but I am having some problems:

after installing all the necessary prerequisites (cairo, pycairo, pygo..., 
pygtk), I installed MATPLOTLIB as:

python setup.py build
python setup.py install

but when I finally try to use it by calling  >>> from pylab import *
I receive the followinbg error:

Traceback (most recent call last):
  File "<stdin>", line 1, in ?
  File "/usr/local/cdat/lib/python2.4/site-packages/pylab.py", line 1, in ?
    from matplotlib.pylab import *
ImportError: No module named matplotlib.pylab


I hope anyone can help me,

thanks

Once when I found that NumPy released its version 1.0rc3,
I happily upgraded NumPy from 1.0rc1 to 1.0rc3 under WindowsXP.
A nightmare just happened. Matplotlib failed to run with NumPy 1.0rc3,
and I cannot found a NumPy 1.0rc1 on its download page.
Will matplotlib upgrade for NumPy 1.0rc3?
What can I do for this?
Grateful to any suggestion.
Thanks

Again, many thanks to Charlie Moad for handling this release/build.

===============================================================
2006-03-16 Released 0.87.2

2006-03-15 Fixed bug in MaxNLocator revealed by da...@in....
           The main change is that Locator.nonsingular now adjusts
           vmin and vmax if they are nearly the same, not just if
           they are equal.  A new kwarg, "tiny", sets the threshold. -
           EF

2006-03-14 Added import of compatibility library for newer numpy
           linear_algebra - TEO

2006-03-12 Extended "load" function to support individual columns and
           moved "load" and "save" into matplotlib.mlab so they can be
           used outside of pylab -- see examples/load_converter.py -
           JDH

2006-03-12 Added AutoDateFormatter and AutoDateLocator submitted
           by James Evans. Try the load_converter.py example for a

           method to maintain some degree of sanity - DSD

2006-03-11 Added "papertype" savefig kwarg for setting
           postscript papersizes. papertype and ps.papersize
           rc setting can also be set to "auto" to autoscale
           pagesizes - DSD

Hi all,

This is a quick release in advance of scipy this Thursday.  I'm short
on time right now so I'll just paste in the CHANGELOG since the last
release.  I also have not been able to make a binary build for
python2.3 on win32, but there is a 2.4 version.  I'll get this all
sorted out next week.


2005-09-14 Added a new 'resize_event' which triggers a callback with a
           backend_bases.ResizeEvent object.  Not implemented on all

           OR
           fig.resize(400,300)  # pixels

2005-09-07 figure.py: update Figure.draw() to use the updated
           renderer.draw_image() so that examples/figimage_demo.py works again.

This is the second bug fix release of the 0.83 series, but a couple of
new features have crept in....  The notes below include all new
features in 0.83; I've just been a little slow getting them typed up
:-)

You can read these with links at
http://matplotlib.sourceforge.net/whats_new.html


What's new in matplotlib 0.83

axis('scale')

  Added Mark Athen's 'scale' patch, so that on a scaled axis a circle
  looks like circle. See help(axis).

New cursor and span selector widgets

  Added new Cursor and HorizontalSpanSelector to
  matplotlib.widgets. See examples/widgets/cursor.py and
  examples/widgets/span_selector.py. Set useblit = True on gtkagg for
  significantly enhanced performance.

draw events

  You can use use matplotlib event handling to register a callback
  after figure draw using 'draw_event' which calls the callback with a
  DrawEvent instance

  def callback(event):
     #event.renderer is the backend Renderer instance
     pass
  connect('draw_event')


Full screen mode in GTK*

  Use 'f' to toggle full screen mode in the GTK backends.  

GTK and SVG fixes

  Steve Chaplin has made numerous updates to the GTK and SVG
  backends. See the CHANGELOG for details.

Reorganized config files

  Made HOME/.matplotlib the new config dir where the matplotlibrc
  file, the ttf.cache, and the tex.cache live. The new default
  filenames in .matplotlib have no leading dot and are not hidden. Eg,
  the new names are matplotlibrc, tex.cache, and ttffont.cache. This
  is how ipython does it so it must be right. If old files are found,
  a warning is issued and they are moved to the new location. Also
  fixed texmanager to put all files, including temp files in
  ~/.matplotlib/tex.cache, which allows you to usetex in non-writable
  dirs.

Using matplotlib.agg to draw paths

  Updated agg_test.py to demonstrate curved paths and fills.

CocoaAgg

  New CocoaAgg backend for native GUI on OSX, 10.3 and 10.4 compliant.

Qt enhancements

  Applied Ted Drain's QtAgg patch: 1) Changed the toolbar to be a
  horizontal bar of push buttons instead of a QToolbar and updated the
  layout algorithms in the main window accordingly. This eliminates
  the ability to drag and drop the toolbar and detach it from the
  window. 2) Updated the resize algorithm in the main window to show
  the correct size for the plot widget as requested. This works almost
  correctly right now. It looks to me like the final size of the
  widget is off by the border of the main window but I haven't figured
  out a way to get that information yet. We could just add a small
  margin to the new size but that seems a little hacky. 3) Changed the
  x/y location label to be in the toolbar like the Tk backend instead
  of as a status line at the bottom of the widget. 4) Changed the
  toolbar pixmaps to use the ppm files instead of the png files. I
  noticed that the Tk backend buttons looked much nicer and it uses
  the ppm files so I switched them.

mathtext optimizations

  Upgraded pyparsing and applied Paul McGuire's suggestions for
  speeding things up. This more than doubles the speed of mathtext in
  my simple tests.

Bugs fixed / small features 

  Applied SF patches 1242648, 1244732. Fixes SF bugs 1238412, 1231611,
  1209354, subplot (2,1,1) bug,

I created a wiki page on the scipy web site for people to upload tips,
tricks, HOWTOs and recipes for matplotlib.  Everyone is encouraged to
contribute; you just need to get a login for the scipy page from
http://www.scipy.org/wikis/topical_software/join_form .

One easy way to contribute is to take a file from the examples
directory and explain and annotate it and place it on the wiki.  You
can also upload images to show off your work.  Beyond that, everything
is fair game: from a tutorial freezing mpl with py2exe to embedding
mpl in your favorite GUI to doing animations.

To get the ball rolling, I cleaned up my last post to the mailing list
and posted it with a screenshot 

  http://www.scipy.org/wikis/topical_software/MatplotlibCookbook

Thanks to scipy.org and enthought for hosting!

This fixes (we hope) the ipython run bug reported last week on the
mailing list.

Normally, this would have been a bugfix release, but I reorganized the
matplotlib configuration files so thought it best to tick the version
number.  All of the configuration files and dirs (matplotlibrc,
tex.cache, ttffont.cache ) now reside in $HOME/.matplotlib (on windows
C:\Documents and Settings\youracct\.matplotlib).  Please rename your
.matplotlibrc file to matplotlibrc and put it there.

Other change are 


2005-07-07 Added Eric's MA set_xdata Line2D fix - JDH

2005-07-06 Made HOME/.matplotlib the new config dir where the
           matplotlibrc file, the ttf.cache, and the tex.cache live.
           The new default filenames in .matplotlib have no leading
           dot and are not hidden.  Eg, the new names are matplotlibrc
           tex.cache ttffont.cache.  This is how ipython does it so it
           must be right.  If old files are found, a warning is issued
           and they are moved to the new location.  Also fixed
           texmanager to put all files, including temp files in
           ~/.matplotlib/tex.cache, which allows you to usetex in
           non-writable dirs.


2005-07-05 Fixed bug #1231611 in subplots adjust layout.  The problem
           was that the text cacheing mechanism was not using the
           transformation affine in the key. - JDH

           nicer and it uses the ppm files so I switched them.


2005-06-17 Modified the gtk backend to not queue mouse motion events.
           This allows for live updates when dragging a slider. - CM

2005-06-17 Added starter CocoaAgg backend.  Only works on OS 10.3 for
           now and requires PyObjC.  (10.4 is high priority) - CM

2005-06-17 Upgraded pyparsing and applied Paul McGuire's suggestions
           for speeding things up.  This more than doubles the speed
           of mathtext in my simple tests. JDH

2005-06-16 Applied David Cooke's subplot make_key patch
