2009-08-07 In an effort to simplify the backend API, all clipping rectangles and paths are now passed in using GraphicsContext objects, even on collections and images. Therefore:
        draw_path_collection(self, master_transform, cliprect, clippath,
                             clippath_trans, paths, all_transforms, offsets,

                                        becomes:

        draw_path_collection(self, gc, master_transform, paths, all_transforms,
                             offsets, offsetTrans, facecolors, edgecolors,
                             linewidths, linestyles, antialiaseds, urls)

        draw_quad_mesh(self, master_transform, cliprect, clippath,
                       clippath_trans, meshWidth, meshHeight, coordinates,
                       offsets, offsetTrans, facecolors, antialiased,
                       showedges)

                                        becomes:

        draw_quad_mesh(self, gc, master_transform, meshWidth, meshHeight,
                       coordinates, offsets, offsetTrans, facecolors,
                       antialiased, showedges)

        draw_image(self, x, y, im, bbox, clippath=None, clippath_trans=None)

                                        becomes:

        draw_image(self, gc, x, y, im)

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:
      &#39;cm&#39;:
        The TeX/LaTeX Computer Modern fonts

      &#39;stix&#39;:
        The STIX fonts (see stixfonts.org)

      &#39;stixsans&#39;:
        The STIX fonts, using sans-serif glyphs by default

      &#39;custom&#39;:
        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.

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

2007-10-29 TRANSFORMS REFACTORING
      The primary goal of this refactoring was to make it easier
      to extend matplotlib to support new kinds of projections.
      This is primarily an internal improvement, and the possible
      user-visible changes it allows are yet to come.

      The transformation framework was completely rewritten in
      Python (with Numpy).  This will make it easier to add news
      kinds of transformations without writing C/C++ code.

      Transforms are composed into a &#39;transform tree&#39;, made of
      transforms whose value depends on other transforms (their
      children).  When the contents of children change, their
      parents are automatically updated to reflect those changes.
      To do this an &quot;invalidation&quot; method is used: when children
      change, all of their ancestors are marked as &quot;invalid&quot;.
      When the value of a transform is accessed at a later time,
      its value is recomputed only if it is invalid, otherwise a
      cached value may be used.  This prevents unnecessary
      recomputations of transforms, and contributes to better
      interactive performance.

      The framework can be used for both affine and non-affine
      transformations.  However, for speed, we want use the
      backend renderers to perform affine transformations
      whenever possible.  Therefore, it is possible to perform
      just the affine or non-affine part of a transformation on a
      set of data.  The affine is always assumed to occur after
      the non-affine.  For any transform:

           full transform == non-affine + affine

      Much of the drawing has been refactored in terms of
      compound paths.  Therefore, many methods have been removed
      from the backend interface and replaced with a a handful to
      draw compound paths.  This will make updating the backends
      easier, since there is less to update.  It also should make
      the backends more consistent in terms of functionality.

      User visible changes:

      - POLAR PLOTS: Polar plots are now interactively zoomable,
        and the r-axis labels can be interactively rotated.
        Straight line segments are now interpolated to follow the
        curve of the r-axis.

      - Non-rectangular clipping works in more backends and with
        more types of objects.

      - Sharing an axis across figures is now done in exactly
        the same way as sharing an axis between two axes in the
        same figure:

                 fig1 = figure()
              fig2 = figure()

              ax1 = fig1.add_subplot(111)
              ax2 = fig2.add_subplot(111, sharex=ax1, sharey=ax1)

      - linestyles now include steps-pre, steps-post and
        steps-mid.  The old step still works and is equivalent to
        step-pre.

      - Multiple line styles may be provided to a collection.

      See API_CHANGES for more low-level information about this
      refactoring.
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-

ppinard / matplotlib-colorbar
