Just curious: can you comment on what's similar/different between cairo and 
agg? Is there significant duplication or do they target different problems? 
Would it make sense for these two projects to share code? I worry a bit about 
the explosion of backends, esp. because of the maintainability burden it tends 
to cause in the long term.

No they're not! They are just one of the few visible signs of our evil master 
plan for world domination :)
Best,

This announcement, with links, is available at
http://matplotlib.sf.net/whats_new.html .
What's new in matplotlib-0.64
 * polar plots - polar plots with the polar command. These create a
 axes.PolarAxes instance, which defines the default axes,
 gridlines, etc. Other plot types can be used on polar axes, eg
 scatter. See examples/polar_demo.py, examples/polar_scatter.py
 and screenshot at
 http://matplotlib.sf.net/screenshots.html#polar_demo.
 * cairo backend - Steve Chaplin has contributed cairo and gtkcairo
 backends - http://cairographics.org. Cairo is a vector graphics
 library designed to provide high-quality display and print
 output. Currently supported output targets include the X Window
 System, OpenGL, in-memory image buffers, and image files (PNG and
 PostScript). See http://matplotlib.sf.net/backends.html#Cairo for
 details and install instructions
 * ipython integration - Fernando has continued his excellent work
 integrating matplotlib with ipython and a number of pylab bugs
 have been ironed out. matplotlib has incorporated ipython's
 numutils in the matplotlib.mlab module - See IPython-0.6.4 - all
 similarities betwen matplotlib and ipython version numbers are
 purely coincidental.
 * Jochen Voss has made a number of bugfixes and improvements to the
 postscript backend, including text layout problems. PS backend
 should now be DSC compliant.
 * xticks and yticks now take kwargs so you can do, for example
 xticks( arange(3), ('Tom', 'Dick', 'Harry'), fontsize=14 )
 * imshow now supports PIL images - see examples/image_demo3.py.
 Thanks Andrew Straw.
 * barh for horizontal bar charts. See examples/barh_demo.py
 * added a verbose class to allow different levels of verbosity - see
 http://matplotlib.sf.net/.matplotlibrc for details. Eg, you can
 now do 
 > python myscript.py --verbose-helpful
 to get a lot of information about what matplotlib is doing behind
 the scenes, what resource files are being used etc. The default
 verbose settings and file handles for reporting are customizable
 in rc.
 * numerous small bugfixes and improvements: fixes for gcc-3.4, allow
 -dsomeflag where someflag is not a backend, errorbar now accepts
 barsabove to determine the plot order of the errorbar markers and
 lines, fixed a corrcoef bug where args is a matrix, Andrew Dalke
 contributed code to extend the strftime range to the new matplotlib
 date range, fixes to support for python2.2

Yes, this is meant to be used by figlegend....
JDH

Strike me dumb - please ignore that patch about kwargs in legend.
I just found that patch from last week unsubmitted in my directory. It seemed 
reasonable, so I submitted it. Now i realize, that it was just the 
preparation for a larger change that I never completed.
By itself, this patch is completely pointless (exposing isaxes is nonsense - 
setting this argument to False indicates that the parent is *not* an axes. 
when Legend.__init__ is called by axes.legend, the parent, of course, is - by 
definition - an axes...)

The kwargs to errorbar seem reasonable...
JDH

Hi there,
see attached two tiny patches:
* adding **kwargs to axes.errorbar
* passing **kwargs through axes.legend to Legend()
Greetings,
Nobbi
