What's new in matplotlib 0.53

Improved font manager and support

   Paul Barrett has thoroughly overhauled font support. FontTools and
   ttfquery are no longer required for font finding as matplotlib now
   has a completely freestanding freetype2 implementation and font
   finder. Among other things, this should enable you to specify fonts
   in your scripts and matplotlibrc file and generate consistent
   figures across backends and operating systems. The font finder
   algorithm and implementation are based on the W3C standard
   http://www.w3.org/TR/1999/REC-CSS1-19990111.

   See the font manager module documentation, the fonts documentation
   http://matplotlib.sf.net/fonts.html and the updated .matplotlibrc
   file for more details; please update your .matplotlibrc.  Thanks
   Paul!

Backend WXAgg

   Antigrain rendering to wxpython applications and figure windows. Now
   wx users have access to all the latest matplotlib functionality,
   including mathtext, antialised drawing, alpha blending and image
   support.

Major and minor ticks

   Full support for major and minor ticks with a bevy of more
   intelligent tick locators supplied in the ticker module. Fully
   customizable and user definable tick locators and formatters. See
   major_minor_demo1.py and major_minor_demo2.py. The default tick
   labeler is much more intelligent is choosing good tick locations.
   See http://matplotlib.sf.net/matplotlib.ticker.html


Date plots

   A new command a plot_date command for plotting date dependent data;
   see http://matplotlib.sf.net/screenshots.html#date_demo. Converters
   supplied in the dates module allow you to work with a variety of
   datetime instances. Custom date locators and formatters allow you to
   place major and minor ticks by minute, hour, weekday, month, year,
   etc, and use strftime format strings to format the ticks. See
   examples date_demo1.py and date_demo2.py. The dates documentation
   provides an overview and guide to with dates -
   see http://matplotlib.sf.net/matplotlib.dates.html.

Ported image support to numarray and postscript backend

   The image module now works with Numeric or numarray, and now works
   in the postscript backend as well as GTKAgg, TkAgg, WXAgg, Agg, and
   GTK.  Thanks to Todd Miller for the PS work!

Changes to matplotlibrc

   Many features added to the default config file for font support,
   tkagg windowing in win32, and more. Please use the new file at
   http://matplotlib.sf.net/.matplotlibrc. By default, the installer
   will overwrite the existing file in the install path, so if you want
   to preserve your's, please move it to your HOME dir and set the
   environment variable if necessary.

load and save commands

   Helper functions for loading and saving ASCII arrays. See load and
   save in the matlab interface.

Two scales on the same axes

   Added some features to the axis and ticks to allow two plots with
   different scales on the "same" axes with different scales, ticks and
   labels on the left and right side of the x axis. To see why same is
   quoted, see examples/two_scales.py.

finance module

   The finance module includes a function to fetch quotes from yahoo,
   to draw candlestick plots, and to draw vertical line plots for
   high-low range with open-close ticks to the left and right. I'm
   hoping that user contributions will make up the bulk of this module
   since I'm not a finance guy! See
   http://matplotlib.sf.net/screenshots.html#date_demo.
