REL: v2.2.2 LTS

The second bug-fix release of the v2.2 LTS series.

This release fixes a number of critical bugs:

 - restores matplotlib.verbose (fixing embedding in pycharm)
 - preserve precision when color mapping small portions of data with
   extreme outliers
 - fixes saving long movies with ffmpeg
 - fixes UnbourdLocal error in contour labeling
 - fixes import failure on python 3.4.0 and 3.4.1
 - fixes compile time failures with clang on 32bit platforms
 - fixes an icon in the Tk backends
 - fixes several issues with Tables
 - fixes expanding offset boxes with tight_layout
 - revert changes to the font caching to avoid a possible bug in
   backports.lru_cache
 - numerous docstring and documentation fixes

We have reverted the deprecation of `font_manager.TempCache`.

v2.2.1 did not actually restore matplotlib.verbose.

REL: v2.2.0 LTS

The first release of the v2.2 LTS series and the last version of
Matplotlib to support python2.  There will be bug-fix release for this
series until 2020.

This release includes new features including:

   (tableau-colorblind10)
 - native support for numpy.datetime64 types
 - animated gif writing via pillow
 - TkAgg now works with pypy
 - cairo based backends for Qt, Tk, and WX

There are several API changes in this release:

   moved to a stand-alone project.

REL: v2.1.0

Matplotlib v2.1.0 release.

This is a major feature release of Matplotlib. This release includes
several major new features such as:
 - improved polar plots
 - string categorical support
 - 'voxel' 3D plots
 - the `Figure` class now has a `subplots` method

and many bug fixes.

REL: v2.1.0rc1

First RC for Matplotlib v2.1

REL: v2.0.2

Critical bug fixes for 2.0.1

 - fixed Qt4 support
 - fixed LogFormatter
 - fixed hatched artists in legends
 - fixed segfault with large images

REL: v2.0.1

Bug fix release for 2.0.x series

This release includes bug fixes, documentation updates and one major change.

API

 - Do not clip the linewidth used for dash pattern scaling.  This is
   an API change, but is a major improvement.
 - Deprecate 'vega' color names in favor of 'tab'.

Bug Fixes

 - Hatching color follows edge color again.
 - Fixes a critical bug with masked images.
 - Improved high-dpi support for Qt5.
 - Log ticking no never skip minor ticks
 - Do not skip points surrounded by nan/inf in vector outputs.

Supported versions of Python

 - 2.7, 3.4, 3.5, 3.6
 - Patches to improve compatibility with pypy

REL: v2.0.0

Major release of Matplotlib

This release completely overhauls the default style of the plots.

Highlights include:

 - 'viridis' is default color map instead of jet.
 - Modernized the default color cycle.
 - Many more functions respect the color cycle.
 - Line dash patterns scale with linewidth.
 - Change default font to DejaVu, now supports most western.
   alphabets (including Greek, Cyrillic and latin with diacritcs),
   math symbols and emoji out of the box.
 - Faster text rendering.
 - Improved auto-limits.
 - Ticks out and only on the right and bottom spines by default.
 - Improved auto-ticking, particularly for log scales and dates.
 - Improved image support (`imshow` respects scales and eliminated a
   class of artifacts).

REL: v2.0.0rc2

This is the second and final planned release candidate for mpl v2.0

This release includes:

 - Bug fixes and documentation changes
 - Expanded API on plot_surface and plot_wireframe
 - Pin font size at text creation time

REL: v2.0.0rc1

This release includes:

 - Deprecation of the 'hold' machinery
 - Bumped the minimum numpy version to 1.7
 - Standardization of hatch width and appearance across backends
 - Made threshold for triggering 'offset' in `ScalarFormatter` configurable
   and default to 4 (plotting against years should just work now)
 - Default encoding for mp4 is now h264
 - `fill_between` and `fill_betweenx` now use the color cycle
 - Default alignment of bars changed from 'edge' to 'center'
 - Bug and documentation fixes
