Matplotlib

Final planned release for the 1.5.x series.

First bug fix release for 1.5.x series.

This release of matplotlib has several major new features:
- Auto-redraw using the object-oriented API.
- Most plotting functions now support labeled data API.
- Color cycling has extended to all style properties.
- Four new perceptually uniform color maps, including the soon-to-be
default 'viridis'.
- More included style sheets.
- Many small plotting improvements.
- Proposed new framework for managing the GUI toolbar and tools.

This is the last planned bug-fix release in the 1.4 series.

Many bugs are fixed including:
- fixing drawing of edge-only markers in AGG
- fix run-away memory usage when using %inline or saving with
a tight bounding box with QuadMesh artists
- improvements to wx and tk gui backends

Additionally the webagg and nbagg backends were brought closer to
feature parity with the desktop backends with the addition of keyboard
and scroll events thanks to Steven Silvester.
