High Impact

• Resolved Windows crashes and disappearing plotters (see #502)
• Fully dropped support for Python 2.7 (see #493)
• Depth peeling to properly render translucent geometries (see #450)
• Full support for reading/writing files with meshio (see #472 and #495)
• Log scale color mapping (see #499)
• Keyword arguments are now strongly enforced across the API (see #432)
• the IPython tools module has been entirely removed (see #403)
