0.1.1

PyPI: https://pypi.org/project/bezier/0.1.1/
Docs: http://bezier.readthedocs.io/en/0.1.1/

Changes:

• Adding Curve.elevate() for degree elevation
• Upgrading curve-curve intersection algorithm to ignore parallel line segments that don't meet (rather than throwing NotImplementedError)
• Making segment_intersection() return a success bool instead of raising NotImplementedError on failure
• Updating docs for newton_refine() with two examples and making parallel_different() a publicly documented function (as a partner to segment_intersection())
• Adding some more examples / failures to curve-curve-intersection doc
