Colour 0.3.8

@KelSolaar KelSolaar released this Jul 31, 2016 · 707 commits to develop since this release

Colour 0.3.8 - Alpha Milestone

This release introduces important backward incompatible changes on various spectral computations, illuminants chromaticity coordinates and RGB colourspace model related objects, please carefully refer to the Changes section.

A Jupyter Notebook is available to illustrate the expected computational differences: they should remain orders of magnitude under visual discrimination threshold however they will likely create computational discrepancies.

With Colour 0.3.8, SciPy is now a requirement.

@MichaelMauderer and I would like to thanks all the contributors for that release whether they contribute to the code or participate in discussions.
