This release implements support for Python 3.12 (#1224).

We are now using isort to order our imports. We improved the repository style using the Scientific Python Repository Review page.

colour-visuals was made public: It is a new repository implementing various WebGPU-based visuals on top of Colour and pygfx.

Features

Packaging

We have solved the clash with https://github.com/vaab/colour by loading a known subset of the objects given by vaab/colour-0.1.5 into our namespace if the COLOUR_SCIENCE__COLOUR__IMPORT_VAAB_COLOUR=True environment variable is defined. (#1222, @KelSolaar, @tjdcs, @MichaelMauderer)

See the following issues for more information:

Various new literals have been added to help packages using Colourwith typing annotations. (#1198, @KelSolaar, @jamesmyatt)

Implement support for Apple Log Profile with colour.models.log_encoding_AppleLogProfile and colour.models.log_decoding_AppleLogProfile definitions. (@KelSolaar)

Add new definitions to generate data useful for other plotting definitions and used by colour-visuals: (@KelSolaar)
colour.plotting.lines_daylight_locus
colour.plotting.lines_planckian_locus
colour.plotting.lines_pointer_gamut
colour.plotting.lines_spectral_locus

Ensure that colour.continuous.AbstractContinuousFunction class and sub-classes, e.g. colour.SpectralDistribution class, can be pickled. (#66c26b6, @KelSolaar)

Fix numerical precision issue in colour.difference.delta_E_CIE1994 definition. (#1206, @volrak, @KelSolaar)

Fix issue in colour.utilities.verbose.multiline_repr definition when an attribute representation is None. (#1466, @KelSolaar)

We have changed our unit tests to use np.testing.assert_allclose rather than np.testing.assert_array_almost_equal to help with tests failing on Github Actions because of minor precision issues when using pytest-xdist, multi-threading and caching. (@KelSolaar)
