CRAN version 2.4.0

NEW FEATURES AND SIGNIFICANT CHANGES

• Fixed a bug introduced in version 2.3.0 that gave wrong values for S1UV and
  S1V in summary.rspec().
• several plot() functions for colspace (triplot(), tcsplot(),
  tetraplot()) gain a new gamut argument to plot the maximum gamut for a given
  visual system and illuminant. summary.colspace() also now returns the maximum
  colour volume for a given visual system and illuminant that you can use to
  compare to the realised volume by a given dataset. More information in PR #180.
• parallel processing now relies on the future package, which offers windows
  and high performance computing (HPC) environments support. The progress bar is
  produced by the progressr package and can be customised as well. As a
  consequence, the cores argument in getspec(), adjacent() and classify()
  has been deprecated.

MINOR FEATURES AND BUG FIXES

• fixed a plotting bug introduced in version 2.3.0 where it was required to run
  projplot() twice for the background grid to be displayed.
• fixed a bug in summary.colspace() where NULL was returned instead of
  summary.data.frame() for non-tcs colourspaces.
• fix partial matching warnings in examples and in bootcooldist()
• the package has a new website at pavo.colrverse.com
• fixed a bug in coldist()that prevented the calculation of achromatic contrast
  when using custom quantum catch data
