Supports scaled input values and .3dl input shapers.\r\n\r\n* Full calculation of colour space transforms from chromacities and white points to the working colour space. Now includes DCI-P3 variants, ACES and Adobe RGB and Adobe Wide Gamut RGB.\r\n\r\n* Vectorscope option for preview, with Rec709 75% and 100% boxes, plus a set of Rec709 75% boxes mapped to the current colour space choice.\r\n\r\n* Waveform and RGB parade options for preview.\r\n\r\n* Adjustable knee tool can produce effects from old-school video to smooth hypergamma / cinegamma.\r\n\r\n* ASC CDL controls.\r\n\r\n* New colour control I call 'PSST-CDL' (P)rimary, (S)econdary, (S)kin (T)one colour decision list. Similar controls to ASC-CDL, but operates on specific and tunable areas of a colour wheel. Based on a polar version of YPbPr, but  transformed so that the angle between each primary, secondary (or skin tone) is equal.\r\n\r\n* Colour temperature adjustment as CTO/CTB or from/to colour temperature (scaled mired shifting).\r\n\r\n* Plus / minus green adjustment for fluorescent and LED lighting.\r\n\r\n* False Colour option on LUTs.\r\n\r\n* Web workers, multithreading and typed arrays in place of multidimensional arrays for increased calculation speed, allowing previews.\r\n\r\n* Improved LUTAnalyst code for greater accuracy, more compact binary format option for large (65x65x65) LUTAnalyst files (alongside .cube-based option). Generates a reverse transfer function (gamma) for use as an input / recorded gamma.\r\n\r\n* Additional transfer functions (gammas), primarily around prospective future HDR display functions (eg PQ), plus Panalog and Rec2020 colour space.\r\n\r\n* Comprehensive graphical instructions.\r\n\r\n* Customisation code is now much more organised and consistent, with a well-defined structure.\r\n"}}
