sass/proposal/color-4-new-spaces-js.changes.md

Draft 1.6

• Simplify the type definition for interpolate, and make options argument optional.

• Fix typo in changedValue definition of color.change.

Draft 1.5

• Clarify that deprecated SassColor getters (e.g. red, blue, etc.) convert color to a legacy space before returning channel value.

Draft 1.4

• In change, adjust algorithm for differentiating hwb from hsl when only hue and no space is specified.

• In change for legacy colors, emit a color-4-api warning if a non-alpha channel is explicitly null and no space is set.

• In procedure for Changing a Component Value, specify that undefined values should return the initialValue.

• toSpace uses Converting a Color algorithm instead of color.to-space() to avoid removing missing channels when converting to a legacy space.

• In change and constructors, throw an error for alpha and lightness values that are out of range.

Draft 1.3

• Rename new Embedded Protocol message from SassColor to Color.

• Make color2 a positional parameter of interpolate, not an option.

• Add rec2020 color space.

Draft 1.2

• Add "alpha" to all channel name types.

• Remove isAlphaMissing in favor of isChannelMissing("alpha").

• Rename types using title-case for acronyms longer than two letters in camel-case identifiers (e.g. ColorSpaceHsl instead of ColorSpaceHSL).

• Remove generic change overload, and make space optional on others.

• Return immutable types for channels and channelsOrNull, and remove assumption of 3 channels.

Draft 1.1

• Clarify values in channels and channelsOrNull.

• Throw an error if construction space can not be determined.

• Remove alpha from list of deprecated getters.

• Rename types: ColorSpaceLAB to ColorSpaceLab, ChannelNameLAB to ChannelNameLab.

• Use Exclude<> instead of Omit<> for union types.

• Make procedure for determining space backwards compatible when using change for legacy colors.

• Fix channel names for change with oklch and lch.
