ST3 4.3.1

4.3.1

• NEW: Upgrade underlying coloraide library to fix a color parsing
  bug.

ST3 4.3.0

4.3.0

• NEW: Upgrade coloraide, along with various improvements brings
  the new HSLuv color space.
• NEW: New coloraide enforces the old Lch gamut mapping as some
  issues with the CSS recommended Oklch were discovered.
• NEW: Add HSLuv based color picker. Can be enabled in the settings.

ST3 4.2.0

4.2.0

• NEW: Upgrade coloraide library which brings back color mapping
  mapping in CIELCH. While interpolation is great in Oklab/Oklch, gamut
  mapping with chroma reduction in Oklch has some less desirable corner
  cases. Using Oklch is in the early stages in the CSS Color Level 4 spec
  and there needs to be more time for this to mature and be tested more.
• NEW: oklab() and oklch() CSS format is now available. This form
  is based on the published CSS Level 4 spec and requires lightness to be
  a percentage. In the future, it is likely that percentages will be
  optional for lightness and could even be applied to some of the other
  components, but currently, such changes are in some early drafts and
  not currently included in ColorHelper.

ST3 4.1.1

4.1.1

• FIX: Fix palette update logic that would not properly format the
  version.

ST3 4.1.0

4.1.0

• NEW: Add minimal color support in Sublime's built-in GraphViz
  syntax files. Colors are currently limited to hex RGB/RGBA and color
  names outside of HTML and full CSS support inside HTML. Support is
  experimental, and if false positives are a problem, the rule can be
  disabled in the settings.
• NEW: Don't default tmtheme custom class output to X11 names,
  default to hex codes instead.
• FIX: Fix some additional custom class issues related to latest
  coloraide update.

ST3 4.0.1

4.0.1

• FIX: Fix built-in custom color class match return. This caused files
  using one of the built-in color classes to fail in creating previews.

ST3 4.0.0

4.0.0

BREAKING CHANGE
If you have defined custom colors rules and specifically reference xyz
rules should be updated to refer to xyz as xyz-d65.

• NEW: Update to latest coloraide which provides minor bug fixes.
  As the new version now includes type annotations, ColorHelper now
  requires the typing dependency until it can be migrated to use Python
  3.8. Typing refactor did moderately affect custom color classes.
• NEW: xyz is now known as xyz-d65 in the settings file.
  If you have custom rules that override or add xyz, please update
  the rules to reference xyz-d65 instead.
• NEW: Gamut mapping now uses Oklch instead of CIE LCH per CSS recnet
  specifications changes to the CSS Level 4 specification.
• NEW: Expose sRGB Linear color space per the CSS specification.
• FIX: Fix blend and blenda regression in emulation of Sublime's
  ColorMod implementation.
• FIX: ColorPicker should not show colors maps with opacity in the
  color map square.

ST3 3.8.0

3.8.0

• NEW: Allow selecting the preview gamut to control what RGB space
  images previews are rendered in. For example, before this change,
  macOS computers with Display P3 monitors would render sRGB colors
  as Display P3 colors and could provide inaccurate previews. Now
  you can set gamut_space to display-p3 and sRGB and Display P3
  colors will be closer to their actual color. Gamut can be set to
  srgb, display-p3, a98-rgb, prophoto-rgb, and rec2020.
  Colors will on only make sense on displays of these types with
  the appropriate color profile enabled. Directly related to
  sublimehq/sublime_text#4930.

ST3 3.7.0

3.7.0

• NEW: Color contrast tool will now take any color space, even non-sRGB,
  but the tool will only operate in the sRGB gamut as the compositing of
  transparent colors defaults to sRGB and the contrast targeting algorithm
  is currently done in the sRGB gamut using HWB. It will more clearly show
  that the color has been gamut mapped in the results as it will now show
  the modified color at all times.
• NEW: Upgrade coloraide which brings the possibility of using CIELuv,
  LCHuv, DIN99o, DIN99o LCH, Okhsl, and Okhsv. Small improvements and fixes
  also included.
• NEW: color(xyz x y z) now references D65 XYZ per latest CSS
  specifications. color(xyz-d50 x y z) is now the old D50 XYZ variant.
  color(xyz-d65 x y z) is also an alias for color(xyz x y z).
• NEW: HSV and HSL store non-hue channels internally in the range of
  0 - 1 instead of 0 - 100. This affects the color(space) output form.
• NEW: Color Picker for HWB is not enabled by default anymore, but can
  be enabled if desired via settings.
• NEW: ColorPicker improvements. Can now configure which color pickers
  are enabled. Can specify a preferred color picker. Can specify whether
  ColorHelper should take a color space and auto load the matching color
  picker if it is enabled. Add new HSV, Okhsl, and Okhsv color pickers.
• NEW: New coloraide dependency may break custom color spaces not
  provided with ColorHelper. If having issues, please open an issue to
  get help. It is doubtful that many have delved too deeply in this area.
• FIX: Fix typos and wording in various color tool dialogs.
• FIX: Better behavior of color picker's handling of color.
• FIX: Fix issues with Advanced Substation Alpha (ASS)
  support.
• FIX: Remove unnecessary dependencies.

ST3 3.6.0

3.6.0

• NEW: Add support for Advanced Substation Alpha (ASS).
