 ### Changed
 
 - Update code for Swift 6.3.
-- Raise the minimum supported macOS version to 15.
 - Return `nil` for out-of-range hexadecimal color values instead of asserting.
 - Return `nil` for CSS color codes with out-of-range numeric components.
 
 
+### Breaking Changes
+
+- Raise the minimum supported macOS version to 15.
+- Add `.shortHexWithAlpha`, `.cssHWB`, and `.cssHWBWithAlpha` cases to `ColorCodeType`; apps with exhaustive switches over the enum need updates.
+- Change `ColorCodeType` raw values to match the case order; apps that persist or exchange the raw integer values need migration.

 ### Deprecated
