v2.0.0

Changes

• this project was removed from postcss-modules-values to keep new convention and note folks about icss
• values names started with dot and hash (.5s, #hash) are not longer allowed and pushed warnings to introduce selector value replacement (yeah :external() like feature for theming)
• redeclared values push warnings to keep things immutable
• Path replacement feature is removed because of reducing maintainability such values (@colors: './path'; @value one from colors;)
