Changelog

8.3.0 - 2025-11-19

Added

• Accessibility: New errorBorderColor token in VMessageColorSet for WCAG-compliant form validation borders
• Accessibility: New disabledIcon token in VDefaultThemeProps and VAltThemeProps for disabled icon states
• Accessibility: Six new toggle switch color tokens for disabled states:
  • toggleTrackDisabledOff / toggleTrackDisabledOffDark
  • toggleTrackDisabledOn / toggleTrackDisabledOnDark
  • toggleThumbDisabled / toggleThumbDisabledDark
• VSwitchStyle: New properties for disabled state customization:
  • trackDisabledOff, trackDisabledOn, thumbDisabled
  • borderDisabledOff, borderDisabledOn, thumbBorderDisabled

Changed

• WCAG Compliance: Form validation error borders now use dedicated errorBorderColor token in dark mode
• WCAG Compliance: Toggle switch disabled states now use full opacity colors (#757575 light / #7A7A7A dark) instead of forced opacity
• WCAG Compliance: Disabled icons in VDropdownMenu, VInput, and VSelect now use disabledIcon token with full opacity colors
• Improved contrast ratios across all disabled states to meet WCAG 2.1 Level AA standards

Migration

No breaking changes. All new tokens have sensible defaults. Downstream apps can optionally override the new theme tokens.

VDefaultThemeProps(
  errorBorderColor: yourColor,    // Optional: customize error borders
  disabledIcon: yourColor,         // Optional: customize disabled icons
)

VSwitchStyle(
  trackDisabledOff: yourColor,    // Optional: customize toggle disabled states
  // ... other new properties
)

Fixed

• VPA Accessibility Gaps: Form field error/validation text contrast in dark mode
• VPA Accessibility Gaps: Toggle switch "Off" state contrast in light and dark modes
• VPA Accessibility Gaps: Disabled icon color contrast (Face ID, empty states, dropdowns, inputs)
