Dec 1, 2025December 2025 monthly summary for Esri/calcite-design-system focusing on design-system modernization and locale-aware UI improvements. Key delivery includes the Calcite Action 5.0 design overhaul with unified Action component design and alignment of related components (accordion-item, alert, block, chip, and button). This work reduces component footprint and enhances embedding flexibility, while standardizing spacing and styling across the Action family. Implemented background color customization with support for transparent appearance and fixed related color, hover, focus, and press states for actionable components. Completed time picker locale enhancements (fr-CA) to align time display with the browser’s locale expectations and simplified internal CSS/utility code to improve maintainability. Updated documentation to revert the deprecation notice for the Action solid appearance to maintain consistency. Overall, these changes improve design system consistency, theming flexibility, localization accuracy, and maintainability, enabling faster UI composition and better cross-component UX.
