May 1, 2025May 2025 monthly summary for vmware-clarity/ng-clarity: Delivered major UI stability and design-system enhancements. Implemented DataGrid robustness with virtualization under sorting/filtering and keyboard navigation, fixed header and fixed-column rendering, and resolved circular dependency; added shadow DOM aware popovers and outside-click handling. Introduced density tokens and CSS variables with multi-row support, cleaned up unused properties, and updated the density demo. Refactored architecture by making abstract class constructors protected to enforce proper inheritance. Addressed UI consistency with range input height and alignment improvements. These efforts reduce UI glitches, improve performance and developer experience, and enable richer enterprise density configurations.
