 # Changelog
 
+## 2026-04-07 - 3.62.0 - feat(dees-table)
+add multi-column sorting with header menu controls and priority indicators
+
+- replace single-column sort state with ordered sort descriptors for cascading client-side sorting
+- add Shift+click header sorting, context menu actions, and confirmation before replacing an active sort cascade
+- show multi-sort direction and priority badges in table headers and add a demo showcasing the new behavior
+
 ## 2026-04-06 - 3.61.2 - fix(dees-input-list,dees-icon)
 preserve input focus after list updates and make icons ignore pointer events
