 # Changelog
 
+## 2026-04-11 - 3.71.1 - fix(dees-modal)
+move modal content scrolling into dees-tile so long content stays scrollable with pinned header and actions
+
+- Update dees-tile content area to use vertical scrolling when constrained by a max-height while keeping horizontal overflow clipped.
+- Remove duplicate scrolling styles from dees-modal and rely on the shared tile container behavior.
+- Add modal demo cases for long article, list, and form content to verify internal scrolling.
+
 ## 2026-04-11 - 3.71.0 - feat(dees-stepper)
 add footer menu actions with form-aware step validation
