 # Changelog
 
+## 2026-01-02 - 3.28.0 - feat(dees-appui)
+Rename DeesAppuiBase to DeesAppui and migrate related API, exports, demos and docs
+
+- Renamed public component/tag and TypeScript types: DeesAppuiBase -> DeesAppui and TDeesAppuiBase -> TDeesAppui; updated IViewActivationContext.appui type accordingly
+- Moved/rewired view registry implementation from dees-appui-base to dees-appui and updated module exports
+- Updated README and demo files to reference DeesAppui and new readme paths (removed dees-appui-base docs/demo)
+- Replaced dependency/imports of '@webcontainer/api' with '@tempfix/webcontainer__api' (package.json and source imports)
+- Changed tsconfig.json: skipLibCheck set from true to false
+
 ## 2026-01-01 - 3.27.1 - fix(dees-actionbar)
 always render actionbar wrapper and delay adding visible class to ensure grid/opacity animations run reliably
