+### General
+
+- **Removed Hammer.js dependency**
+    - The `hammerjs` and `@types/hammerjs` peer dependencies have been removed. All touch gesture support (Carousel swipe, Navigation Drawer pan/swipe, List Item pan, Time Picker vertical scroll, Grid Cell double-tap on iOS) is now implemented with native Pointer Events / Touch Events APIs.
+    - `HammerGesturesManager` and related types (`HammerInput`, `HammerStatic`, `HammerManager`, `HammerOptions`) are no longer exported from `igniteui-angular/core`.
+    - The `ng add` schematic no longer prompts for or installs `hammerjs`.
+    - If your application imported `hammerjs` solely for Ignite UI components, you can safely remove it from your `package.json` dependencies, `angular.json` scripts/polyfills, and any `import 'hammerjs'` statements.
