 ### New Features
-`IgxDateRangePicker`
-  - Added cancel button to the dialog, allowing the user to cancel the selection. 
 
-- `IgxCarousel`
-    - Added `select` method overload accepting index.
-    ```ts
-    this.carousel.select(2, Direction.NEXT);
-    ```
 - `IgxGrid`, `IgxTreeGrid`, `IgxHierarchicalGrid`
+    - Introduced a new cell merging feature that allows you to configure and merge cells in a column based on same data or other custom condition, into a single cell.
+
+        It can be enabled on the individual columns:
+
+        ```html
+        <igx-column field="field" [merge]="true"></igx-column>
+        ```
+        The merging can be configured on the grid level to apply either:
+        - `onSort` - only when the column is sorted.
+        - `always` - always, regardless of data operations.
+
+        ```html
+        <igx-grid [cellMergeMode]="'always'">
+        </igx-grid>
+        ```
+
+        The default `cellMergeMode` is `onSort`.
+
+        The functionality can be modified by setting a custom `mergeStrategy` on the grid, in case some other merge conditions or logic is needed for a custom scenario.
+
+        It's possible also to set a `mergeComparer` on the individual columns, in case some custom handling is needed for a particular data field.
+
     - Added ability to pin individual columns to a specific side (start or end of the grid), so that you can now have pinning from both sides. This can be done either declaratively by setting the `pinningPosition` property on the column:
 
-    ```html
-    <igx-column [field]="'Col1'" [pinned]='true' [pinningPosition]='pinningPosition'>
-    </igx-column>
-    ```
+        ```html
+        <igx-column [field]="'Col1'" [pinned]='true' [pinningPosition]='pinningPosition'>
+        </igx-column>
+        ```
 
-    ```ts
-      public pinningPosition = ColumnPinningPosition.End;
-    ```
+        ```ts
+        public pinningPosition = ColumnPinningPosition.End;
+        ```

+        Or with the API, via optional parameter:
 
-    ```ts

         grid.pinColumn('Col1', 0, ColumnPinningPosition.End);
         grid.pinColumn('Col2', 0, ColumnPinningPosition.Start);
-    ```
+        ```
+
+        If property `pinningPosition` is not set on a column, the column will default to the position specified on the grid's `pinning` options for `columns`.

-- `IgxPredefinedRangesAreaComponent`
-  - Added new component for rendering the predefined or custom ranges inside the calendar of the `IgxDateRangePicker`
+    - **Behavioral Changes**
+        - Added cancel button to the dialog, allowing the user to cancel the selection. 
+        - The calendar is displayed with header in `dialog` mode by default.
+        - The picker remains open when typing (in two-inputs and `dropdown` mode).
+        - The calendar selection is updated with the typed value.

+        - The calendar view is updated as per the typed date value.
 
 - `IgxOverlay`
     - Position Settings now accept a new optional `offset` input property of type `number`. Used to set the offset of the element from the target in pixels.
 
 - `IgxTooltip`
     - The tooltip now remains open while interacting with it.
+
 - `IgxTooltipTarget`
     - Introduced several new properties to enhance customization of tooltip content and behavior. Those include `positionSettings`, `hasArrow`, `sticky`, `closeButtonTemplate`.

+  - **Sorting improvements**
+    - Improved sorting algorithm efficiency using Schwartzian transformation. This is a technique, also known as decorate-sort-undecorate, which avoids recomputing the sort keys by temporarily associating them with the original data records.
+    - Refactored sorting algorithms from recursive to iterative.
+  - **Groupby improvements**
