 ## Key Changes
 
-### Renamed Properties
+### Add action item widgets list for text field
 
-- Renamed `sendBy` field to `sentBy` in `Message` class.
-- Renamed `chatUsers` field to `otherUsers` in `ChatController` class.
+- In this version, we have introduced a new way to add action items to the text field.
+- There are two ways you can add action items at leading and trailing positions of the text field.
+  - `textFieldLeadingActionWidgetBuilder`: This builder allows you to add list of action widgets at the leading position of the text field.
+  - `textFieldTrailingActionWidgetBuilder`: This builder allows you to add list of action widgets at the trailing position of the text field.
+- Add `CameraActionButton` and `GalleryActionButton` widgets as list to leading and trailing builder fo the text field for camera and gallery actions.
+- Now, you can add overlay action button to show overlay action items in the text field. With multiple action items
 
-### Moved Properties
+To show camera and gallery action items in the text field at trailing position, you can use `textFieldTrailingActionWidgetBuilder`. Also, to show the action items in the text field at leading position, you can use `textFieldLeadingActionWidgetBuilder`.
+You can also add custom overlay action items in the text field. As shown in below example:
 
-- Moved `currentUser` field from `ChatView` widget to `ChatController` class.
-
-### Updated Methods
-
-- Updated `id` value in `copyWith` method of `Message` to have correct value.
-- Removed `showTypingIndicator` field from `ChatView` and replaced it with `ChatController.showTypingIndicator`.
