CHANGELOG.md

@@ -14,6 +14,7 @@
 - Added loadNewMessagesAfter, loadOldMessagesBefore and removed pagination from getMessages in the ChatRepositoryInterface to change pagination behavior to rely on the stream and two methods indicating that more messages should be added to the stream
 - Added chatTitleResolver that can be used to resolve the chat title from the chat model or return null to allow for default behavior
 - Added ChatPaginationControls to the ChatOptions to allow for more control over the pagination
+- Fixed that chat message is automatically sent when the user presses enter on the keyboard in the chat input
 
 ## 4.0.0
 - Move to the new user story architecture
