+- **Breaking Change** The `configure(message:indexPath:messagesCollectionView)` method of `LocationMessageCell`,
+`MediaMessageCell`, `TextMessageCell`, and `MessageCollectionViewCell` has been replaced by methods that take the
+delegate return values as arguments.
+[#391](https://github.com/MessageKit/MessageKit/pull/391) by [@SD10](https://github.com/sd10).
+
+- **Breaking Change** The `contentView` property has been renamed to `imageView` for `LocationMessageCell` and `MediaMessageCell`
+and `messageLabel` for `TextMessageCell`.
+[#391](https://github.com/MessageKit/MessageKit/pull/391) by [@SD10](https://github.com/sd10).

 - **Breaking Change** Changed the name of  `MessageInputBar`'s property `maxHeight` to `maxTextViewHeight` as the property is the max height the `InputTextView` can have, not the `MessageInputBar` itself.
