+## 🧪 Migration for v10.0.0-beta.7
+
+### 🛠 MessageState
+
+#### Key Changes:
+
+- `MessageState` factory constructors now accept `MessageDeleteScope` instead of `bool hard` parameter
+- Pattern matching callbacks in state classes now receive `MessageDeleteScope scope` instead of `bool hard`
+- New delete-for-me functionality with dedicated states and methods
+
+#### Migration Steps:
+
+**Before:**
+```dart
+// Factory constructors with bool hard
+final deletingState = MessageState.deleting(hard: true);
+final deletedState = MessageState.deleted(hard: false);
+final failedState = MessageState.deletingFailed(hard: true);
+
+// Pattern matching with bool hard
+message.state.whenOrNull(
+  deleting: (hard) => handleDeleting(hard),
+  deleted: (hard) => handleDeleted(hard),
+  deletingFailed: (hard) => handleDeletingFailed(hard),
+);
+```
+
+**After:**
+```dart
+// Factory constructors with MessageDeleteScope
+final deletingState = MessageState.deleting(
+  scope: MessageDeleteScope.hardDeleteForAll,
+);
+final deletedState = MessageState.deleted(
+  scope: MessageDeleteScope.softDeleteForAll,
+);
+final failedState = MessageState.deletingFailed(
+  scope: MessageDeleteScope.deleteForMe(),
+);
+
+// Pattern matching with MessageDeleteScope
+message.state.whenOrNull(
+  deleting: (scope) => handleDeleting(scope.hard),
+  deleted: (scope) => handleDeleted(scope.hard),
+  deletingFailed: (scope) => handleDeletingFailed(scope.hard),
+);
+
+// New delete-for-me functionality
+channel.deleteMessageForMe(message); // Delete only for current user
+client.deleteMessageForMe(messageId); // Delete only for current user
+
+// Check delete-for-me states
+if (message.state.isDeletingForMe) {
+  // Handle deleting for me state
+}
+if (message.state.isDeletedForMe) {
+  // Handle deleted for me state  
+}
+if (message.state.isDeletingForMeFailed) {
+  // Handle delete for me failed state
+}
+```
+
+> ⚠️ **Important:**  
+> - All `MessageState` factory constructors now require `MessageDeleteScope` parameter
+> - Pattern matching callbacks receive `MessageDeleteScope` instead of `bool hard`
+> - Use `scope.hard` to access the hard delete boolean value
+> - New delete-for-me methods are available on both `Channel` and `StreamChatClient`

+🛑️ Breaking
+
+- **Changed `MessageState` factory constructors**: The `deleting`, `deleted`, and `deletingFailed`

+
+✅ Added

+- Added support for deleting messages only for the current user:
+  - `Channel.deleteMessageForMe()` - Delete a message only for the current user
+  - `StreamChatClient.deleteMessageForMe()` - Delete a message only for the current user via client
+  - `MessageDeleteScope` - New sealed class to represent deletion scope
+  - `MessageState.deletingForMe`, `MessageState.deletedForMe`, `MessageState.deletingForMeFailed` states
+  - `Message.deletedOnlyForMe`, `Event.deletedForMe`, `Member.deletedMessages` model fields
