+
+### Breaking Changes
+
+- Replaced `ScopedContainerGetterParams` with `SocketEventContext`
+
+  BEFORE:
+
+  ```ts
+  scopedContainerGetter: (args: ScopedContainerGetterParams) => {
+    // ...
+  }
+  ```
+
+  AFTER:
+
+  ```ts
+  scopedContainerGetter: (args: SocketEventContext) => {
+    // ...
+  }
+  ```
+  Note: The new interface contains all properties of the previous
+
+
+### Added
+
+- Added scoped container dispose support  
+- Added interceptor support

+
+To get received message ack use `@MessageAck()` decorator:
+
+```typescript
+import { SocketController, OnMessage, MessageAck, MessageBody } from 'socket-controllers';

+@SocketController()
+export class MessageController {

 You will get a new instance for each event in the controller.
 
-The `scopedContainerGetter` function receives a parameter which contains the socket, socket.io instance, event type, event name, namespace parameters and the message arguments if they are applicable.
+The `scopedContainerGetter` function receives the `SocketEventContext`.
+
+The `scopedContainerDisposer` function receives the container instance you created with `scopedContainerGetter` after the socket action is finished. Use this function to dispose the container if needed.

+## Interceptors
+
+Interceptors allow you to wrap your event handlers in higher order functions.
+With interceptors you can add logging or modify the incoming or outgoing data for event handlers.
+
+```typescript
+import {
+   SocketController,
+   OnMessage,
+   EmitOnSuccess,
+   EmitOnFail,
+   SkipEmitOnEmptyResult,
+   UseInterceptor,
+   MessageBody
+} from 'socket-controllers';
+
+const interceptor: InterceptorInterface = {
+   use: (ctx: SocketEventContext, next: () => any) => {
+     ctx.messageArgs[0] = 'modified message from controller - ' + ctx.messageArgs[0];
+     const resp = next();
+     return 'modified response from controller - ' + resp; // modified response from controller - modified response from method - reponse
+   },
+};
+
+@Service()
+class Interceptor implements InterceptorInterface {
+   async use(ctx: SocketEventContext, next: () => any) {
+     ctx.messageArgs[0] = 'modified message from method - ' + ctx.messageArgs[0];
+     const resp = await next();
+     return 'modified response from method - ' + resp; // modified response from method - reponse
+   }
+}
+
+@SocketController()
+@UseInterceptor(interceptor)
+export class MessageController {
+   @OnMessage('get')
+   @EmitOnSuccess('get_success')
+   @SkipEmitOnEmptyResult()
+   @UseInterceptor(Interceptor)
+   get(@MessageBody() message: string): Promise<Message[]> {
+     console.log(message); // modified message from controller - modified message from method - original message
+     return 'response';
+   }
+}
+```
+
+Interceptors are executed in order of definition, starting with the controller interceptors.
