+**@nestjs/core**
+- `@Pipe()` feature (async & sync),
+- Exception Filters can have global, controller and method scope.

+**@nestjs/websockets - BREAKING CHANGE**
+- Use `useWebSocketAdapter()` instead of `setIoAdapter()`,

+
+**@nestjs/microservices - BREAKING CHANGE**
+- Now methods have to return `Observable`, and they receive only one argument `data`,
+- Microservices can return multiple values, but after emitting `Observable` has to be COMPLETED!
