+* New: Server rpc scope is now bound to cancellation notifications from the client ([#23](https://github.com/marcoferrer/kroto-plus/pull/23))
 * Fix: Race condition between `StreamObserver.onNext` and `StreamObserver.onCompleted` when target channel is full 
 * Fix: Reduce `@KrotoPlusInternalApi` experimental level to `Experimental.Level.ERROR` to prevent external usage  
 * Fix: Remove redundant usages of `@ObsoleteCoroutinesApi` in call builders

-  * **Cooperative cancellation** is propagated across network boundaries. Meaning a cancelled client ```coroutineContext``` attached to a stub will cancel the related rpc job within the service impl.

 * Client Stubs
   * Implement ```CoroutineScope``` interface
   * Designed to work well with **Structured Concurrency**
+  * Cancellation of the client `CoroutineScope` will propagate to the server.
   * Cancellations can now be propagated across usages of a specific stub instance.
   * Rpc methods are overloaded with inline builders for request types
+  * The request parameter for rpc methods defaults to `RequestType.defaultsInstance`
