+- Update to 0.4.0
+  * Use KernelManager's graceful shutdown rather than KILLing kernels
+  * Mimic an Output widget at the frontend so that the Output widget behaves correctly
+  * Nested asyncio is automatic, and works with Tornado
+  * async_execute now has a reset_kc argument to control if the client is reset upon execution request
