• Remove deprecated encoding parameter for Python 3.9 compatibility. (5174) • Add support for async kernel management (4479) • Fix typo in password_required help message (5320) • Gateway only: Ensure redirect output messages. This is used to implement the ipywidgets Output widget, for example. • Fix an async bug in message handling by allowing comm message handlers to return a promise which halts message dialog. Other improvements: • Custom KernelManager methods can be Tornado coroutines, allowing async operations. • Make clearing output optional when rewriting input with set_next_input(replace=True)
