 -   Reattach python exception traceback information (#545)
 -   PythonEngine.Intialize will now call `Py_InitializeEx` with a default value of 0, so signals will not be configured by default on embedding. This is different from the previous behaviour, where `Py_Initialize` was called instead, which sets initSigs to 1. ([#449][i449])
 -   Refactored MethodBinder.Bind in preparation to make it extensible (#829)
--   When calling C# from Python, enable passing argument of any type to a parameter of C# type `object` by wrapping it into `PyObject` instance. ([#881][i881])
 -   Look for installed Windows 10 sdk's during installation instead of relying on specific versions.
