- BREAKING: Methods with `ref` or `out` parameters and void return type return a tuple of only the `ref` and `out` parameters.
- BREAKING: to call Python from .NET `Runtime.PythonDLL` property must be set to Python DLL name
or the DLL must be loaded in advance. This must be done before calling any other Python.NET functions.
- BREAKING: `PyObject.Length()` now raises a `PythonException` when object does not support a concept of length.
- Sign Runtime DLL with a strong name
- Implement loading through `clr_loader` instead of the included `ClrModule`, enables
support for .NET Core
