 -   .NET collection types now implement standard Python collection interfaces from `collections.abc`.
 See [Mixins/collections.py](src/runtime/Mixins/collections.py).

 -   Sign Runtime DLL with a strong name

 -   BREAKING: custom encoders are no longer called for instances of `System.Type`
 -   `PythonException.Restore` no longer clears `PythonException` instance.
 -   Replaced the old `__import__` hook hack with a PEP302-style Meta Path Loader
 -   BREAKING: Names of .NET types (e.g. `str(__class__)`) changed to better support generic types
 -   BREAKING: overload resolution will no longer prefer basic types. Instead, first matching overload will
 be chosen.
