- Added automatic NuGet package generation in appveyor and local builds

- Added function that sets Py_NoSiteFlag to 1.

- Added support for Jetson Nano.

- Added support for__len__ for .NET classes that implement ICollection

- Added`PyExport` attribute to hide .NET types from Python

- Added`__name__` and`__signature__` to reflected .NET methods

- Added PythonException.Format method to format exceptions the same as traceback.format_exception

- Added Runtime.None to be able to pass None as parameter into Python from .NET

- Added PyObject.IsNone() to check if a Python object is None in .NET.

- Fix incorrect dereference of wrapper object in tp_repr, which may result in a program crash

This version improves performance on benchmarks significantly compared to 2.3.

- Support for Python 3.8

- Codecs as the designated way to handle automatic conversions between

.NET and Python types

- Added argument types information to "No method matches given arguments" message

- Moved wheel import in setup.py inside of a try/except to prevent pip collection failures

- Removes PyLong_GetMax and PyClass_New when targetting Python3

- Removes`PyLong_GetMax` and`PyClass_New` when targetting Python3

- Improved performance of calls from Python to C#

- Added support for converting python iterators to C# arrays

- Changed usage of obselete function GetDelegateForFunctionPointer(IntPtr, Type) to GetDelegateForFunctionPointer<TDelegate>(IntPtr)

- 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])

- Changed usage of the obsolete function

`GetDelegateForFunctionPointer(IntPtr, Type)` to

- 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])

- Added support for kwarg parameters when calling .NET methods from Python

- Changed method for finding MSBuild using vswhere

- Reworked`Finalizer`. Now objects drop into its queue upon finalization, which is periodically drained when new objects are created.

- Marked`Runtime.OperatingSystemName` and`Runtime.MachineName` as`Obsolete`, should never have been`public` in the first place. They also don't necessarily return a result that matches the`platform` module's.

- Unconditionally depend on`pycparser` for the interop module generation

- Fixed runtime that fails loading when using pythonnet in an environment

together with Nuitka

- Fixes bug where delegates get casts (dotnetcore)

- Determine size of interpreter longs at runtime

- Handling exceptions ocurred in ModuleObject's getattribute

- Fill`__classcell__` correctly for Python subclasses of .NET types

- Fixed issue with params methods that are not passed an array.

Some features are disabled in Python 3.8.0 because of

`this bug in Python<https://bugs.python.org/issue37633>`_. The error is

``System.EntryPointNotFoundException : Unable to find an entry point named

'Py_CompileString' in DLL 'python38'``. This will be fixed in Python 3.8.1.
