10 | 10 | ### Added |
| 11 | +- Added Python 3 buffer api support and PyBuffer interface for fast byte and numpy array read/write ([#980][p980]) |
| 12 | + |
| 13 | +### Changed |
| 14 | +- Drop support for Python 2, 3.4, and 3.5 |
| 15 | +- `clr.AddReference` may now throw errors besides `FileNotFoundException`, that provide more |
| 16 | +details about the cause of the failure |
| 17 | +- `clr.AddReference` no longer adds ".dll" implicitly |
| 18 | +- `PyIter(PyObject)` constructor replaced with static `PyIter.GetIter(PyObject)` method |
| 19 | +- Return values from .NET methods that return an interface are now automatically |
| 20 | + wrapped in that interface. This is a breaking change for users that rely on being |
| 21 | + able to access members that are part of the implementation class, but not the |
| 22 | + interface. Use the new __implementation__ or __raw_implementation__ properties to |
| 23 | + if you need to "downcast" to the implementation class. |
| 24 | + |
| 25 | +### Fixed |
| 26 | + |
| 27 | +- Fix incorrect dereference of wrapper object in `tp_repr`, which may result in a program crash |
| 28 | +- Fix incorrect dereference in params array handling |
| 29 | +- Fix `object[]` parameters taking precedence when should not in overload resolution |
| 30 | +- Fixed a bug where all .NET class instances were considered Iterable |
| 31 | +- Fix incorrect choice of method to invoke when using keyword arguments. |
| 32 | +- Fix non-delegate types incorrectly appearing as callable. |
| 33 | +- Indexers can now be used with interface objects |
| 34 | +- Fixed a bug where indexers could not be used if they were inherited |
| 35 | +- Made it possible to use `__len__` also on `ICollection<>` interface objects |

|
12 | | -- Added automatic NuGet package generation in appveyor and local builds |
13 | | -- Added function that sets Py_NoSiteFlag to 1. |
14 | | -- Added support for Jetson Nano. |
15 | | -- Added support for __len__ for .NET classes that implement ICollection |
16 | | -- Added `PyExport` attribute to hide .NET types from Python |
17 | | -- Added PythonException.Format method to format exceptions the same as traceback.format_exception |
18 | | -- Added Runtime.None to be able to pass None as parameter into Python from .NET |
19 | | -- Added PyObject.IsNone() to check if a Python object is None in .NET. |

| 54 | + .NET and Python types |
22 | 55 |

23 | 56 | ### Changed |
24 | 57 |
|
25 | 58 | - Added argument types information to "No method matches given arguments" message |
26 | 59 | - Moved wheel import in setup.py inside of a try/except to prevent pip collection failures |
27 | | -- Removes PyLong_GetMax and PyClass_New when targetting Python3 |
| 60 | +- Removes `PyLong_GetMax` and `PyClass_New` when targetting Python3 |
28 | 61 | - Improved performance of calls from Python to C# |
29 | 62 | - Added support for converting python iterators to C# arrays |
30 | | -- Changed usage of obselete function GetDelegateForFunctionPointer(IntPtr, Type) to GetDelegateForFunctionPointer<TDelegate>(IntPtr) |
31 | | -- 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]) |
| 63 | +- Changed usage of the obsolete function |
| 64 | + `GetDelegateForFunctionPointer(IntPtr, Type)` to |
| 65 | + `GetDelegateForFunctionPointer<TDelegate>(IntPtr)` |
| 66 | +- When calling C# from Python, enable passing argument of any type to a |
| 67 | + parameter of C# type `object` by wrapping it into `PyObject` instance. |
| 68 | + ([#881][i881]) |
32 | 69 | - Added support for kwarg parameters when calling .NET methods from Python |
33 | 70 | - Changed method for finding MSBuild using vswhere |
34 | | -- Reworked `Finalizer`. Now objects drop into its queue upon finalization, which is periodically drained when new objects are created. |
35 | | -- 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. |

72 | 114 | - 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]) |
