@@ -14,12 +14,20 @@ This document follows the conventions laid out in [Keep a CHANGELOG][].
1414
-`clr.AddReference` may now throw errors besides`FileNotFoundException`, that provide more
1515
details about the cause of the failure
1616
-`clr.AddReference` no longer adds ".dll" implicitly
17+
-`PyIter(PyObject)` constructor replaced with static`PyIter.GetIter(PyObject)` method
18+
- Return values from .NET methods that return an interface are now automatically
19+
wrapped in that interface. This is a breaking change for users that rely on being
20+
able to access members that are part of the implementation class, but not the
21+
interface. Use the new__implementation__ or__raw_implementation__ properties to
22+
if you need to "downcast" to the implementation class.

###Fixed

2026
- Fix incorrect dereference of wrapper object in`tp_repr`, which may result in a program crash
2127
- Fix incorrect dereference in params array handling
2228
- Fix`object[]` parameters taking precedence when should not in overload resolution
29+
- Fixed a bug where all .NET class instances were considered Iterable
30+
- Fix incorrect choice of method to invoke when using keyword arguments.
