This may be needed if you've edited data on an instance indirectly (eg, modifying an array reference on the object), and need to force a change notification to update some dependent data.
In Python, this can be done by passing unreal.PropertyAccessChangeNotifyMode.ALWAYS as the notify_mode argument to set_editor_property.
In Editor Utilities, there is a new advanced pin available for setting the "Change Notify Mode".
In both cases the default method is to notify only when the value actually changes.
This change also significantly simplifies UK2Node_GetEditorProperty and UK2Node_SetEditorProperty by having them derive from UK2Node_CallFunction, rather than being a proxy node that expands to a UK2Node_CallFunction node.

This avoids the caller needing to have called unreal.get_blueprint_generated_types(...) for the type before trying to access it.

This is the first phase of allowing Blueprint types to be generated for Python, which must be accessed via unreal.get_blueprint_generated_types(...) as asset names are not guaranteed to be unique, so they're not added to the unreal module.
Once a type has been generated for Python, it will be updated if the underlying asset is changed. Should the asset be deleted then the Python type will be reset to clean state and become mostly unusable.
This change also ensures that the Unreal type pointers referenced by the Python meta-data are ARO'd correctly. This will cause a warning if you try and delete an asset with a type used by Python.
MyEnum = unreal.get_blueprint_generated_types('/Game/MyEnum') # This can also accept multiple arguments or a list, and will return a tuple of types
print(MyEnum.MY_ENTRY)

The existing Python code has been ported to use this, and this can also be used by Blueprints (or other C++ setting properties) to allow property changes that emit change notifications.
