+Instance Method Objects
+-----------------------
+
+.. index:: object: instancemethod
+
+An instance method is a wrapper for a :cdata:`PyCFunction` and the new way
+to bind a :cdata:`PyCFunction` to a class object. It replaces the former call
+:cfunc:`PyMethod_New(func, NULL, class)`.
+
+
+.. cvar:: PyTypeObject PyInstanceMethod_Type
+
+   This instance of :ctype:`PyTypeObject` represents the Python instance
+   method type. It is not exposed to Python programs.
+
+
+.. cfunction:: int PyInstanceMethod_Check(PyObject *o)
+
+   Return true if *o* is an instance method object (has type
+   :cdata:`PyInstanceMethod_Type`).  The parameter must not be *NULL*.
+
+
+.. cfunction:: PyObject* PyInstanceMethod_New(PyObject *func)
+
+   Return a new instance method object, with *func* being any callable object
+   *func* is is the function that will be called when the instance method is
+   called.
+
+
+.. cfunction:: PyObject* PyInstanceMethod_Function(PyObject *im)
+
+   Return the function object associated with the instance method *im*.
+
+
+.. cfunction:: PyObject* PyInstanceMethod_GET_FUNCTION(PyObject *im)
+
+   Macro version of :cfunc:`PyInstanceMethod_Function` which avoids error checking.

 Core and Builtins
 -----------------
 
+- Issue #1587: Added instancemethod wrapper for PyCFunctions. The Python C API
+  has gained a new type *PyInstanceMethod_Type* and the functions
+  *PyInstanceMethod_Check(o)*, *PyInstanceMethod_New(func)* and
+  *PyInstanceMethod_Function(im)*.
+
 - Constants gc.DEBUG_OBJECT and gc.DEBUG_INSTANCE have been removed from the
   gc module; gc.DEBUG_COLLECTABLE or gc.DEBUG_UNCOLLECTABLE are now enough to
   print the corresponding list of objects considered by the garbage collector.
