 * Heap-allocated Types will now incref through :c:func:`PyObject_Init` (and
  its parallel macro PyObject_INIT) instead of :c:func:`PyType_GenericAlloc`.

  All instance allocation C APIs that call
  :c:func:`PyObject_Init` will incref the Type accordingly. This
  includes: :c:func:`PyObject_New`, :c:func:`PyObject_NewVar`,
  :c:func:`PyObject_GC_New`, :c:func:`PyObject_GC_NewVar`, and all their
  corresponding macros.

  To prevent leaks tp_dealloc has be updated to decref the Type if it's not
  already doing so.
