  - Issue #1469629: Allow cycles through an object's __dict__ slot to be
    collected. (For example if ``x.__dict__ is x``).

 -  (other than a bytes object).
 +- Issue #14205: dict lookup raises a RuntimeError if the dict is modified
 +  during a lookup.

 +  yield from syntax, it needs to have its ``gi_running`` flag set to True.
 +

 +  on the PyObject_Malloc() api like all other objects.
