- Patch #1479181: split open() and file() from being aliases for each other.
-- Patch #1497053: Exceptions occurring in __eq__() methods were always
- silently ignored by dictionaries when comparing keys. They are now
- passed through (except when using the C API function PyDict_GetItem(),
- whose semantics did not change).
+- Patch #1497053 & bug #1275608: Exceptions occurring in ``__eq__()``
+ methods were always silently ignored by dictionaries when comparing keys.
+ They are now passed through (except when using the C API function
+ ``PyDict_GetItem()``, whose semantics did not change).
+
+- Bug #1456209: In some obscure cases it was possible for a class with a
+ custom ``__eq__()`` method to confuse dict internals when class instances
+ were used as a dict's keys and the ``__eq__()`` method mutated the dict.
+ No, you don't have any code that did this ;-)
