Direct instantiation of SSLSocket and SSLObject objects is now prohibited.
The constructors were never documented, tested, or designed as public
constructors. Users were suppose to use ssl.wrap_socket() or SSLContext.

Remove the tri-state parameter "hash", and add the boolean "unsafe_hash". If
unsafe_hash is True, add a __hash__ function, but if a __hash__ exists,
raise TypeError. If unsafe_hash is False, add a __hash__ based on the
values of eq= and frozen=. The unsafe_hash=False behavior is the same as
the old hash=None behavior. unsafe_hash=False is the default, just as
hash=None used to be.

.. section: Library
``_abc`` module is added. It is a speedup module with C implementations for
various functions and methods in ``abc``. Creating an ABC subclass and
calling ``isinstance`` or ``issubclass`` with an ABC subclass are up to 1.5x
faster. In addition, this makes Python start-up up to 10% faster.
Note that the new implementation hides internal registry and caches,
previously accessible via private attributes ``_abc_registry``,
``_abc_cache``, and ``_abc_negative_cache``. There are three debugging
helper methods that can be used instead ``_dump_registry``,
``_abc_registry_clear``, and ``_abc_caches_clear``.

:func:`fnmatch.translate()` no longer produces patterns which contain set
operations. Sets starting with '[' or containing '--', '&&', '~~' or '||'
will be interpreted differently in regular expressions in future versions.
Currently they emit warnings. fnmatch.translate() now avoids producing
patterns containing such sets by accident.
