+What's New in Python 3.6.0 beta 1
+=================================
+
+*Release date: 2016-09-12*
+
+Core and Builtins
+-----------------
+
+- Issue #23722: The __class__ cell used by zero-argument super() is now
+ initialized from type.__new__ rather than __build_class__, so class methods
+ relying on that will now work correctly when called from metaclass methods
+ during class creation. Patch by Martin Teichmann.
+
+- Issue #25221: Fix corrupted result from PyLong_FromLong(0) when Python
+ is compiled with NSMALLPOSINTS = 0.
+
+- Issue #27080: Implement formatting support for PEP 515. Initial patch
+ by Chris Angelico.
+
+- Issue #27199: In tarfile, expose copyfileobj bufsize to improve throughput.
+ Patch by Jason Fried.
+
+- Issue #27948: In f-strings, only allow backslashes inside the braces
+ (where the expressions are). This is a breaking change from the 3.6
+ alpha releases, where backslashes are allowed anywhere in an
+ f-string. Also, require that expressions inside f-strings be
+ enclosed within literal braces, and not escapes like
+ f'\x7b"hi"\x7d'.
+
+- Issue #28046: Remove platform-specific directories from sys.path.
+
+- Issue #28071: Add early-out for differencing from an empty set.
+
+- Issue #25758: Prevents zipimport from unnecessarily encoding a filename
+ (patch by Eryk Sun)
+
+- Issue #25856: The __module__ attribute of extension classes and functions
+ now is interned. This leads to more compact pickle data with protocol 4.
+
+- Issue #27213: Rework CALL_FUNCTION* opcodes to produce shorter and more
+ efficient bytecode. Patch by Demur Rumed, design by Serhiy Storchaka,
+ reviewed by Serhiy Storchaka and Victor Stinner.
+
+- Issue #26331: Implement tokenizing support for PEP 515. Patch by Georg Brandl.
+
+- Issue #27999: Make "global after use" a SyntaxError, and ditto for nonlocal.
+ Patch by Ivan Levkivskyi.
+
+- Issue #28003: Implement PEP 525 -- Asynchronous Generators.
+
+- Issue #27985: Implement PEP 526 -- Syntax for Variable Annotations.
+ Patch by Ivan Levkivskyi.
+
+- Issue #26058: Add a new private version to the builtin dict type, incremented
+ at each dictionary creation and at each dictionary change. Implementation of
+ the PEP 509.
+
+- Issue #27364: A backslash-character pair that is not a valid escape sequence
+ now generates a DeprecationWarning. Patch by Emanuel Barry.
+
+- Issue #27350: `dict` implementation is changed like PyPy. It is more compact
+ and preserves insertion order.
+ (Concept developed by Raymond Hettinger and patch by Inada Naoki.)
+
+- Issue #27911: Remove unnecessary error checks in
+ ``exec_builtin_or_dynamic()``.
+
+- Issue #27078: Added BUILD_STRING opcode. Optimized f-strings evaluation.
+
+- Issue #17884: Python now requires systems with inttypes.h and stdint.h
+
+- Issue #27961: Require platforms to support ``long long``. Python hasn't
+ compiled without ``long long`` for years, so this is basically a formality.
+
+- Issue #27355: Removed support for Windows CE. It was never finished,
+ and Windows CE is no longer a relevant platform for Python.
+
+- Implement PEP 523.
+
+- Issue #27870: A left shift of zero by a large integer no longer attempts
+ to allocate large amounts of memory.
+
+- Issue #25402: In int-to-decimal-string conversion, improve the estimate
+ of the intermediate memory required, and remove an unnecessarily strict
+ overflow check. Patch by Serhiy Storchaka.
+
+- Issue #27214: In long_invert, be more careful about modifying object
+ returned by long_add, and remove an unnecessary check for small longs.
+ Thanks Oren Milman for analysis and patch.
+
+- Issue #27506: Support passing the bytes/bytearray.translate() "delete"
+ argument by keyword.
+
+- Issue #27812: Properly clear out a generator's frame's backreference to the
+ generator to prevent crashes in frame.clear().
+
+- Issue #27811: Fix a crash when a coroutine that has not been awaited is
+ finalized with warnings-as-errors enabled.
+
+- Issue #27587: Fix another issue found by PVS-Studio: Null pointer check
+ after use of 'def' in _PyState_AddModule().
+ Initial patch by Christian Heimes.
+
+- Issue #27792: The modulo operation applied to ``bool`` and other
+ ``int`` subclasses now always returns an ``int``. Previously
+ the return type depended on the input values. Patch by Xiang Zhang.
+
+- Issue #26984: int() now always returns an instance of exact int.
+
+- Issue #25604: Fix a minor bug in integer true division; this bug could
+ potentially have caused off-by-one-ulp results on platforms with
+ unreliable ldexp implementations.
+
+- Issue #24254: Make class definition namespace ordered by default.
+
+- Issue #27662: Fix an overflow check in ``List_New``: the original code was
+ checking against ``Py_SIZE_MAX`` instead of the correct upper bound of
+ ``Py_SSIZE_T_MAX``. Patch by Xiang Zhang.
+
+- Issue #27782: Multi-phase extension module import now correctly allows the
+ ``m_methods`` field to be used to add module level functions to instances
+ of non-module types returned from ``Py_create_mod``. Patch by Xiang Zhang.
+
+- Issue #27936: The round() function accepted a second None argument
+ for some types but not for others. Fixed the inconsistency by
+ accepting None for all numeric types.
+
+- Issue #27487: Warn if a submodule argument to "python -m" or
+ runpy.run_module() is found in sys.modules after parent packages are
+ imported, but before the submodule is executed.
+
+- Issue #27157: Make only type() itself accept the one-argument form.
+ Patch by Eryk Sun and Emanuel Barry.
+
+- Issue #27558: Fix a SystemError in the implementation of "raise" statement.
+ In a brand new thread, raise a RuntimeError since there is no active
+ exception to reraise. Patch written by Xiang Zhang.
+
+- Issue #28008: Implement PEP 530 -- asynchronous comprehensions.
+
+Library
+-------
+
+- Issue #28037: Use sqlite3_get_autocommit() instead of setting
+ Connection->inTransaction manually.
+
+- Issue #25283: Attributes tm_gmtoff and tm_zone are now available on
+ all platforms in the return values of time.localtime() and
+ time.gmtime().
+
+- Issue #24454: Regular expression match object groups are now
+ accessible using __getitem__. "mo[x]" is equivalent to
+ "mo.group(x)".
+
+- Issue #10740: sqlite3 no longer implicitly commit an open transaction
+ before DDL statements.
+
+- Issue #17941: Add a *module* parameter to collections.namedtuple().
+
+- Issue #22493: Inline flags now should be used only at the start of the
+ regular expression. Deprecation warning is emitted if uses them in the
+ middle of the regular expression.
+
+- Issue #26885: xmlrpc now supports unmarshalling additional data types used
+ by Apache XML-RPC implementation for numerics and None.
+

+ deprecation include manual creation of SSLSocket and certfile/keyfile
+ (or similar) in ftplib, httplib, imaplib, smtplib, poplib and urllib.
+
+- Issue #28043: SSLContext has improved default settings: OP_NO_SSLv2,
+ OP_NO_SSLv3, OP_NO_COMPRESSION, OP_CIPHER_SERVER_PREFERENCE,
+ OP_SINGLE_DH_USE, OP_SINGLE_ECDH_USE and HIGH ciphers without MD5.
+
+- Issue #24693: Changed some RuntimeError's in the zipfile module to more
+ appropriate types. Improved some error messages and debugging output.
+
+- Issue #17909: ``json.load`` and ``json.loads`` now support binary input
+ encoded as UTF-8, UTF-16 or UTF-32. Patch by Serhiy Storchaka.
+
+- Issue #27137: the pure Python fallback implementation of ``functools.partial``
+ now matches the behaviour of its accelerated C counterpart for subclassing,
+ pickling and text representation purposes. Patch by Emanuel Barry and
+ Serhiy Storchaka.
+
+- Issue #1703178: Fix the ability to pass the --link-objects option to the
+ distutils build_ext command.
