-What's New in Python 3.7.0 alpha 1?
-===================================
-
-*Release date: XXXX-XX-XX*
-
-Core and Builtins
------------------
-
-- bpo-31161: Make sure the 'Missing parentheses' syntax error message is
- only applied to SyntaxError, not to subclasses. Patch by Martijn Pieters.
-
-- bpo-30814: Fixed a race condition when import a submodule from a package.
-
-- bpo-30736: The internal unicodedata database has been upgraded to Unicode
- 10.0.
-
-- bpo-30604: Move co_extra_freefuncs from per-thread to per-interpreter to
- avoid crashes.
-
-- bpo-30597: ``print`` now shows expected input in custom error message when
- used as a Python 2 statement. Patch by Sanyam Khurana.
-
-- bpo-30682: Removed a too-strict assertion that failed for certain f-strings,
- such as eval("f'\\\n'") and eval("f'\\\r'").
-
-- bpo-30501: The compiler now produces more optimal code for complex condition
- expressions in the "if", "while" and "assert" statement, the "if" expression,
- and generator expressions and comprehensions.
-
-- bpo-28180: Implement PEP 538 (legacy C locale coercion). This means that when
- a suitable coercion target locale is available, both the core interpreter and
- locale-aware C extensions will assume the use of UTF-8 as the default text
- encoding, rather than ASCII.
-
-- bpo-30486: Allows setting cell values for __closure__. Patch by Lisa Roach.
-
-- bpo-30537: itertools.islice now accepts integer-like objects (having
- an __index__ method) as start, stop, and slice arguments
-
-- bpo-25324: Tokens needed for parsing in Python moved to C. ``COMMENT``,
- ``NL`` and ``ENCODING``. This way the tokens and tok_names in the token
- module don't get changed when you import the tokenize module.
-
-- bpo-29104: Fixed parsing backslashes in f-strings.
-
-- bpo-27945: Fixed various segfaults with dict when input collections are
- mutated during searching, inserting or comparing. Based on patches by
- Duane Griffin and Tim Mitchell.
-
-- bpo-25794: Fixed type.__setattr__() and type.__delattr__() for
- non-interned attribute names. Based on patch by Eryk Sun.
-
-- bpo-30039: If a KeyboardInterrupt happens when the interpreter is in
- the middle of resuming a chain of nested 'yield from' or 'await'
- calls, it's now correctly delivered to the innermost frame.
-
-- bpo-28974: ``object.__format__(x, '')`` is now equivalent to ``str(x)``
- rather than ``format(str(self), '')``.
-
-- bpo-30024: Circular imports involving absolute imports with binding
- a submodule to a name are now supported.
-
-- bpo-12414: sys.getsizeof() on a code object now returns the sizes
- which includes the code struct and sizes of objects which it references.
- Patch by Dong-hee Na.
-
-- bpo-29839: len() now raises ValueError rather than OverflowError if
- __len__() returned a large negative integer.
-
-- bpo-11913: README.rst is now included in the list of distutils standard
- READMEs and therefore included in source distributions.
-
-- bpo-29914: Fixed default implementations of __reduce__ and __reduce_ex__().
- object.__reduce__() no longer takes arguments, object.__reduce_ex__() now
- requires one argument.
-
-- bpo-29949: Fix memory usage regression of set and frozenset object.
-
-- bpo-29935: Fixed error messages in the index() method of tuple, list and deque
- when pass indices of wrong type.
-
-- bpo-29816: Shift operation now has less opportunity to raise OverflowError.
- ValueError always is raised rather than OverflowError for negative counts.
- Shifting zero with non-negative count always returns zero.
-
-- bpo-24821: Fixed the slowing down to 25 times in the searching of some
- unlucky Unicode characters.
-
-- bpo-29102: Add a unique ID to PyInterpreterState. This makes it easier
- to identify each subinterpreter.
-
-- bpo-29894: The deprecation warning is emitted if __complex__ returns an
- instance of a strict subclass of complex. In a future versions of Python
- this can be an error.
-
-- bpo-29859: Show correct error messages when any of the pthread_* calls in
- thread_pthread.h fails.
-
-- bpo-29849: Fix a memory leak when an ImportError is raised during from import.
-
-- bpo-28856: Fix an oversight that %b format for bytes should support objects
- follow the buffer protocol.
-
-- bpo-29723: The ``sys.path[0]`` initialization change for bpo-29139 caused a
- regression by revealing an inconsistency in how sys.path is initialized when
- executing ``__main__`` from a zipfile, directory, or other import location.
- The interpreter now consistently avoids ever adding the import location's
- parent directory to ``sys.path``, and ensures no other ``sys.path`` entries
- are inadvertently modified when inserting the import location named on the
- command line.
-
-- bpo-29568: Escaped percent "%%" in the format string for classic string
- formatting no longer allows any characters between two percents.
-
-- bpo-29714: Fix a regression that bytes format may fail when containing zero
- bytes inside.

- returned from __aiter__ and __anext__.
-
-- bpo-28876: ``bool(range)`` works even if ``len(range)``
- raises :exc:`OverflowError`.
-
-- bpo-29683: Fixes to memory allocation in _PyCode_SetExtra. Patch by
- Brian Coleman.
-
-- bpo-29684: Fix minor regression of PyEval_CallObjectWithKeywords.
- It should raise TypeError when kwargs is not a dict. But it might
- cause segv when args=NULL and kwargs is not a dict.
-
-- bpo-28598: Support __rmod__ for subclasses of str being called before
- str.__mod__. Patch by Martijn Pieters.
-
-- bpo-29607: Fix stack_effect computation for CALL_FUNCTION_EX.
- Patch by Matthieu Dartiailh.

-
-- bpo-29347: Fixed possibly dereferencing undefined pointers
- when creating weakref objects.
-
-- bpo-29463: Add ``docstring`` field to Module, ClassDef, FunctionDef,
- and AsyncFunctionDef ast nodes. docstring is not first stmt in their body
- anymore. It affects ``co_firstlineno`` and ``co_lnotab`` of code object
- for module and class.
-
-- bpo-29438: Fixed use-after-free problem in key sharing dict.
-
-- bpo-29546: Set the 'path' and 'name' attribute on ImportError for ``from ... import ...``.

- allocators in your application.
-
-- Issue #26802: Optimize function calls only using unpacking like

-
-- Issue #22836: Ensure exception reports from PyErr_Display() and
- PyErr_WriteUnraisable() are sensible even when formatting them produces

- (``int``) and ``f2()`` returns ``1.0`` (``float``), even if ``1`` and ``1.0``
- are equal.
-
-- Issue #26107: The format of the ``co_lnotab`` attribute of code objects
- changes to support negative line number delta.
-
-- Issue #26154: Add a new private _PyThreadState_UncheckedGet() function to get
- the current Python thread state, but don't issue a fatal error if it is NULL.

- when compiling AST from Python objects.
-

-
-- Issue #24455: Prevent IDLE from hanging when a) closing the shell while the

- such as 'Custom Dark'. The custom theme will work with any IDLE
- release, and can be modified.

- instead relying on OpenSSL source being configured and ready to build. The
- ``PCbuild\build_ssl.py`` script has been re-written and re-named to
- ``PCbuild\prepare_ssl.py``, and takes care of configuring OpenSSL source
- for both 32 and 64 bit platforms. OpenSSL sources obtained from
- svn.python.org will always be pre-configured and ready to build.
-
-- Issue #21037: Add a build option to enable AddressSanitizer support.
-
-- Issue #19962: The Windows build process now creates "python.bat" in the
- root of the source tree, which passes all arguments through to the most
- recently built interpreter.
-
-- Issue #21285: Refactor and fix curses configure check to always search
- in a ncursesw directory.
-
-- Issue #15234: For BerkelyDB and Sqlite, only add the found library and
- include directories if they aren't already being searched. This avoids
- an explicit runtime library dependency.
-
-- Issue #17861: Tools/scripts/generate_opcode_h.py automatically regenerates
- Include/opcode.h from Lib/opcode.py if the latter gets any change.
-

-C API
------
-
-- Issue #14203: Remove obsolete support for view==NULL in PyBuffer_FillInfo(),
- bytearray_getbuffer(), bytesiobuf_getbuffer() and array_buffer_getbuf().
- All functions now raise BufferError in that case.
-
-- Issue #22445: PyBuffer_IsContiguous() now implements precise contiguity
- tests, compatible with NumPy's NPY_RELAXED_STRIDES_CHECKING compilation
- flag. Previously the function reported false negatives for corner cases.
-
-- Issue #22079: PyType_Ready() now checks that statically allocated type has
- no dynamically allocated bases.
-
-- Issue #22453: Removed non-documented macro PyObject_REPR().
-
-- Issue #18395: Rename ``_Py_char2wchar()`` to :c:func:`Py_DecodeLocale`,
- rename ``_Py_wchar2char()`` to :c:func:`Py_EncodeLocale`, and document
- these functions.
-
-- Issue #21233: Add new C functions: PyMem_RawCalloc(), PyMem_Calloc(),
- PyObject_Calloc(), _PyObject_GC_Calloc(). bytes(int) is now using
- ``calloc()`` instead of ``malloc()`` for large objects which is faster and
- use less memory.
-
-- Issue #20942: PyImport_ImportFrozenModuleObject() no longer sets __file__ to
- match what importlib does; this affects _frozen_importlib as well as any
- module loaded using imp.init_frozen().
-
-Documentation
--------------

-- Issue #19548: Update the codecs module documentation to better cover the
- distinction between text encodings and other codecs, together with other
- clarifications. Patch by Martin Panter.

-
-- Issue #19407: New package installation and distribution guides based on

- as legacy links from the distutils docs, as they still contain some
- required reference material for tool developers that isn't recorded
- anywhere else.
-
-- Issue #19697: Document cases where __main__.__spec__ is None.
