+- Forbid summing bytes with sum().
+
+- Verify the types of AST strings and identifiers provided by the user before
+ compiling them.
+
+- Issue #12647: The None object now has a __bool__() method that returns False.
+ Formerly, bool(None) returned False only because of special case logic
+ in PyObject_IsTrue().
+
+- Issue #12579: str.format_map() now raises a ValueError if used on a
+ format string that contains positional fields. Initial patch by
+ Julian Berman.
+
+- Issue #10271: Allow warnings.showwarning() be any callable.

+- Issue #11627: Fix segfault when __new__ on a exception returns a
+ non-exception class.
+
++- Issue #12149: Update the method cache after a type's dictionary gets
+ cleared by the garbage collector. This fixes a segfault when an instance
+ and its type get caught in a reference cycle, and the instance's
+ deallocator calls one of the methods on the type (e.g. when subclassing
+ IOBase). Diagnosis and patch by Davide Rizzo.
+

+ a new HAVE_MBCS define.
+
+- Issue #9642: Fix filesystem encoding initialization: use the ANSI code page
+ on Windows if the mbcs codec is not available, and fail with a fatal error if
+ we cannot get the locale encoding (if nl_langinfo(CODESET) is not available)
+ instead of using UTF-8.
+
+- When a generator yields, do not retain the caller's exception state on the
+ generator.
+
+- Issue #12475: Prevent generators from leaking their exception state into the
+ caller's frame as they return for the last time.
+

+ missing arguments.
+
+- Issue #12370: Fix super with not arguments when __class__ is overriden in the
+ class body.
+
+- Issue #12084: os.stat on Windows now works properly with relative symbolic
+ links when called from any directory.
+
+- Loosen type restrictions on the __dir__ method. __dir__ can now return any

+
+- Issue #12265: Make error messages produced by passing an invalid set of
+ arguments to a function more informative.
+
+- Issue #12225: Still allow Python to build if Python is not in its hg repo or
+ mercurial is not installed.
+
+- Issue #1195: my_fgets() now always clears errors before calling fgets(). Fix

+
+- Issue #12199: The TryExcept and TryFinally and AST nodes have been unified
+ into a Try node.
+
+- Issue #9670: Increase the default stack size for secondary threads on
+ Mac OS X and FreeBSD to reduce the chances of a crash instead of a
+ "maximum recursion depth" RuntimeError exception.

+ the __dir__() methods of those types.
+
+- Issue #5715: In socketserver, close the server socket in the child process.
+
+- Correct lookup of __dir__ on objects. Among other things, this causes errors
+ besides AttributeError found on lookup to be propagated.
+
+- Issue #12060: Use sig_atomic_t type and volatile keyword in the signal
+ module. Patch written by Charles-François Natali.
+
+- Issue #1746656: Added the if_nameindex, if_indextoname, if_nametoindex
+ methods to the socket module.
+
+- Issue #12044: Fixed subprocess.Popen when used as a context manager to

+ free()d memory arenas on glibc-based systems. Patch by Charles-François
+ Natali.
+
+- Issue #9756: When calling a method descriptor or a slot wrapper descriptor,
+ the check of the object type doesn't read the __class__ attribute anymore.
+ Fix a crash if a class override its __class__ attribute (e.g. a proxy of the

+ maintainer.
+
+- Issue #6780: fix starts/endswith error message to mention that tuples are
+ accepted too.
+
+- Issue #5057: fix a bug in the peepholer that led to non-portable pyc files
+ between narrow and wide builds while optimizing BINARY_SUBSCR on non-BMP
+ chars (e.g. "\U00012345"[0]).
+
+- Issue #11845: Fix typo in rangeobject.c that caused a crash in
+ compute_slice_indices. Patch by Daniel Urban.
+
+- Issue #5673: Added a `timeout` keyword argument to subprocess.Popen.wait,
+ subprocess.Popen.communicated, subprocess.call, subprocess.check_call, and
+ subprocess.check_output. If the blocking operation takes more than `timeout`
+ seconds, the `subprocess.TimeoutExpired` exception is raised.
+
+- Issue #11650: PyOS_StdioReadline() retries fgets() if it was interrupted
+ (EINTR), for example if the program is stopped with CTRL+z on Mac OS X. Patch
+ written by Charles-Francois Natali.

+
+- Issue #10785: Store the filename as Unicode in the Python parser.
+
+- Issue #11619: _PyImport_LoadDynamicModule() doesn't encode the path to bytes
+ on Windows.
+
+- Issue #10998: Remove mentions of -Q, sys.flags.division_warning and
+ Py_DivisionWarningFlag left over from Python 2.
+
+- Issue #11244: Remove an unnecessary peepholer check that was preventing
+ negative zeros from being constant-folded properly.
+
+- Issue #11395: io.FileIO().write() clamps the data length to 32,767 bytes on
+ Windows if the file is a TTY to workaround a Windows bug. The Windows console
+ returns an error (12: not enough space error) on writing into stdout if
+ stdout mode is binary and the length is greater than 66,000 bytes (or less,
+ depending on heap usage).
+
+- Issue #11320: fix bogus memory management in Modules/getpath.c, leading to
+ a possible crash when calling Py_SetPath().
+
+- _ast.__version__ is now a Mercurial hex revision.
+
+- Issue #11432: A bug was introduced in subprocess.Popen on posix systems with
+ 3.2.0 where the stdout or stderr file descriptor being the same as the stdin
+ file descriptor would raise an exception. webbrowser.open would fail. fixed.
+
+- Issue #9856: Change object.__format__ with a non-empty format string
+ to be a DeprecationWarning. In 3.2 it was a PendingDeprecationWarning.
+ In 3.4 it will be a TypeError.
+
+- Issue #11244: The peephole optimizer is now able to constant-fold
+ arbitrarily complex expressions. This also fixes a 3.2 regression where
+ operations involving negative numbers were not constant-folded.
+
+- Issue #11450: Don't truncate hg version info in Py_GetBuildInfo() when
+ there are many tags (e.g. when using mq). Patch by Nadeem Vawda.
+
+- Issue #11335: Fixed a memory leak in list.sort when the key function
+ throws an exception.
+
+- Issue #8923: When a string is encoded to UTF-8 in strict mode, the result is
+ cached into the object. Examples: str.encode(), str.encode('utf-8'),
+ PyUnicode_AsUTF8String() and PyUnicode_AsEncodedString(unicode, "utf-8",
+ NULL).
+
+- Issue #10831: PyUnicode_FromFormat() supports %li, %lli and %zi formats.
+
+- Issue #10829: Refactor PyUnicode_FromFormat(), use the same function to parse
+ the format string in the 3 steps, fix crashs on invalid format strings.
+
+- Issue #11246: Fix PyUnicode_FromFormat("%V") to decode the byte string from
+ UTF-8 (with replace error handler) instead of ISO-8859-1 (in strict mode).
+ Patch written by Ray Allen.
+
+- Issue #11286: Raise a ValueError from calling PyMemoryView_FromBuffer with
+ a buffer struct having a NULL data pointer.
+
+- Issue #11272: On Windows, input() strips '\r' (and not only '\n'), and
+ sys.stdin uses universal newline (replace '\r\n' by '\n').
+
+- issue #11828: startswith and endswith don't accept None as slice index.
+ Patch by Torsten Becker.
+
+- Issue #10830: Fix PyUnicode_FromFormatV("%c") for non-BMP characters on
+ narrow build.
+
+- Issue #11168: Remove filename debug variable from PyEval_EvalFrameEx().
+ It encoded the Unicode filename to UTF-8, but the encoding fails on
+ undecodable filename (on surrogate characters) which raises an unexpected
+ UnicodeEncodeError on recursion limit.
+
+- Issue #11187: Remove bootstrap code (use ASCII) of
+ PyUnicode_AsEncodedString(), it was replaced by a better fallback (use the
+ locale encoding) in PyUnicode_EncodeFSDefault().
+
+- Check for NULL result in PyType_FromSpec.
+
+- Issue #10516: New copy() and clear() methods for lists and bytearrays.
+
+- Issue #11386: bytearray.pop() now throws IndexError when the bytearray is
+ empty, instead of OverflowError.
+
+- Issue #12380: The rjust, ljust and center methods of bytes and bytearray
+ now accept a bytearray argument.
