+****************************
+  What's New In Python 3.7
+****************************
+
+:Release: |release|
+:Date: |today|
+
+.. Rules for maintenance:
+
+   * Anyone can add text to this document.  Do not spend very much time
+   on the wording of your changes, because your text will probably
+   get rewritten to some degree.
+
+   * The maintainer will go through Misc/NEWS periodically and add
+   changes; it's therefore more important to add your changes to
+   Misc/NEWS than to this file.
+
+   * This is not a complete list of every single change; completeness
+   is the purpose of Misc/NEWS.  Some changes I consider too small
+   or esoteric to include.  If such a change is added to the text,
+   I'll just remove it.  (This is another reason you shouldn't spend
+   too much time on writing your addition.)
+
+   * If you want to draw your new text to the attention of the
+   maintainer, add 'XXX' to the beginning of the paragraph or
+   section.
+
+   * It's OK to just add a fragmentary note about a change.  For
+   example: "XXX Describe the transmogrify() function added to the
+   socket module."  The maintainer will research the change and
+   write the necessary text.
+
+   * You can comment out your additions if you like, but it's not
+   necessary (especially when a final release is some months away).
+
+   * Credit the author of a patch or bugfix.   Just the name is
+   sufficient; the e-mail address isn't necessary.
+
+   * It's helpful to add the bug/patch number as a comment:
+
+   XXX Describe the transmogrify() function added to the socket
+   module.
+   (Contributed by P.Y. Developer in :issue:`12345`.)
+
+   This saves the maintainer the effort of going through the Mercurial log
+   when researching a change.
+
+This article explains the new features in Python 3.7, compared to 3.6.
+
+For full details, see the :source:`Misc/NEWS` file.
+
+.. note::
+
+   Prerelease users should be aware that this document is currently in draft
+   form. It will be updated substantially as Python 3.7 moves towards release,
+   so it's worth checking back even after reading earlier versions.
+

+  BaseEventLoop.set_debug() and BaseEventLoop.get_debug().
+  Add support for setting 'asyncio.tasks._DEBUG' variable with
+  'PYTHONASYNCIODEBUG' environment variable.
+
+- asyncio: Refactoring and fixes: BaseEventLoop.sock_connect() raises an
+  error if the address is not resolved; use __slots__ in Handle and
+  TimerHandle; as_completed() and wait() raise TypeError if the passed
+  list of Futures is a single Future; call_soon() and other 'call_*()'
+  functions raise TypeError if the passed callback is a coroutine
+  function; _ProactorBasePipeTransport uses _FlowControlMixin;

+
+- Issue #20616: Add a format() method to tracemalloc.Traceback.
+
+- Issue #19744: the ensurepip installation step now just prints a warning to

+
+Build
+-----

+
+
+What's New in Python 3.4.0 release candidate 1?
+===============================================
+
+Release date: 2014-02-10
+
+Core and Builtins
+-----------------
+
+- Issue #19255: The builtins module is restored to initial value before
+  cleaning other modules.  The sys and builtins modules are cleaned last.
+
+- Issue #20588: Make Python-ast.c C89 compliant.
+
+- Issue #20437: Fixed 22 potential bugs when deleting object references.
+
+- Issue #20500: Displaying an exception at interpreter shutdown no longer
+  risks triggering an assertion failure in PyObject_Str.
+
+- Issue #20538: UTF-7 incremental decoder produced inconsistent string when
+  input was truncated in BASE64 section.
+
+- Issue #20404: io.TextIOWrapper (and hence the open() builtin) now uses the
+  internal codec marking system added for issue #19619 to throw LookupError
+  for known non-text encodings at stream construction time. The existing
+  output type checks remain in place to deal with unmarked third party
+  codecs.
+
+- Issue #17162: Add PyType_GetSlot.
+
+- Issue #20162: Fix an alignment issue in the siphash24() hash function which
+  caused a crash on PowerPC 64-bit (ppc64).
+
+Library
+-------
+
+- Issue #20530: The signatures for slot builtins have been updated
+  to reflect the fact that they only accept positional-only arguments.
+
+- Issue #20517: Functions in the os module that accept two filenames
+  now register both filenames in the exception on failure.
+
+- Issue #20563: The ipaddress module API is now considered stable.
+
+- Issue #14983: email.generator now always adds a line end after each MIME
+  boundary marker, instead of doing so only when there is an epilogue.  This
+  fixes an RFC compliance bug and solves an issue with signed MIME parts.
+
+- Issue #20540: Fix a performance regression (vs. Python 3.2) when layering
+  a multiprocessing Connection over a TCP socket.  For small payloads, Nagle's
+  algorithm would introduce idle delays before the entire transmission of a
+  message.
+
+- Issue #16983: the new email header parsing code will now decode encoded words
+  that are (incorrectly) surrounded by quotes, and register a defect.
+
+- Issue #19772: email.generator no longer mutates the message object when
+  doing a down-transform from 8bit to 7bit CTEs.
+
+- Issue #20536: the statistics module now correctly handle Decimal instances
+  with positive exponents
+
+- Issue #18805: the netmask/hostmask parsing in ipaddress now more reliably
+  filters out illegal values and correctly allows any valid prefix length.
+
+- Issue #20481: For at least Python 3.4, the statistics module will require
+  that all inputs for a single operation be of a single consistent type, or
+  else a mixed of ints and a single other consistent type. This avoids
+  some interoperability issues that arose with the previous approach of
+  coercing to a suitable common type.
+
+- Issue #20478: the statistics module now treats collections.Counter inputs
+  like any other iterable.
+
+- Issue #17369: get_filename was raising an exception if the filename
+  parameter's RFC2231 encoding was broken in certain ways.  This was
+  a regression relative to python2.
+
+- Issue #20013: Some imap servers disconnect if the current mailbox is
+  deleted, and imaplib did not handle that case gracefully.  Now it
+  handles the 'bye' correctly.
+
+- Issue #20531: Revert 3.4 version of fix for #19063, and apply the 3.3
+  version.  That is, do *not* raise an error if unicode is passed to
+  email.message.Message.set_payload.
+
+- Issue #20476: If a non-compat32 policy is used with any of the email parsers,
+  EmailMessage is now used as the factory class.  The factory class should
+  really come from the policy; that will get fixed in 3.5.
+
+- Issue #19920: TarFile.list() no longer fails when outputs a listing
+  containing non-encodable characters.  Based on patch by Vajrasky Kok.
+
+- Issue #20515: Fix NULL pointer dereference introduced by issue #20368.
+
+- Issue #19186: Restore namespacing of expat symbols inside the pyexpat module.
+
+- Issue #20053: ensurepip (and hence venv) are no longer affected by the
+  settings in the default pip configuration file.
+
+- Issue #20426: When passing the re.DEBUG flag, re.compile() displays the
+  debug output every time it is called, regardless of the compilation cache.
+
+- Issue #20368: The null character now correctly passed from Tcl to Python.
+  Improved error handling in variables-related commands.
+
+- Issue #20435: Fix _pyio.StringIO.getvalue() to take into account newline
+  translation settings.
+
+- tracemalloc: Fix slicing traces and fix slicing a traceback.
+
+- Issue #20354: Fix an alignment issue in the tracemalloc module on 64-bit
+  platforms. Bug seen on 64-bit Linux when using "make profile-opt".
+
+- Issue #17159: inspect.signature now accepts duck types of functions,
+  which adds support for Cython functions. Initial patch by Stefan Behnel.
+
+- Issue #18801: Fix inspect.classify_class_attrs to correctly classify
+  object.__new__ and object.__init__.
+
+- Fixed cmath.isinf's name in its argument parsing code.
+
+- Issue #20311, #20452: poll and epoll now round the timeout away from zero,
+  instead of rounding towards zero, in select and selectors modules:
+  select.epoll.poll(), selectors.PollSelector.poll() and
+  selectors.EpollSelector.poll(). For example, a timeout of one microsecond
+  (1e-6) is now rounded to one millisecondi (1e-3), instead of being rounded to
+  zero.  However, the granularity property and asyncio's resolution feature
+  were removed again.
+
+- asyncio: Some refactoring; various fixes; add write flow control to
+  unix pipes; Future.set_exception() instantiates the exception
+  argument if it is a class; improved proactor pipe transport; support
+  wait_for(f, None); don't log broken/disconnected pipes; use
+  ValueError instead of assert for forbidden subprocess_{shell,exec}
+  arguments; added a convenience API for subprocess management; added
+  StreamReader.at_eof(); properly handle duplicate coroutines/futures
+  in gather(), wait(), as_completed(); use a bytearray for buffering
+  in StreamReader; and more.
+
+- Issue #20288: fix handling of invalid numeric charrefs in HTMLParser.
+
+- Issue #20424: Python implementation of io.StringIO now supports lone surrogates.
+
+- Issue #20308: inspect.signature now works on classes without user-defined
+  __init__ or __new__ methods.
+
+- Issue #20372: inspect.getfile (and a bunch of other inspect functions that
+  use it) doesn't crash with unexpected AttributeError on classes defined in C
+  without __module__.
+
+- Issue #20356: inspect.signature formatting uses '/' to separate
+  positional-only parameters from others.
+
+- Issue #20223: inspect.signature now supports methods defined with
+  functools.partialmethods.
+
+- Issue #19456: ntpath.join() now joins relative paths correctly when a drive
+  is present.
+
+- Issue #19077: tempfile.TemporaryDirectory cleanup no longer fails when
+  called during shutdown.  Emitting resource warning in __del__ no longer fails.
+  Original patch by Antoine Pitrou.
+
+- Issue #20394: Silence Coverity warning in audioop module.
+
+- Issue #20367: Fix behavior of concurrent.futures.as_completed() for
+  duplicate arguments.  Patch by Glenn Langford.
+
+- Issue #8260: The read(), readline() and readlines() methods of
+  codecs.StreamReader returned incomplete data when were called after
+  readline() or read(size).  Based on patch by Amaury Forgeot d'Arc.
+
+- Issue #20105: the codec exception chaining now correctly sets the
+  traceback of the original exception as its __traceback__ attribute.
+
+- Issue #17481: inspect.getfullargspec() now uses inspect.signature() API.
+
+- Issue #15304: concurrent.futures.wait() can block forever even if
+  Futures have completed. Patch by Glenn Langford.
+
+- Issue #14455: plistlib: fix serializing integers in the range
+  of an unsigned long long but outside of the range of signed long long for
+  binary plist files.
+
+IDLE
+----
+
+- Issue #20406: Use Python application icons for Idle window title bars.
+  Patch mostly by Serhiy Storchaka.
+
+- Update the python.gif icon for the Idle classbrowser and pathbowser
+  from the old green snake to the new blue and yellow snakes.
+
+- Issue #17721: Remove non-functional configuration dialog help button until we
+  make it actually gives some help when clicked. Patch by Guilherme Simões.
+
+Tests
+-----
+
+- Issue #20532: Tests which use _testcapi now are marked as CPython only.
+
+- Issue #19920: Added tests for TarFile.list().  Based on patch by Vajrasky Kok.
+
+- Issue #19990: Added tests for the imghdr module.  Based on patch by
+  Claudiu Popa.
+
+- Issue #20474: Fix test_socket "unexpected success" failures on OS X 10.7+.
+
+Tools/Demos
+-----------
+
+- Issue #20530: Argument Clinic's signature format has been revised again.
+  The new syntax is highly human readable while still preventing false
+  positives.  The syntax also extends Python syntax to denote "self" and
+  positional-only parameters, allowing inspect.Signature objects to be
+  totally accurate for all supported builtins in Python 3.4.
+
+- Issue #20456: Argument Clinic now observes the C preprocessor conditional
+  compilation statements of the C files it parses.  When a Clinic block is
+  inside a conditional code, it adjusts its output to match, including
+  automatically generating an empty methoddef macro.
+
+- Issue #20456: Cloned functions in Argument Clinic now use the correct
+  name, not the name of the function they were cloned from, for text
+  strings inside generated code.
+
+- Issue #20456: Fixed Argument Clinic's test suite and "--converters" feature.
+
+- Issue #20456: Argument Clinic now allows specifying different names
+  for a parameter in Python and C, using "as" on the parameter line.
+
+- Issue #20326: Argument Clinic now uses a simple, unique signature to
+  annotate text signatures in docstrings, resulting in fewer false
+  positives.  "self" parameters are also explicitly marked, allowing
+  inspect.Signature() to authoritatively detect (and skip) said parameters.
+
+- Issue #20326: Argument Clinic now generates separate checksums for the
+  input and output sections of the block, allowing external tools to verify
+  that the input has not changed (and thus the output is not out-of-date).
+
+Build
+-----
+
+- Issue #20465: Update SQLite shipped with OS X installer to 3.8.3.
+
+C-API
+-----
+
+- Issue #20517: Added new functions allowing OSError exceptions to reference
+  two filenames instead of one: PyErr_SetFromErrnoWithFilenameObjects() and
+  PyErr_SetExcFromWindowsErrWithFilenameObjects().
+
+Documentation
+-------------
+
+- Issue #20488: Change wording to say importlib is *the* implementation of
+  import instead of just *an* implementation.
+
+- Issue #6386: Clarify in the tutorial that specifying a symlink to execute
+  means the directory containing the executed script and not the symlink is
+  added to sys.path.
+
+
+What's New in Python 3.4.0 Beta 3?
+==================================
+
+Release date: 2014-01-26
+
+Core and Builtins
+-----------------
+
+- Issue #20189: Four additional builtin types (PyTypeObject,
+  PyMethodDescr_Type, _PyMethodWrapper_Type, and PyWrapperDescr_Type)
+  have been modified to provide introspection information for builtins.
+
+- Issue #17825: Cursor "^" is correctly positioned for SyntaxError and
+  IndentationError.
+
+- Issue #2382: SyntaxError cursor "^" is now written at correct position in most
+  cases when multibyte characters are in line (before "^").  This still not
+  works correctly with wide East Asian characters.
+
+- Issue #18960: The first line of Python script could be executed twice when
+  the source encoding was specified on the second line.  Now the source encoding
+  declaration on the second line isn't effective if the first line contains
+  anything except a comment.  'python -x' works now again with files with the
+  source encoding declarations, and can be used to make Python batch files
+  on Windows.
+
+Library
+-------
+
+- asyncio: Various improvements and small changes not all covered by
+  issues listed below.  E.g. wait_for() now cancels the inner task if
+  the timeout occcurs; tweaked the set of exported symbols; renamed
+  Empty/Full to QueueEmpty/QueueFull; "with (yield from lock)" now
+  uses a separate context manager; readexactly() raises if not enough
+  data was read; PTY support tweaks.
+
+- Issue #20311: asyncio: Add a granularity attribute to BaseEventLoop: maximum
+  between the resolution of the BaseEventLoop.time() method and the resolution
+  of the selector. The granuarility is used in the scheduler to round time and
+  deadline.
+
+- Issue #20311: selectors: Add a resolution attribute to BaseSelector.
+
+- Issue #20189: unittest.mock now no longer assumes that any object for
+  which it could get an inspect.Signature is a callable written in Python.
+  Fix courtesy of Michael Foord.
+
+- Issue #20317: ExitStack.__exit__ could create a self-referential loop if an
+  exception raised by a cleanup operation already had its context set
+  correctly (for example, by the @contextmanager decorator). The infinite
+  loop this caused is now avoided by checking if the expected context is
+  already set before trying to fix it.
+

+
+What's New in Python 3.4.0 Beta 2?
+==================================
+
+Release date: 2014-01-05
+
+Core and Builtins
+-----------------
+
+- Issue #17432: Drop UCS2 from names of Unicode functions in python3.def.
+
+- Issue #19526: Exclude all new API from the stable ABI. Exceptions can be
+  made if a need is demonstrated.
+
+- Issue #19969: PyBytes_FromFormatV() now raises an OverflowError if "%c"
+  argument is not in range [0; 255].
+
+- Issue #19995: %c, %o, %x, and %X now issue a DeprecationWarning on non-integer
+  input; reworded docs to clarify that an integer type should define both __int__
+  and __index__.
+
+- Issue #19787: PyThread_set_key_value() now always set the value. In Python
+  3.3, the function did nothing if the key already exists (if the current value
+  is a non-NULL pointer).
+
+- Issue #14432: Remove the thread state field from the frame structure. Fix a
+  crash when a generator is created in a C thread that is destroyed while the
+  generator is still used. The issue was that a generator contains a frame, and
+  the frame kept a reference to the Python state of the destroyed C thread. The
+  crash occurs when a trace function is setup.
+
+- Issue #19576: PyGILState_Ensure() now initializes threads. At startup, Python
+  has no concrete GIL. If PyGILState_Ensure() is called from a new thread for
+  the first time and PyEval_InitThreads() was not called yet, a GIL needs to be
+  created.
+
+- Issue #17576: Deprecation warning emitted now when __int__() or __index__()
+  return not int instance.
+
+- Issue #19932: Fix typo in import.h, missing whitespaces in function prototypes.
+
+- Issue #19736: Add module-level statvfs constants defined for GNU/glibc
+  based systems.
+
+- Issue #20097: Fix bad use of "self" in importlib's WindowsRegistryFinder.
+
+- Issue #19729: In str.format(), fix recursive expansion in format spec.
+
+- Issue #19638: Fix possible crash / undefined behaviour from huge (more than 2
+  billion characters) input strings in _Py_dg_strtod.
+
+Library

+
+- Fix breakage in TestSuite.countTestCases() introduced by issue #11798.
+
+- Issue #20108: Avoid parameter name clash in inspect.getcallargs().
+
+- Issue #19918: Fix PurePath.relative_to() under Windows.
+
+- Issue #19422: Explicitly disallow non-SOCK_STREAM sockets in the ssl
+  module, rather than silently let them emit clear text data.
+
+- Issue #20046: Locale alias table no longer contains entities which can be
+  calculated.  Generalized support of the euro modifier.
+
+- Issue #20027: Fixed locale aliases for devanagari locales.
+
+- Issue #20067: Tkinter variables now work when wantobjects is false.
+
+- Issue #19020: Tkinter now uses splitlist() instead of split() in configure
+  methods.
+
+- Issue #19744: ensurepip now provides a better error message when Python is
+  built without SSL/TLS support (pip currently requires that support to run,
+  even if only operating with local wheel files)
+
+- Issue #19734: ensurepip now ignores all pip environment variables to avoid
+  odd behaviour based on user configuration settings
+
+- Fix TypeError on "setup.py upload --show-response".
+
+- Issue #20045: Fix "setup.py register --list-classifiers".
+
+- Issue #18879: When a method is looked up on a temporary file, avoid closing
+  the file before the method is possibly called.
+
+- Issue #20037: Avoid crashes when opening a text file late at interpreter
+  shutdown.
+
+- Issue #19967: Thanks to the PEP 442, asyncio.Future now uses a
+  destructor to log uncaught exceptions, instead of the dedicated
+  _TracebackLogger class.
+
+- Added a Task.current_task() class method to asyncio.
+
+- Issue #19850: Set SA_RESTART in asyncio when registering a signal
+  handler to limit EINTR occurrences.
+
+- Implemented write flow control in asyncio for proactor event loop (Windows).
+
+- Change write buffer in asyncio use to avoid O(N**2) behavior.  Make
+  write()/sendto() accept bytearray/memoryview.
+
+- Issue #20034: Updated alias mapping to most recent locale.alias file
+  from X.org distribution using makelocalealias.py.
+

+- Issue #20026: Fix the sqlite module to handle correctly invalid isolation
+  level (wrong type).

+  executables used to find the mac address, with /sbin and /usr/sbin as
+  fallbacks.
+
+- Issue #20007: HTTPResponse.read(0) no more prematurely closes connection.
+  Original patch by Simon Sapin.
+
+- Issue #19946: multiprocessing now uses runpy to initialize __main__ in
+  child processes when necessary, allowing it to correctly handle scripts
+  without suffixes and submodules that use explicit relative imports or
+  otherwise rely on parent modules being correctly imported prior to
+  execution.
+
+- Issue #19921: When Path.mkdir() is called with parents=True, any missing
+  parent is created with the default permissions, ignoring the mode argument
+  (mimicking the POSIX "mkdir -p" command).
+
+- Issue #19887: Improve the Path.resolve() algorithm to support certain
+  symlink chains.
+
+- Issue #19912: Fixed numerous bugs in ntpath.splitunc().
+
+- Issue #19911: ntpath.splitdrive() now correctly processes the 'İ' character
+  (U+0130, LATIN CAPITAL LETTER I WITH DOT ABOVE).
+
+- Issue #19532: python -m compileall with no filename/directory arguments now
+  respects the -f and -q flags instead of ignoring them.
+
+- Issue #19623: Fixed writing to unseekable files in the aifc module.
+
+- Issue #19946: multiprocessing.spawn now raises ImportError when the module to
+  be used as the main module cannot be imported.
+
+- Issue #17919: select.poll.register() again works with poll.POLLNVAL on AIX.
+  Fixed integer overflow in the eventmask parameter.
+
+- Issue #19063: if a Charset's body_encoding was set to None, the email
+  package would generate a message claiming the Content-Transfer-Encoding
+  was 7bit, and produce garbage output for the content.  This now works.
+  A couple of other set_payload mishandlings of non-ASCII are also fixed.
+  In addition, calling set_payload with a string argument without
+  specifying a charset now raises an error (this is a new error in 3.4).
+
+- Issue #15475: Add __sizeof__ implementations for itertools objects.
+
+- Issue #19944: Fix importlib.find_spec() so it imports parents as needed
+  and move the function to importlib.util.
+
+- Issue #19880: Fix a reference leak in unittest.TestCase. Explicitly break
+  reference cycles between frames and the _Outcome instance.
+
+- Issue #17429: platform.linux_distribution() now decodes files from the UTF-8
+  encoding with the surrogateescape error handler, instead of decoding from the
+  locale encoding in strict mode. It fixes the function on Fedora 19 which is
+  probably the first major distribution release with a non-ASCII name. Patch
+  written by Toshio Kuratomi.
+
+- Issue #19343: Expose FreeBSD-specific APIs in resource module.  Original
+  patch by Koobs.
+
+- Issue #19929: Call os.read with 32768 within subprocess.Popen.communicate
+  rather than 4096 for efficiency.  A microbenchmark shows Linux and OS X
+  both using ~50% less cpu time this way.
+
+- Issue #19506: Use a memoryview to avoid a data copy when piping data
+  to stdin within subprocess.Popen.communicate.  5-10% less cpu usage.

+  EOF, and analogous bug in lzma module.
+
+- Issue #19881: Fix pickling bug where cpickle would emit bad pickle data for
+  large bytes string (i.e., with size greater than 2**32-1).
+
+- Issue #19138: doctest's IGNORE_EXCEPTION_DETAIL now allows a match when
+  no exception detail exists (no colon following the exception's name, or
+  a colon does follow but no text follows the colon).
+
+- Issue #19927: Add __eq__ to path-based loaders in importlib.
+
+- Issue #19827: On UNIX, setblocking() and settimeout() methods of
+  socket.socket can now avoid a second syscall if the ioctl() function can be

+  indication for TLS/SSL connections.

+
+What's New in Python 3.4.0 Beta 1?
+==================================
+
+Release date: 2013-11-24
+
+Core and Builtins
+-----------------
+
+- Use the repr of a module name in more places in import, especially
+  exceptions.
+
+- Issue #19619: str.encode, bytes.decode and bytearray.decode now use an
+  internal API to throw LookupError for known non-text encodings, rather
+  than attempting the encoding or decoding operation and then throwing a
+  TypeError for an unexpected output type. (The latter mechanism remains
+  in place for third party non-text encodings)
+
+- Issue #19183: Implement PEP 456 'secure and interchangeable hash algorithm'.
+  Python now uses SipHash24 on all major platforms.
+
+- Issue #12892: The utf-16* and utf-32* encoders no longer allow surrogate code
+  points (U+D800-U+DFFF) to be encoded.  The utf-32* decoders no longer decode
+  byte sequences that correspond to surrogate code points.  The surrogatepass
+  error handler now works with the utf-16* and utf-32* codecs.  Based on
+  patches by Victor Stinner and Kang-Hao (Kenny) Lu.
+
+- Issue #17806: Added keyword-argument support for "tabsize" to
+  str/bytes.expandtabs().
+
+- Issue #17828: Output type errors in str.encode(), bytes.decode() and
+  bytearray.decode() now direct users to codecs.encode() or codecs.decode()
+  as appropriate.
+
+- Issue #17828: The interpreter now attempts to chain errors that occur in
+  codec processing with a replacement exception of the same type that
+  includes the codec name in the error message. It ensures it only does this
+  when the creation of the replacement exception won't lose any information.
+
+- Issue #19466: Clear the frames of daemon threads earlier during the
+  Python shutdown to call object destructors. So "unclosed file" resource
+  warnings are now correctly emitted for daemon threads.
+
+- Issue #19514: Deduplicate some _Py_IDENTIFIER declarations.
+  Patch by Andrei Dorian Duma.
+
+- Issue #17936: Fix O(n**2) behaviour when adding or removing many subclasses
+  of a given type.
+
+- Issue #19428: zipimport now handles errors when reading truncated or invalid
+  ZIP archive.
+
+- Issue #18408: Add a new PyFrame_FastToLocalsWithError() function to handle
+  exceptions when merging fast locals into f_locals of a frame.
+  PyEval_GetLocals() now raises an exception and return NULL on failure.
+
+- Issue #19369: Optimized the usage of __length_hint__().
+
+- Issue #28026: Raise ImportError when exec_module() exists but
+  create_module() is missing.
+
+- Issue #18603: Ensure that PyOS_mystricmp and PyOS_mystrnicmp are in the
+  Python executable and not removed by the linker's optimizer.
+
+- Issue #19306: Add extra hints to the faulthandler module's stack
+  dumps that these are "upside down".
+
+Library
+-------
+
+- Issue #3158: doctest can now find doctests in functions and methods
+  written in C.
+
+- Issue #13477: Added command line interface to the tarfile module.

+What's New in Python 3.4.0 Alpha 4?
+===================================
+
+Release date: 2013-10-20

+
+- Issue #19279: UTF-7 decoder no longer produces illegal strings.
+
+- Issue #16612: Add "Argument Clinic", a compile-time preprocessor for

+  directory.
+
+- Issue #18416: importlib.machinery.PathFinder now treats '' as the cwd and
+  importlib.machinery.FileFinder no longer special-cases '' to '.'. This leads
+  to modules imported from cwd to now possess an absolute file path for

+  does affect -m/runpy). It also allows FileFinder to be more consistent by not
+  having an edge case.

+- Issue #19130: Correct PCbuild/readme.txt, Python 3.3 and 3.4 require VS 2010.
+
+- Issue #15663: Update OS X 10.6+ installer to use Tcl/Tk 8.5.15.
+
+- Issue #14499: Fix several problems with OS X universal build support:
+    1. ppc arch detection for extension module builds broke with Xcode 5
+    2. ppc arch detection in configure did not work on OS X 10.4
+    3. -sysroot and -arch flags were unnecessarily duplicated
+    4. there was no obvious way to configure an intel-32 only build.
+
+- Issue #19019: Change the OS X installer build script to use CFLAGS instead
+  of OPT for special build options.  By setting OPT, some compiler-specific
+  options like -fwrapv were overridden and thus not used, which could result
+  in broken interpreters when building with clang.

+  descriptor, so as to avoid using many file descriptors when run in
+  parallel from multiple threads.
+
+- Issue #18418: After fork(), reinit all threads states, not only active ones.
+  Patch by A. Jesse Jiryu Davis.

+- Issue #18178: Fix ctypes on BSD. dlmalloc.c was compiled twice which broke
+  malloc weak symbols.
+
+- Issue #18709: Fix CVE-2013-4238. The SSL module now handles NULL bytes
+  inside subjectAltName correctly. Formerly the module has used OpenSSL's

+  retrying. Report and fix by Vlad Shcherbina.
+
+- Issue #18920: argparse's default destination for the version action (-v,
+  --version) has also been changed to stdout, to match the Python executable.
+
+Tests
+-----
+
+- Issue #18623: Factor out the _SuppressCoreFiles context manager into
+  test.support.  Patch by Valerie Lambert.

+- Issue #12037: Fix test_email for desktop Windows.
+
+- Issue #15507: test_subprocess's test_send_signal could fail if the test
+  runner were run in an environment where the process inherited an ignore
+  setting for SIGINT.  Restore the SIGINT handler to the desired
+  KeyboardInterrupt raising one during that test.
+
+- Issue #16799: Switched from getopt to argparse style in regrtest's argument
+  parsing.  Added more tests for regrtest's argument parsing.
+
+- Issue #18792: Use "127.0.0.1" or "::1" instead of "localhost" as much as
+  possible, since "localhost" goes through a DNS lookup under recent Windows
+  versions.
+
+IDLE
+----
+

+
+Documentation
+-------------

+  error messages and comments.
+
+Build
+-----
+
+- Issue #1584: Provide configure options to override default search paths for
+  Tcl and Tk when building _tkinter.
+
+- Issue #15663: Tcl/Tk 8.5.14 is now included with the OS X 10.6+ 64-/32-bit
+  installer.  It is no longer necessary to install a third-party version of

+  shipped in OS X 10.6 and later releases.
+
+Tools/Demos
+-----------
+
+- Issue #18922: Now The Lib/smtpd.py and Tools/i18n/msgfmt.py scripts write

-
-What's New in Python 3.4.0 release candidate 1?
-===============================================
-
-Release date: 2014-02-10
-
-Core and Builtins
------------------
-
-- Issue #19255: The builtins module is restored to initial value before
-  cleaning other modules.  The sys and builtins modules are cleaned last.
-
-- Issue #20588: Make Python-ast.c C89 compliant.
-
-- Issue #20437: Fixed 22 potential bugs when deleting object references.
-
-- Issue #20500: Displaying an exception at interpreter shutdown no longer
-  risks triggering an assertion failure in PyObject_Str.
-
-- Issue #20538: UTF-7 incremental decoder produced inconsistent string when
-  input was truncated in BASE64 section.
-
-- Issue #20404: io.TextIOWrapper (and hence the open() builtin) now uses the
-  internal codec marking system added for issue #19619 to throw LookupError
-  for known non-text encodings at stream construction time. The existing
-  output type checks remain in place to deal with unmarked third party
-  codecs.
-
-- Issue #17162: Add PyType_GetSlot.
-
-- Issue #20162: Fix an alignment issue in the siphash24() hash function which
-  caused a crash on PowerPC 64-bit (ppc64).
-
-Library
--------
-
-- Issue #20530: The signatures for slot builtins have been updated
-  to reflect the fact that they only accept positional-only arguments.
-
-- Issue #20517: Functions in the os module that accept two filenames
-  now register both filenames in the exception on failure.
-
-- Issue #20563: The ipaddress module API is now considered stable.
-
-- Issue #14983: email.generator now always adds a line end after each MIME
-  boundary marker, instead of doing so only when there is an epilogue.  This
-  fixes an RFC compliance bug and solves an issue with signed MIME parts.
-
-- Issue #20540: Fix a performance regression (vs. Python 3.2) when layering
-  a multiprocessing Connection over a TCP socket.  For small payloads, Nagle's
-  algorithm would introduce idle delays before the entire transmission of a
-  message.
-
-- Issue #16983: the new email header parsing code will now decode encoded words
-  that are (incorrectly) surrounded by quotes, and register a defect.
-
-- Issue #19772: email.generator no longer mutates the message object when
-  doing a down-transform from 8bit to 7bit CTEs.
-
-- Issue #20536: the statistics module now correctly handle Decimal instances
-  with positive exponents
-
-- Issue #18805: the netmask/hostmask parsing in ipaddress now more reliably
-  filters out illegal values and correctly allows any valid prefix length.
-
-- Issue #20481: For at least Python 3.4, the statistics module will require
-  that all inputs for a single operation be of a single consistent type, or
-  else a mixed of ints and a single other consistent type. This avoids
-  some interoperability issues that arose with the previous approach of
-  coercing to a suitable common type.
-
-- Issue #20478: the statistics module now treats collections.Counter inputs
-  like any other iterable.
-
-- Issue #17369: get_filename was raising an exception if the filename
-  parameter's RFC2231 encoding was broken in certain ways.  This was
-  a regression relative to python2.
-
-- Issue #20013: Some imap servers disconnect if the current mailbox is
-  deleted, and imaplib did not handle that case gracefully.  Now it
-  handles the 'bye' correctly.
-
-- Issue #20531: Revert 3.4 version of fix for #19063, and apply the 3.3
-  version.  That is, do *not* raise an error if unicode is passed to
-  email.message.Message.set_payload.
-
-- Issue #20476: If a non-compat32 policy is used with any of the email parsers,
-  EmailMessage is now used as the factory class.  The factory class should
-  really come from the policy; that will get fixed in 3.5.
-
-- Issue #19920: TarFile.list() no longer fails when outputs a listing
-  containing non-encodable characters.  Based on patch by Vajrasky Kok.
-
-- Issue #20515: Fix NULL pointer dereference introduced by issue #20368.
-
-- Issue #19186: Restore namespacing of expat symbols inside the pyexpat module.
-
-- Issue #20053: ensurepip (and hence venv) are no longer affected by the
-  settings in the default pip configuration file.
-
-- Issue #20426: When passing the re.DEBUG flag, re.compile() displays the
-  debug output every time it is called, regardless of the compilation cache.
-
-- Issue #20368: The null character now correctly passed from Tcl to Python.
-  Improved error handling in variables-related commands.
-
-- Issue #20435: Fix _pyio.StringIO.getvalue() to take into account newline
-  translation settings.
-
-- tracemalloc: Fix slicing traces and fix slicing a traceback.
-
-- Issue #20354: Fix an alignment issue in the tracemalloc module on 64-bit
-  platforms. Bug seen on 64-bit Linux when using "make profile-opt".
-
-- Issue #17159: inspect.signature now accepts duck types of functions,
-  which adds support for Cython functions. Initial patch by Stefan Behnel.
-
-- Issue #18801: Fix inspect.classify_class_attrs to correctly classify
-  object.__new__ and object.__init__.
-
-- Fixed cmath.isinf's name in its argument parsing code.
-
-- Issue #20311, #20452: poll and epoll now round the timeout away from zero,
-  instead of rounding towards zero, in select and selectors modules:
-  select.epoll.poll(), selectors.PollSelector.poll() and
-  selectors.EpollSelector.poll(). For example, a timeout of one microsecond
-  (1e-6) is now rounded to one millisecondi (1e-3), instead of being rounded to
-  zero.  However, the granularity property and asyncio's resolution feature
-  were removed again.
-
-- asyncio: Some refactoring; various fixes; add write flow control to
-  unix pipes; Future.set_exception() instantiates the exception
-  argument if it is a class; improved proactor pipe transport; support
-  wait_for(f, None); don't log broken/disconnected pipes; use
-  ValueError instead of assert for forbidden subprocess_{shell,exec}
-  arguments; added a convenience API for subprocess management; added
-  StreamReader.at_eof(); properly handle duplicate coroutines/futures
-  in gather(), wait(), as_completed(); use a bytearray for buffering
-  in StreamReader; and more.

-- Issue #20288: fix handling of invalid numeric charrefs in HTMLParser.
-
-- Issue #20424: Python implementation of io.StringIO now supports lone surrogates.
-
-- Issue #20308: inspect.signature now works on classes without user-defined
-  __init__ or __new__ methods.
-
-- Issue #20372: inspect.getfile (and a bunch of other inspect functions that
-  use it) doesn't crash with unexpected AttributeError on classes defined in C
-  without __module__.
-
-- Issue #20356: inspect.signature formatting uses '/' to separate
-  positional-only parameters from others.
-
-- Issue #20223: inspect.signature now supports methods defined with
-  functools.partialmethods.
-
-- Issue #19456: ntpath.join() now joins relative paths correctly when a drive

-
-Tools/Demos
------------
-
-- Issue #20530: Argument Clinic's signature format has been revised again.
-  The new syntax is highly human readable while still preventing false
-  positives.  The syntax also extends Python syntax to denote "self" and
-  positional-only parameters, allowing inspect.Signature objects to be
-  totally accurate for all supported builtins in Python 3.4.
-
-- Issue #20456: Argument Clinic now observes the C preprocessor conditional
-  compilation statements of the C files it parses.  When a Clinic block is
-  inside a conditional code, it adjusts its output to match, including
-  automatically generating an empty methoddef macro.
-
-- Issue #20456: Cloned functions in Argument Clinic now use the correct
-  name, not the name of the function they were cloned from, for text
-  strings inside generated code.
-
-- Issue #20456: Fixed Argument Clinic's test suite and "--converters" feature.
-
-- Issue #20456: Argument Clinic now allows specifying different names
-  for a parameter in Python and C, using "as" on the parameter line.
-
-- Issue #20326: Argument Clinic now uses a simple, unique signature to
-  annotate text signatures in docstrings, resulting in fewer false
-  positives.  "self" parameters are also explicitly marked, allowing
-  inspect.Signature() to authoritatively detect (and skip) said parameters.
-
-- Issue #20326: Argument Clinic now generates separate checksums for the
-  input and output sections of the block, allowing external tools to verify
-  that the input has not changed (and thus the output is not out-of-date).
-
-Build
------
-
-- Issue #20465: Update SQLite shipped with OS X installer to 3.8.3.
-
-C-API
------
-
-- Issue #20517: Added new functions allowing OSError exceptions to reference
-  two filenames instead of one: PyErr_SetFromErrnoWithFilenameObjects() and
-  PyErr_SetExcFromWindowsErrWithFilenameObjects().
-
-Documentation
--------------
-
-- Issue #20488: Change wording to say importlib is *the* implementation of
-  import instead of just *an* implementation.
-
-- Issue #6386: Clarify in the tutorial that specifying a symlink to execute
-  means the directory containing the executed script and not the symlink is
-  added to sys.path.
-
-
-What's New in Python 3.4.0 Beta 3?
-==================================
-
-Release date: 2014-01-26
-
-Core and Builtins
------------------
-
-- Issue #20189: Four additional builtin types (PyTypeObject,
-  PyMethodDescr_Type, _PyMethodWrapper_Type, and PyWrapperDescr_Type)
-  have been modified to provide introspection information for builtins.
-
-- Issue #17825: Cursor "^" is correctly positioned for SyntaxError and
-  IndentationError.
-
-- Issue #2382: SyntaxError cursor "^" is now written at correct position in most
-  cases when multibyte characters are in line (before "^").  This still not
-  works correctly with wide East Asian characters.
-
-- Issue #18960: The first line of Python script could be executed twice when
-  the source encoding was specified on the second line.  Now the source encoding
-  declaration on the second line isn't effective if the first line contains
-  anything except a comment.  'python -x' works now again with files with the
-  source encoding declarations, and can be used to make Python batch files
-  on Windows.
-
-Library
--------
-
-- asyncio: Various improvements and small changes not all covered by
-  issues listed below.  E.g. wait_for() now cancels the inner task if
-  the timeout occcurs; tweaked the set of exported symbols; renamed
-  Empty/Full to QueueEmpty/QueueFull; "with (yield from lock)" now
-  uses a separate context manager; readexactly() raises if not enough
-  data was read; PTY support tweaks.
-
-- Issue #20311: asyncio: Add a granularity attribute to BaseEventLoop: maximum
-  between the resolution of the BaseEventLoop.time() method and the resolution
-  of the selector. The granuarility is used in the scheduler to round time and
-  deadline.
-
-- Issue #20311: selectors: Add a resolution attribute to BaseSelector.
-
-- Issue #20189: unittest.mock now no longer assumes that any object for
-  which it could get an inspect.Signature is a callable written in Python.
-  Fix courtesy of Michael Foord.
-
-- Issue #20317: ExitStack.__exit__ could create a self-referential loop if an
-  exception raised by a cleanup operation already had its context set
-  correctly (for example, by the @contextmanager decorator). The infinite
-  loop this caused is now avoided by checking if the expected context is
-  already set before trying to fix it.
-
-- Issue #20374: Fix build with GNU readline >= 6.3.
-
-- Issue #20262: Warnings are raised now when duplicate names are added in the
-  ZIP file or too long ZIP file comment is truncated.
-
-- Issue #20165: The unittest module no longer considers tests marked with
-  @expectedFailure successful if they pass.
-

-
-- Issue #20238: TarFile opened with external fileobj and "w:gz" mode didn't
-  write complete output on close.
-
-- Issue #20245: The open functions in the tarfile module now correctly handle
-  empty mode.
-
-- Issue #20242: Fixed basicConfig() format strings for the alternative
-  formatting styles. Thanks to kespindler for the bug report and patch.
-
-- Issue #20246: Fix buffer overflow in socket.recvfrom_into.
-
-- Issues #20206 and #5803: Fix edge case in email.quoprimime.encode where it
-  truncated lines ending in a character needing encoding but no newline by
-  using a more efficient algorithm that doesn't have the bug.
-
-- Issue #19082: Working xmlrpc.server and xmlrpc.client examples. Both in
-  modules and in documentation. Initial patch contributed by Vajrasky Kok.
-
-- Issue #20138: The wsgiref.application_uri() and wsgiref.request_uri()
-  functions now conform to PEP 3333 when handle non-ASCII URLs.
-
-- Issue #19097: Raise the correct Exception when cgi.FieldStorage is given an

-What's New in Python 3.4.0 Beta 2?
-==================================
-
-Release date: 2014-01-05
-
-Core and Builtins
------------------
-
-- Issue #17432: Drop UCS2 from names of Unicode functions in python3.def.

-- Issue #19995: %c, %o, %x, and %X now issue a DeprecationWarning on non-integer
-  input; reworded docs to clarify that an integer type should define both __int__
-  and __index__.
-
-- Issue #19787: PyThread_set_key_value() now always set the value. In Python
-  3.3, the function did nothing if the key already exists (if the current value
-  is a non-NULL pointer).
-
-- Issue #14432: Remove the thread state field from the frame structure. Fix a
-  crash when a generator is created in a C thread that is destroyed while the
-  generator is still used. The issue was that a generator contains a frame, and
-  the frame kept a reference to the Python state of the destroyed C thread. The
-  crash occurs when a trace function is setup.
-
-- Issue #19576: PyGILState_Ensure() now initializes threads. At startup, Python
-  has no concrete GIL. If PyGILState_Ensure() is called from a new thread for
-  the first time and PyEval_InitThreads() was not called yet, a GIL needs to be
-  created.
-
-- Issue #17576: Deprecation warning emitted now when __int__() or __index__()
-  return not int instance.
-
-- Issue #19932: Fix typo in import.h, missing whitespaces in function prototypes.

-  odd behaviour based on user configuration settings
-
-- Fix TypeError on "setup.py upload --show-response".

-  otherwise rely on parent modules being correctly imported prior to
-  execution.
-
-- Issue #19921: When Path.mkdir() is called with parents=True, any missing
-  parent is created with the default permissions, ignoring the mode argument
-  (mimicking the POSIX "mkdir -p" command).
-
-- Issue #19887: Improve the Path.resolve() algorithm to support certain
-  symlink chains.
-
-- Issue #19912: Fixed numerous bugs in ntpath.splitunc().

-
-- Issue #19063: if a Charset's body_encoding was set to None, the email

-
-- Issue #19944: Fix importlib.find_spec() so it imports parents as needed
-  and move the function to importlib.util.
-
-- Issue #19880: Fix a reference leak in unittest.TestCase. Explicitly break
-  reference cycles between frames and the _Outcome instance.
-
-- Issue #17429: platform.linux_distribution() now decodes files from the UTF-8
-  encoding with the surrogateescape error handler, instead of decoding from the
-  locale encoding in strict mode. It fixes the function on Fedora 19 which is
-  probably the first major distribution release with a non-ASCII name. Patch
-  written by Toshio Kuratomi.
-
-- Issue #19343: Expose FreeBSD-specific APIs in resource module.  Original
-  patch by Koobs.
-
-- Issue #19929: Call os.read with 32768 within subprocess.Popen.communicate

-
-- Issue #19927: Add __eq__ to path-based loaders in importlib.
-
-- Issue #19827: On UNIX, setblocking() and settimeout() methods of

-What's New in Python 3.4.0 Beta 1?
-==================================
-
-Release date: 2013-11-24
-
-Core and Builtins
------------------
-
-- Use the repr of a module name in more places in import, especially
-  exceptions.
-
-- Issue #19619: str.encode, bytes.decode and bytearray.decode now use an
-  internal API to throw LookupError for known non-text encodings, rather
-  than attempting the encoding or decoding operation and then throwing a
-  TypeError for an unexpected output type. (The latter mechanism remains
-  in place for third party non-text encodings)
-
-- Issue #19183: Implement PEP 456 'secure and interchangeable hash algorithm'.
-  Python now uses SipHash24 on all major platforms.
-
-- Issue #12892: The utf-16* and utf-32* encoders no longer allow surrogate code
-  points (U+D800-U+DFFF) to be encoded.  The utf-32* decoders no longer decode
-  byte sequences that correspond to surrogate code points.  The surrogatepass
-  error handler now works with the utf-16* and utf-32* codecs.  Based on
-  patches by Victor Stinner and Kang-Hao (Kenny) Lu.
-
-- Issue #17806: Added keyword-argument support for "tabsize" to
-  str/bytes.expandtabs().
-
-- Issue #17828: Output type errors in str.encode(), bytes.decode() and
-  bytearray.decode() now direct users to codecs.encode() or codecs.decode()
-  as appropriate.
-
-- Issue #17828: The interpreter now attempts to chain errors that occur in
-  codec processing with a replacement exception of the same type that
-  includes the codec name in the error message. It ensures it only does this
-  when the creation of the replacement exception won't lose any information.
-
-- Issue #19466: Clear the frames of daemon threads earlier during the
-  Python shutdown to call object destructors. So "unclosed file" resource
-  warnings are now correctly emitted for daemon threads.
-
-- Issue #19514: Deduplicate some _Py_IDENTIFIER declarations.
-  Patch by Andrei Dorian Duma.
-
-- Issue #17936: Fix O(n**2) behaviour when adding or removing many subclasses
-  of a given type.
-
-- Issue #19428: zipimport now handles errors when reading truncated or invalid
-  ZIP archive.
-
-- Issue #18408: Add a new PyFrame_FastToLocalsWithError() function to handle
-  exceptions when merging fast locals into f_locals of a frame.
-  PyEval_GetLocals() now raises an exception and return NULL on failure.

-  Python executable and not removed by the linker's optimizer.
-
-- Issue #19306: Add extra hints to the faulthandler module's stack
-  dumps that these are "upside down".

-  computes the stack effect of bytecode instructions.
-
-- Issue #19735: Implement private function ssl._create_stdlib_context() to
-  create SSLContext objects in Python's stdlib module. It provides a single
-  configuration point and makes use of SSLContext.load_default_certs().
-
-- Issue #16203: Add re.fullmatch() function and regex.fullmatch() method,
-  which anchor the pattern at both ends of the string to match.

-  under Windows.
-
-- Issue #17201: ZIP64 extensions now are enabled by default.  Patch by
-  William Mallard.
-
-- Issue #19292: Add SSLContext.load_default_certs() to load default root CA
-  certificates from default stores or system stores. By default the method
-  loads CA certs for authentication of server certs.
-

-===================================
-
-Release date: 2013-10-20

-  does affect -m/runpy). It also allows FileFinder to be more consistent by not
-  having an edge case.

-
-- Issue #19266: Rename the new-in-3.4 ``contextlib.ignore`` context manager

-    4. there was no obvious way to configure an intel-32 only build.
-
-- Issue #19019: Change the OS X installer build script to use CFLAGS instead
-  of OPT for special build options.  By setting OPT, some compiler-specific

-
-Core and Builtins
------------------
-
-- Issue #18942: sys._debugmallocstats() output was damaged on Windows.
-
-- Issue #18571: Implementation of the PEP 446: file descriptors and file
-  handles are now created non-inheritable; add functions

-
-- Issue #18771: Add optimization to set object lookups to reduce the cost
-  of hash collisions.  The core idea is to inspect a second key/hash pair
-  for each cache line retrieved.
-
