+  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;
+  WriteTransport.set_write_buffer_size() calls _maybe_pause_protocol()
+  to consider pausing receiving if the watermark limits have changed;
+  fix _check_resolved_address() for IPv6 address; and other minor

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

+
+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.

+
+- 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.
+
+- 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 #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
+  invalid fileobj.
+
+- Issue #20152: Ported Python/import.c over to Argument Clinic.
+

+  PathEntryFinder.find_loader(), and Loader.load_module() use PEP 451 APIs to
+  help with backwards-compatibility.
+
+- Issue #20144: inspect.Signature now supports parsing simple symbolic
+  constants as parameter default values in __text_signature__.
+
+- Issue #20072: Fixed multiple errors in tkinter with wantobjects is False.
+
+- Issue #20229: Avoid plistlib deprecation warning in platform.mac_ver().

+
+Tools/Demos
+-----------
+
+- Issue #20390: Argument Clinic's "file" output preset now defaults to
+  "{dirname}/clinic/{basename}.h".
+
+- Issue #20390: Argument Clinic's "class" directive syntax has been extended
+  with two new required arguments: "typedef" and "type_object".
+
+- Issue #20390: Argument Clinic: If __new__ or __init__ functions didn't use
+  kwargs (or args), the PyArg_NoKeywords (or PyArg_NoPositional) calls
+  generated are only run when the type object is an exact match.
+
+- Issue #20390: Argument Clinic now fails if you have required parameters after
+  optional parameters.
+
+- Issue #20390: Argument Clinic converters now have a new template they can
+  inject code into: "modifiers".  Code put there is run in the parsing
+  function after argument parsing but before the call to the impl.
+
+- Issue #20376: Argument Clinic now escapes backslashes in docstrings.
+
+- Issue #20381: Argument Clinic now sanity checks the default argument when
+  c_default is also specified, providing a nice failure message for
+  disallowed values.
+
+- Issue #20189: Argument Clinic now ensures that parser functions for
+  __new__ are always of type newfunc, the type of the tp_new slot.
+  Similarly, parser functions for __init__ are now always of type initproc,
+  the type of tp_init.
+
+- Issue #20189: Argument Clinic now suppresses the docstring for __new__
+  and __init__ functions if no docstring is provided in the input.
+
+- Issue #20189: Argument Clinic now suppresses the "self" parameter in the
+  impl for @staticmethod functions.
+

+- Issue #20299: Argument Clinic custom converters may now change the default
+  value of c_default and py_default with a class member.
+
+- Issue #20287: Argument Clinic's output is now configurable, allowing
+  delaying its output or even redirecting it to a separate file.
+
+- Issue #20226: Argument Clinic now permits simple expressions
+  (e.g. "sys.maxsize - 1") as default values for parameters.
+
+- Issue #19936: Added executable bits or shebang lines to Python scripts which
+  requires them.  Disable executable bits and shebang lines in test and
+  benchmark files in order to prevent using a random system python, and in
+  source files of modules which don't provide command line interface.  Fixed
+  shebang lines in the unittestgui and checkpip scripts.
+
+- Issue #20268: Argument Clinic now supports cloning the parameters and
+  return converter of existing functions.
+
+- Issue #20228: Argument Clinic now has special support for class special
+  methods.
+
+- Issue #20214: Fixed a number of small issues and documentation errors in

+
+- Issue #20196: Fixed a bug where Argument Clinic did not generate correct

+
+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
+-------
+
+- Issue #20154: Deadlock in asyncio.StreamReader.readexactly().
+
+- Issue #16113: Remove sha3 module again.
+
+- Issue #20111: pathlib.Path.with_suffix() now sanity checks the given suffix.
+
+- 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 #5815: Fixed support for locales with modifiers.  Fixed support for
+  locale encodings with hyphens.
+
+- Issue #20026: Fix the sqlite module to handle correctly invalid isolation
+  level (wrong type).
+
+- Issue #18829: csv.Dialect() now checks type for delimiter, escapechar and
+  quotechar fields.  Original patch by Vajrasky Kok.
+
+- Issue #19855: uuid.getnode() on Unix now looks on the PATH for the
+  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.
+
+- Issue #19876: selectors unregister() no longer raises ValueError or OSError
+  if the FD is closed (as long as it was registered).
+

+  is present.  Original patch by Antoine Pitrou.
+
+- Issue #19296: Silence compiler warning in dbm_open
+
+- Issue #6784: Strings from Python 2 can now be unpickled as bytes
+  objects by setting the encoding argument of Unpickler to be 'bytes'.
+  Initial patch by Merlijn van Deen.

+- Issue #19839: Fix regression in bz2 module's handling of non-bzip2 data at
+  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
+  used, or if the non-blocking flag of the socket is unchanged.
+
+- Issue #19785: smtplib now supports SSLContext.check_hostname and server name
+  indication for TLS/SSL connections.
+
+- Issue #19784: poplib now supports SSLContext.check_hostname and server name
+  indication for TLS/SSL connections.

+
+- Issue #17897: Optimized unpickle prefetching.
+
+- Issue #3693: Make the error message more helpful when the array.array()
+  constructor is given a str. Move the array module typecode documentation to
+  the docstring of the constructor.
+
+- Issue #19088: Fixed incorrect caching of the copyreg module in
+  object.__reduce__() and object.__reduce_ex__().
+
+- Issue #19698: Removed exec_module() methods from

+
+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.
+  Original patch by Berker Peksag.
+
+- Issue #19674: inspect.signature() now produces a correct signature
+  for some builtins.
+
+- Issue #19722: Added opcode.stack_effect(), which
+  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.
+  Original patch by Matthew Barnett.
+
+- Issue #13592: Improved the repr for regular expression pattern objects.
+  Based on patch by Hugo Lopes Tavares.
+
+- Issue #19641: Added the audioop.byteswap() function to convert big-endian
+  samples to little-endian and vice versa.
+
+- Issue #15204: Deprecated the 'U' mode in file-like objects.
+
+- Issue #17810: Implement PEP 3154, pickle protocol 4.
+
+- Issue #19668: Added support for the cp1125 encoding.

+  a new SSLContext object with secure default settings.
+
+- Issue #19727: os.utime(..., None) is now potentially more precise
+  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.
+
+- Issue #19673: Add pathlib to the stdlib as a provisional module (PEP 428).
+
+- Issue #16596: pdb in a generator now properly skips over yield and
+  yield from rather than stepping out of the generator into its
+  caller.  (This is essential for stepping through asyncio coroutines.)
+
+- Issue #17916: Added dis.Bytecode.from_traceback() and
+  dis.Bytecode.current_offset to easily display "current instruction"
+  markers in the new disassembly API (Patch by Claudiu Popa).
+
+- Issue #19552: venv now supports bootstrapping pip into virtual environments
+
+- Issue #17134: Finalize interface to Windows' certificate store. Cert and
+  CRL enumeration are now two functions. enum_certificates() also returns
+  purpose flags as set of OIDs.
+
+- Issue #19555: Restore sysconfig.get_config_var('SO'), (and the distutils
+  equivalent) with a DeprecationWarning pointing people at $EXT_SUFFIX.
+
+- Issue #8813: Add SSLContext.verify_flags to change the verification flags
+  of the context in order to enable certification revocation list (CRL)
+  checks or strict X509 rules.
+
+- Issue #18294: Fix the zlib module to make it 64-bit safe.
+
+- Issue #19682: Fix compatibility issue with old version of OpenSSL that
+  was introduced by Issue #18379.

+  big-endian platforms.
+
+- Issue #18379: SSLSocket.getpeercert() returns CA issuer AIA fields, OCSP
+  and CRL distribution points.
+
+- Issue #18138: Implement cadata argument of SSLContext.load_verify_location()
+  to load CA certificates and CRL from memory. It supports PEM and DER
+  encoded strings.
+
+- Issue #18775: Add name and block_size attribute to HMAC object. They now
+  provide the same API elements as non-keyed cryptographic hash functions.
+
+- Issue #17276: MD5 as default digestmod for HMAC is deprecated. The HMAC
+  module supports digestmod names, e.g. hmac.HMAC('sha1').
+
+- Issue #19449: in csv's writerow, handle non-string keys when generating the
+  error message that certain keys are not in the 'fieldnames' list.
+
+- Issue #13633: Added a new convert_charrefs keyword arg to HTMLParser that,
+  when True, automatically converts all character references.
+
+- Issue #2927: Added the unescape() function to the html module.
+
+- Issue #8402: Added the escape() function to the glob module.
+

+
+- Issue #19634: time.strftime("%y") now raises a ValueError on AIX when given a
+  year before 1900.
+
+- Fix test.support.bind_port() to not cause an error when Python was compiled
+  on a system with SO_REUSEPORT defined in the headers but run on a system
+  with an OS kernel that does not support that reasonably new socket option.
+
+- Fix compilation error under gcc of the ctypes module bundled libffi for arm.
+
+- Issue #19448: Add private API to SSL module to lookup ASN.1 objects by OID,
+  NID, short name and long name.
+
+- Issue #19282: dbm.open now supports the context management protocol.
+  (Initial patch by Claudiu Popa)

+  sunau, and wave modules.
+
+- Issue #5202: Added support for unseekable files in the wave module.

+  ~/.pydistutils.cfg in Distutils, accidentally removed in backout of
+  distutils2 changes.
+
+- Issue #19523: Closed FileHandler leak which occurred when delay was set.
+
+- Issue #19544 and Issue #6516: Restore support for --user and --group
+  parameters to sdist command accidentally rolled back as part of the
+  distutils2 rollback.
+
+- Issue #13674: Prevented time.strftime from crashing on Windows when given
+  a year before 1900 and a format of %y.
+

+  Patch by Donald Stufft and Nick Coghlan.
+
+- Issue #19544 and Issue #6286: Restore use of urllib over http allowing use
+  of http_proxy for Distutils upload command, a feature accidentally lost
+  in the rollback of distutils2.

+  to socket module. Patch by Atsuo Ishimoto.
+
+- Issue #19261: Added support for writing 24-bit samples in the sunau module.
+

+  Germany and Austria.  Mapping provided by Michael Bierenfeld.
+
+- Issue #1575020: Fixed support of 24-bit wave files on big-endian platforms.
+
+- Issue #19378: Fixed a number of cases in the dis module where the new
+  "file" parameter was not being honoured correctly
+
+- Issue #19378: Removed the "dis.Bytecode.show_info" method
+
+- Issue #19378: Renamed the "dis.Bytecode.display_code" method to
+  "dis.Bytecode.dis" and converted it to returning a string rather than
+  printing output.
+
+- Issue #19378: the "line_offset" parameter in the new "dis.get_instructions"
+  API has been renamed to "first_line" (and the default value and usage
+  changed accordingly). This should reduce confusion with the more common use
+  of "offset" in the dis docs to refer to bytecode offsets.

+  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
+  __file__ (this does not affect modules specified by path on the CLI but it
+  does affect -m/runpy). It also allows FileFinder to be more consistent by not
+  having an edge case.

+- Issue #19276: Fixed the wave module on 64-bit big-endian platforms.
+
+- Issue #19266: Rename the new-in-3.4 ``contextlib.ignore`` context manager

+  descriptions of that operation elsewhere in the language and standard
+  library documentation (Patch by Zero Piraeus).
+
+- Issue #18891: Completed the new email package (provisional) API additions
+  by adding new classes EmailMessage, MIMEPart, and ContentManager.

+  compressed streams.
+
+- Issue #19209: Remove import of copyreg from the os module to speed up
+  interpreter startup. stat_result and statvfs_result are now hard-coded to
+  reside in the os module.
+
+- Issue #19205: Don't import the 're' module in site and sysconfig module to
+  speed up interpreter start.

+
+- Issue #19030: Fixed `inspect.getmembers` and `inspect.classify_class_attrs`

+    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

+  in broken interpreters when building with clang.

+- 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

+  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
+----
+
+- Issue #18489: Add tests for SearchEngine. Original patch by Phil Webster.

+  shipped in OS X 10.6 and later releases.
+
+Tools/Demos

+- Issue #16416: On Mac OS X, operating system data are now always
+  encoded/decoded to/from UTF-8/surrogateescape, instead of the locale encoding

+  received a nonempty dict from the constructor.
+
+- Issue #16271: Fix strange bugs that resulted from __qualname__ appearing in a
+  class's __dict__ and on type.
