 -- Issue #10299: List the built-in functions in a table in functions.rst.
 -
 -
 -What's New in Python 3.2 Alpha 4?
 -=================================
 -
 -*Release date: 13-Nov-2010*
 -
 -Core and Builtins
 ------------------
 -
 -- Issue #10372: Import the warnings module only after the IO library is
 -  initialized, so as to avoid bootstrap issues with the '-W' option.
 -
 -- Issue #10293: Remove obsolete field in the PyMemoryView structure, unused
 -  undocumented value PyBUF_SHADOW, and strangely-looking code in
 -  PyMemoryView_GetContiguous.
 -
 -- Issue #6081: Add str.format_map(), similar to ``str.format(**mapping)``.
 -
 -- If FileIO.__init__ fails, close the file descriptor.
 -
 -- Issue #10221: dict.pop(k) now has a key error message that includes the
 -  missing key (same message d[k] returns for missing keys).
 -
 -- Issue #5437: A preallocated MemoryError instance should not keep traceback
 -  data (including local variables caught in the stack trace) alive infinitely.
 -
 -- Issue #10186: Fix the SyntaxError caret when the offset is equal to the length
 -  of the offending line.
 -
 -- Issue #10089: Add support for arbitrary -X options on the command line.  They
 -  can be retrieved through a new attribute ``sys._xoptions``.
 -
 -- Issue #4388: On Mac OS X, decode command line arguments from UTF-8, instead of
 -  the locale encoding.  If the LANG (and LC_ALL and LC_CTYPE) environment
 -  variable is not set, the locale encoding is ISO-8859-1, whereas most programs
 -  (including Python) expect UTF-8.  Python already uses UTF-8 for the filesystem
 -  encoding and to encode command line arguments on this OS.
 -
 -- Issue #9713, #10114: Parser functions (e.g. PyParser_ASTFromFile) expect
 -  filenames encoded to the filesystem encoding with the surrogateescape error
 -  handler (to support undecodable bytes), instead of UTF-8 in strict mode.
 -
 -- Issue #9997: Don't let the name "top" have special significance in scope
 -  resolution.
 -
 -- Issue #9862: Compensate for broken PIPE_BUF in AIX by hard coding its value as
 -  the default 512 when compiling on AIX.
 -
 -- Use locale encoding instead of UTF-8 to encode and decode filenames if
 -  Py_FileSystemDefaultEncoding is not set.
 -
 -- Issue #10095: fp_setreadl() doesn't reopen the file, instead reuse the file
 -  descriptor.
 -
 -- Issue #9418: Moved private string methods ``_formatter_parser`` and
 -  ``_formatter_field_name_split`` into a new ``_string`` module.
 -
 -- Issue #9992: Remove PYTHONFSENCODING environment variable.
 -
 -Library
 --------
 -
 -- Issue #10465: fix broken delegating of attributes by gzip._PaddedFile.
 -
 -- Issue #10356: Decimal.__hash__(-1) should return -2.
 -
 -- Issue #1553375: logging: Added stack_info kwarg to display stack information.
 -
 -- Issue #5111: IPv6 Host in the Header is wrapped inside [ ]. Patch by Chandru.
 -
 -- Fix Fraction.__hash__ so that Fraction.__hash__(-1) is -2.  (See also issue
 -  #10356.)
 -
 -- Issue #4471: Add the IMAP.starttls() method to enable encryption on standard
 -  IMAP4 connections.  Original patch by Lorenzo M. Catucci.
 -
 -- Issue #1466065: Add 'validate' option to base64.b64decode to raise an error if
 -  there are non-base64 alphabet characters in the input.
 -
 -- Issue #10386: Add __all__ to token module; this simplifies importing in
 -  tokenize module and prevents leaking of private names through ``import *``.
 -
 -- Issue #4471: Properly shutdown socket in IMAP.shutdown().  Patch by Lorenzo
 -  M. Catucci.
 -
 -- Fix IMAP.login() to work properly.
 -
 -- Issue #9244: multiprocessing pool worker processes could terminate
 -  unexpectedly if the return value of a task could not be pickled.  Only the
 -  ``repr`` of such errors are now sent back, wrapped in an
 -  ``MaybeEncodingError`` exception.
 -
 -- Issue #9244: The ``apply_async()`` and ``map_async()`` methods of
 -  ``multiprocessing.Pool`` now accepts a ``error_callback`` argument.  This can
 -  be a callback with the signature ``callback(exc)``, which will be called if
 -  the target raises an exception.
 -
 -- Issue #10022: The dictionary returned by the ``getpeercert()`` method of SSL
 -  sockets now has additional items such as ``issuer`` and ``notBefore``.
 -
 -- ``usenetrc`` is now false by default for NNTP objects.
 -
 -- Issue #1926: Add support for NNTP over SSL on port 563, as well as STARTTLS.
 -  Patch by Andrew Vant.
 -
 -- Issue #10335: Add tokenize.open(), detect the file encoding using
 -  tokenize.detect_encoding() and open it in read only mode.
 -
 -- Issue #10321: Add support for binary data to smtplib.SMTP.sendmail, and a new
 -  method send_message to send an email.message.Message object.
 -
 -- Issue #6011: sysconfig and distutils.sysconfig use the surrogateescape error
 -  handler to parse the Makefile file.  Avoid a UnicodeDecodeError if the source
 -  code directory name contains a non-ASCII character and the locale encoding is
 -  ASCII.
 -
 -- Issue #10329: The trace module writes reports using the input Python script
 -  encoding, instead of the locale encoding.  Patch written by Alexander
 -  Belopolsky.
 -
 -- Issue #10126: Fix distutils' test_build when Python was built with
 -  --enable-shared.
 -
 -- Issue #9281: Prevent race condition with mkdir in distutils.  Patch by
 -  Arfrever.
 -

 -  unpickling them produced nonsensical results.
 -
 -- Issue #10311: The signal module now restores errno before returning from its
 -  low-level signal handler.  Patch by Hallvard B Furuseth.
 -
 -- Issue #10282: Add a ``nntp_implementation`` attribute to NNTP objects.
 -
 -- Issue #10283: Add a ``group_pattern`` argument to NNTP.list().
 -
 -- Issue #10155: Add IISCGIHandler to wsgiref.handlers to support IIS CGI
 -  environment better, and to correct unicode environment values for WSGI 1.0.1.
 -
 -- Issue #10281: nntplib now returns None for absent fields in the OVER/XOVER
 -  response, instead of raising an exception.
 -
 -- wsgiref now implements and validates PEP 3333, rather than an experimental
 -  extension of PEP 333.  (Note: earlier versions of Python 3.x may have
 -  incorrectly validated some non-compliant applications as WSGI compliant; if
 -  your app validates with Python <3.2b1+, but not on this version, it is likely
 -  the case that your app was not compliant.)
 -
 -- Issue #10280: NNTP.nntp_version should reflect the highest version advertised
 -  by the server.
 -
 -- Issue #10184: Touch directories only once when extracting a tarfile.
 -
 -- Issue #10199: New package, ``turtledemo`` now contains selected demo scripts
 -  that were formerly found under Demo/turtle.
 -
 -- Issue #10265: Close file objects explicitly in sunau.  Patch by Brian Brazil.
 -

 -
 -- Support context manager protocol for file-like objects returned by mailbox
 -  ``get_file()`` methods.

 -  encode method now support a 'linesep' argument.
 -
 -- Issue #5639: Add a *server_hostname* argument to ``SSLContext.wrap_socket`` in
 -  order to support the TLS SNI extension.  ``HTTPSConnection`` and ``urlopen()``
 -  also use this argument, so that HTTPS virtual hosts are now supported.

 +  decimal.py: Infinity coefficients are undefined in _decimal (in accordance
 +  with the specification).
  
 -- Issue #9808: Implement os.getlogin for Windows. Patch by Jon Anglin.
 +- Issue #15925: Fix a regression in `email.util` where the `parsedate()` and
 +  `parsedate_tz()` functions did not return None anymore when the argument could
 +  not be parsed.
  
 -- Issue #9901: Destroying the GIL in Py_Finalize() can fail if some other
 -  threads are still running.  Instead, reinitialize the GIL on a second call to
 -  Py_Initialize().
 +Extension Modules
 +-----------------
  
 -- All SyntaxErrors now have a column offset and therefore a caret when the error
 -  is printed.
 +- Issue #15973: Fix a segmentation fault when comparing datetime timezone
 +  objects.
  
 -- Issue #9252: PyImport_Import no longer uses a fromlist hack to return the
 -  module that was imported, but instead gets the module from sys.modules.
 +- Issue #15977: Fix memory leak in Modules/_ssl.c when the function
 +  _set_npn_protocols() is called multiple times, thanks to Daniel Sommermann.
  
 -- Issue #9213: The range type_items now provides index() and count() methods, to
 -  conform to the Sequence ABC.  Patch by Daniel Urban and Daniel Stutzbach.
 +- Issue #15969: `faulthandler` module: rename dump_tracebacks_later() to
 +  dump_traceback_later() and cancel_dump_tracebacks_later() to
 +  cancel_dump_traceback_later().
  
 -- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
 -  with a non-empty format string.  This is an effort to future-proof user
 -  code. If a derived class does not currently implement __format__ but later
 -  adds its own __format__, it would most likely break user code that had
 -  supplied a format string.  This will be changed to a DeprecationWaring in
 -  Python 3.3 and it will be an error in Python 3.4.
 +- _decimal module: use only C 89 style comments.
  
 -- Issue #9828: Destroy the GIL in Py_Finalize(), so that it gets properly
 -  re-created on a subsequent call to Py_Initialize().  The problem (a crash)
 -  wouldn't appear in 3.1 or 2.7 where the GIL's structure is more trivial.
  
 -- Issue #9210: Configure option --with-wctype-functions was removed.  Using the
 -  functions from the libc caused the methods .upper() and lower() to become
 -  locale aware and created subtly wrong results.
 +What's New in Python 3.3.0 Release Candidate 2?
 +===============================================
  
 -- Issue #9738: PyUnicode_FromFormat() and PyErr_Format() raise an error on a
 -  non-ASCII byte in the format string.
 +*Release date: 09-Sep-2012*
  
 -- Issue #4617: Previously it was illegal to delete a name from the local
 -  namespace if it occurs as a free variable in a nested block.  This limitation
 -  of the compiler has been lifted, and a new opcode introduced (DELETE_DEREF).
 +Core and Builtins
 +-----------------
  
 -- Issue #9804: ascii() now always represents unicode surrogate pairs as a single
 -  ``\UXXXXXXXX``, regardless of whether the character is printable or not.
 -  Also, the "backslashreplace" error handler now joins surrogate pairs into a
 -  single character on UCS-2 builds.
 +- Issue #13992: The trashcan mechanism is now thread-safe.  This eliminates
 +  sporadic crashes in multi-thread programs when several long deallocator chains
 +  ran concurrently and involved subclasses of built-in container types.
  
 -- Issue #9757: memoryview objects get a release() method to release the
 -  underlying buffer (previously this was only done when deallocating the
 -  memoryview), and gain support for the context management protocol.
 +- Issue #15784: Modify `OSError`.__str__() to better distinguish between errno
 +  error numbers and Windows error numbers.
  
 -- Issue #9797: pystate.c wrongly assumed that zero couldn't be a valid
 -  thread-local storage key.
 +- Issue #15781: Fix two small race conditions in import's module locking.
